Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid contact structure is used for mounting internal components, then structural strength and stability are improved, but damage probability during drop or collision increases
Solution Approach 1:
The patent changes the mechanical parameter of the mounting member from rigid to elastic by selecting materials with appropriate elasticity modulus. The mounting member is designed to have a deformation amount of 0.015mm to 9.30mm when stressed, transforming it from a rigid component into a shock-absorbing element that protects internal components during drops or collisions while maintaining structural integrity.
Solution Approach 2:
The patent implements beforehand cushioning by designing the mounting member with elastic properties before the drop or collision occurs. The elastic mounting member is pre-configured to deform and absorb impact energy when stress is applied, converting rigid contact into elastic buffer contact, thereby protecting internal components from damage during unexpected drops or collisions.
2Reliability
If elastic mounting member is used to reduce impact stress, then protection against drop damage is improved, but mounting precision and stability may deteriorate
Solution Approach 1:
The patent carefully selects and controls the elasticity parameters of the mounting member to achieve an optimal balance. By specifying a deformation range of 0.015mm to 9.30mm, the mounting member maintains sufficient rigidity for precise mounting while having enough elasticity to absorb impact energy, thus achieving both mounting precision and drop protection.
