Constraints\u2014and the \u201cfacts\u201d that accompany them\u2014are the lifeblood of development. Designers do not only create new solutions; they also solve product problems. Solving product problems is pragmatic work grounded in facts. But are all those constraints really valid?    <\/h3>\n\n<h2 class=\"wp-block-heading\">The Realities of Solving Product Problems<\/h2>\n\n<p class=\"wp-block-paragraph\">Over the course of my design career, I specialized not only in product design but also in <a href=\"https:\/\/linkdesign.fi\/en\/product-development\/\" target=\"_blank\" rel=\"noreferrer noopener\">solving product problems<\/a>. However effective the processes may be, problems still arise\u2014and they must be resolved quickly to keep the consequences and risks under control. <\/p>\n\n<p class=\"wp-block-paragraph\">Once a product is on the market, every error can create uncontrolled risks and financial liabilities. Prevention is therefore essential. But if the damage has already occurred, the race against time begins.  <\/p>\n\n<h2 class=\"wp-block-heading\">Case: Gearbox Bearing Damage<\/h2>\n\n<p class=\"wp-block-paragraph\">As a young designer, I was once given an assignment by my supervisor: \u201cA customer has asked us to help solve a problem. Jaakko, take a look at this case next.\u201d He remembered that I had once mentioned knowing something about the subject. Pitting corrosion had been detected in the bearings of a machine\u2019s gearbox.<\/p>\n\n<p class=\"wp-block-paragraph\">Pitting was familiar to me from my mechanical engineering studies and materials engineering laboratory work. I had also gained practical experience repairing heavy-equipment gearboxes, where bearing failures were commonplace\u2014usually because of excessive loads or contaminants in the lubricant. <\/p>\n\n<h2 class=\"wp-block-heading\">The Search for Facts Begins<\/h2>\n\n<p class=\"wp-block-paragraph\">After studying the documentation, I quickly realized that the problem was widespread. Damage had occurred in several different types of gearboxes, so I did not believe that a single design or dimensioning error could explain it. <\/p>\n\n<p class=\"wp-block-paragraph\">I approached the problem pragmatically and analytically. I gathered every available fact, categorized the information, and created cause-and-effect tables. I also involved colleagues so that I would not become blind to my own perspective. Although I had tentatively ruled out a design error, I kept it on the list of possibilities.   <\/p>\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img data-opt-id=371439902  fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/mlavatqvr5rz.i.optimole.com\/cb:qpdk.5b1d4\/w:1024\/h:768\/q:mauto\/f:best\/https:\/\/linkdesign.fi\/wp-content\/uploads\/ruosteiset-laakerit.jpg\" alt=\"\" class=\"wp-image-11809\" style=\"width:579px;height:auto\" srcset=\"https:\/\/mlavatqvr5rz.i.optimole.com\/cb:qpdk.5b1d4\/w:1024\/h:768\/q:mauto\/f:best\/https:\/\/linkdesign.fi\/wp-content\/uploads\/ruosteiset-laakerit.jpg 1024w, https:\/\/mlavatqvr5rz.i.optimole.com\/cb:qpdk.5b1d4\/w:300\/h:225\/q:mauto\/f:best\/https:\/\/linkdesign.fi\/wp-content\/uploads\/ruosteiset-laakerit.jpg 300w, https:\/\/mlavatqvr5rz.i.optimole.com\/cb:qpdk.5b1d4\/w:768\/h:576\/q:mauto\/f:best\/https:\/\/linkdesign.fi\/wp-content\/uploads\/ruosteiset-laakerit.jpg 768w, https:\/\/mlavatqvr5rz.i.optimole.com\/cb:qpdk.5b1d4\/w:1087\/h:815\/q:mauto\/f:best\/https:\/\/linkdesign.fi\/wp-content\/uploads\/ruosteiset-laakerit.jpg 1087w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n<div style=\"height:22px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h2 class=\"wp-block-heading\">The Root Cause and the Obvious Solution<\/h2>\n\n<p class=\"wp-block-paragraph\">Together with the development team, we concluded that condensation was causing the pitting. Water accumulated at the bottom of the gearbox, where the bearings rotated\u2014and water is known to cause pitting. The obvious solution was to prevent water from entering the gearbox.  <\/p>\n\n<p class=\"wp-block-paragraph\">I examined the solutions the customer used to prevent water ingress. I found nearly 150 different versions\u2014most of them variations of one another\u2014but not one was completely watertight, literally. <\/p>\n\n<p class=\"wp-block-paragraph\">I developed a new solution that would prevent condensation more effectively and replace as many of the old versions as possible. We tested prototypes, and the results looked promising: condensation was almost entirely eliminated. Production began, and retrofit kits were shipped around the world.  <\/p>\n\n<h2 class=\"wp-block-heading\">No Water\u2014Yet the Damage Continued<\/h2>\n\n<p class=\"wp-block-paragraph\">Our relief was short-lived: the damage continued. Water was no longer the problem, but the bearings were still failing. We were baffled.  <\/p>\n\n<p class=\"wp-block-paragraph\">At the same time, our quality department received a notice from a world-leading German bearing manufacturer: a batch of its bearings had a hardening defect. A sensor failure on the hardening line had caused the wrong temperature, resulting in a quality defect that could manifest as pitting. <\/p>\n\n<p class=\"wp-block-paragraph\">We checked the codes\u2014and yes, those defective bearings were installed in the damaged gearboxes. The root cause was not water but faulty bearings. We had developed the obvious solution\u2014and solved the wrong problem. <\/p>\n\n<p class=\"wp-block-paragraph\">I do not know whether the obvious solution I developed on \u201cfalse grounds\u201d is still in use, but in my opinion, it became an excellent solution. It met the requirements, addressed the assumed problem, and replaced numerous older solutions. In this case, the \u201cfalse prophet\u201d was a product from a world-leading bearing manufacturer\u2014something no one thought to question during the project. Had we questioned it, the project would have been very different.   <\/p>\n\n<h2 class=\"wp-block-heading\">The ABCs of Identifying False Prophets<\/h2>\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\" style=\"grid-template-columns:20% auto\"><figure class=\"wp-block-media-text__media\"><img data-opt-id=1869718745  fetchpriority=\"high\" decoding=\"async\" width=\"500\" height=\"500\" src=\"https:\/\/mlavatqvr5rz.i.optimole.com\/cb:qpdk.5b1d4\/w:auto\/h:auto\/q:mauto\/f:best\/https:\/\/linkdesign.fi\/wp-content\/uploads\/A-pallo.png\" alt=\"\" class=\"wp-image-11803 size-full\" srcset=\"https:\/\/mlavatqvr5rz.i.optimole.com\/cb:qpdk.5b1d4\/w:500\/h:500\/q:mauto\/f:best\/https:\/\/linkdesign.fi\/wp-content\/uploads\/A-pallo.png 500w, https:\/\/mlavatqvr5rz.i.optimole.com\/cb:qpdk.5b1d4\/w:300\/h:300\/q:mauto\/f:best\/https:\/\/linkdesign.fi\/wp-content\/uploads\/A-pallo.png 300w, https:\/\/mlavatqvr5rz.i.optimole.com\/cb:qpdk.5b1d4\/w:150\/h:150\/q:mauto\/f:best\/https:\/\/linkdesign.fi\/wp-content\/uploads\/A-pallo.png 150w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p class=\"wp-block-paragraph\"><strong>Question everything:<\/strong> <br\/>The biggest mistake is blindly believing in \u201cfacts\u201d that have not been properly verified.

The obvious solution is not always the right one. Do not believe everything. Do not assume. Healthy questioning is one of a designer\u2019s most important tools.
