Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a friction pad with high coefficient of friction is applied to secure a device to a surface, then the device retention is improved, but the risk of damaging the device or surface increases
Solution Approach 1:
The friction pad applies local quality by creating a textured surface with raised features only where needed for friction, while keeping the base material smooth and non-damaging. The embossed or textured features are localized to the engagement surface, providing grip without compromising the overall integrity of the pad or the surface it contacts.
Solution Approach 2:
The friction pad provides beforehand cushioning by acting as a protective layer between the device and the surface. The soft, compliant material absorbs and distributes contact forces, preventing direct damage to either the device or the surface while maintaining secure retention through friction.
2Reliability
If a friction pad is designed to provide strong grip on various surfaces, then the anti-slip properties are improved, but the ease of removal without damage deteriorates
Solution Approach 1:
The friction pad utilizes parameter changes by adjusting the coefficient of friction through controlled texturing or embossing of the surface. The raised features increase the local coefficient of friction for secure grip, while the overall material properties remain compliant and non-damaging, allowing easy removal without leaving residue or damage.
3Ease of operation
If the friction pad uses a smooth surface for easy cleaning and maintenance, then the ease of operation is improved, but the friction and grip capability deteriorates
Solution Approach 1:
The friction pad applies local quality by maintaining a smooth base material that is easy to clean and maintain, while incorporating localized textured or embossed features only where friction is needed. This allows the majority of the surface to remain smooth and cleanable, while specific areas provide the necessary grip capability.
