Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotary hinge mechanism is used to enable folding, then the foldable mobile phone achieves portability and diversified functions, but friction between rotary components generates heat leading to grease oxidation and severe wear
Solution Approach 1:
A heat dissipation member is introduced as an intermediary component between the rotary components. This heat dissipation member includes a heat dissipation cavity filled with cooling medium (liquid or gel), which acts as a mediator to transfer heat away from the friction points, preventing grease oxidation and reducing wear while maintaining the rotary mechanism's functionality
Solution Approach 2:
The invention changes the thermal parameters of the rotary mechanism by introducing a cooling system. The heat dissipation member with cooling medium alters the temperature parameter, maintaining it within a range that prevents grease oxidation. This parameter change (temperature control) directly addresses the wear problem while preserving the folding function
2Volume of moving object
If rotary components are used for folding, then the device achieves compact folding capability, but heat generation from friction causes grease oxidation and severe wear
Solution Approach 1:
The heat dissipation member serves as an intermediary that absorbs and transfers heat away from the rotary components. The cooling medium within the heat dissipation cavity acts as a thermal mediator, preventing harmful heat accumulation that would otherwise cause grease oxidation and material degradation
Solution Approach 2:
The invention converts the harmful heat generated by friction into a manageable thermal flow. By introducing the heat dissipation member with cooling medium, the previously harmful heat is transformed into a controlled thermal transfer process, where the heat is systematically removed through the cooling system, turning a detrimental effect into a controlled phenomenon
