Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If power supply and circuitry are arranged along intersecting reference planes in the base member, then space utilization and integration efficiency are improved, but manufacturing complexity increases
Solution Approach 1:
The patent transitions from conventional linear or planar arrangements to a three-dimensional configuration where the power supply and circuitry are arranged along two different reference planes that intersect within the base member. This spatial reorganization maximizes the use of available volume while maintaining functional integration, directly addressing the space utilization challenge without requiring excessive manufacturing complexity
2Volume of moving object
If the intersection angle between reference planes is 150 degrees or less, then compact arrangement and space efficiency are improved, but structural complexity increases
Solution Approach 1:
The patent specifies a quantitative parameter constraint (intersection angle ≤ 150 degrees) to optimize the spatial relationship between the two reference planes. This angular parameter control enables compact arrangement of power supply and circuitry while providing clear manufacturing guidance, balancing compactness requirements with manufacturing feasibility through defined geometric parameters
3Adaptability or versatility
If operating member is pivotally coupled to base member, then operational versatility is improved, but device complexity increases
Solution Approach 1:
The patent introduces a pivotally coupled operating member that enables dynamic movement and adjustment, transforming the static base member into a system with operational flexibility. This mechanical linkage allows the operating member to rotate or pivot relative to the base member, providing multiple operational positions and functions while adding only minimal structural complexity through the pivot connection
