Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If an elastic sheet is used in the damping mechanism, then a sufficient elastic force can be provided, but a large housing space is required and noises are easily generated by friction
Solution Approach 1:
The patent changes the material parameter from traditional metal elastic sheets to polyoxymethylene (POM) self-lubricating material. This material parameter change provides sufficient elastic force while reducing friction noise and allowing for a more compact housing space due to the material's inherent lubricating properties that reduce the need for large clearance spaces.
Solution Approach 2:
The patent employs composite material structure by combining POM self-lubricating material with the damping mechanism components. This composite approach integrates the elastic function and self-lubrication properties into a single material system, eliminating the need for separate lubrication systems and reducing overall housing space requirements.
2Force
If an elastic sheet is used in the damping mechanism, then a sufficient elastic force can be provided, but noises are easily generated by the friction between the elastic sheet and the housing
Solution Approach 1:
The patent changes the material parameter from traditional metal elastic sheets to polyoxymethylene (POM) self-lubricating material. This material parameter change provides sufficient elastic force while reducing friction noise due to the material's inherent low-friction properties, directly addressing the noise issue without compromising elastic force.
Solution Approach 2:
The patent converts the harmful friction effect into a beneficial self-lubricating effect by using POM material. The friction that previously generated noise is transformed into controlled friction with self-lubrication properties, where the material's molecular structure provides inherent lubrication that reduces noise while maintaining necessary friction for damping function.
3Force
If a soft component such as silica gel is disposed on the sliding member, then damping can be generated, but the amount of deformation is difficult to control resulting in unstable damping feel
Solution Approach 1:
The patent changes the material parameter from soft components like silica gel to polyoxymethylene (POM) self-lubricating material with controlled mechanical properties. This material provides consistent elastic modulus and controlled deformation characteristics, ensuring stable damping feel while maintaining sufficient damping force through its engineered material properties.
