Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed protective cases are used, then the structure is simple and easy to manufacture, but the device cannot achieve 360-degree free rotation and angle adjustment
Solution Approach 1:
The protective case is divided into multiple functional components: a main body, a rotatable bottom support with limiting columns, a surface support with elastic positioning parts, and a detachable supporting plate. This segmentation allows each component to perform specific functions (rotation, positioning, support) while maintaining overall simplicity and manufacturability.
Solution Approach 2:
The case transitions from a fixed structure to a dynamic one by incorporating the rotatable bottom support that enables 360-degree rotation and the supporting plate that can be detached and positioned at various angles. The elastic positioning parts provide dynamic adjustment capability while maintaining stability during use.
2Manufacturing precision
If elastic positioning parts made of plastic are used, then production and assembly errors are solved and noise is reduced, but the positioning mechanism becomes more complex
Solution Approach 1:
The elastic positioning parts are made of plastic material that can deform elastically to accommodate minor production and assembly errors. The elasticity parameter of the plastic allows the positioning parts to self-adjust and maintain accurate positioning without requiring extremely precise manufacturing tolerances.
Solution Approach 2:
The elastic positioning parts act as intermediaries between the surface support and the bottom support, absorbing dimensional variations and providing smooth, quiet operation during rotation. The plastic material serves as a mediator that reduces noise while maintaining positioning function.
3Adaptability or versatility
If the supporting plate is hinged to allow angle adjustment, then the adaptability is improved, but the structural complexity increases
Solution Approach 1:
The supporting plate is hinged to the surface support, transforming it from a fixed component to a dynamic one that can be adjusted to various angles. This simple hinge mechanism provides the necessary adaptability for different viewing and usage positions without requiring complex actuation systems.
Solution Approach 2:
The hinged supporting plate serves multiple functions: it provides angle adjustment for viewing comfort, acts as a stand when detached, and can be positioned at various orientations. This single component fulfills multiple user needs, enhancing versatility without proportionally increasing complexity.
