Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional carrying device design is used, then the receiving device can be mounted on the vehicle, but mechanical stability and force transmission are insufficient, leading to reduced space and potential mechanical collisions
Solution Approach 1:
The patent introduces slanted edge elements that extend in multiple dimensions (vertically, laterally, and at angles) rather than simple horizontal placement. This multi-dimensional configuration provides mechanical stability through vertical and angular support while the slanted design efficiently transmits forces, allowing sufficient internal accommodation space without requiring excessive horizontal clearance that would lead to mechanical collisions.
2Reliability
If the carrying device is designed with adequate mechanical stability, then operational reliability is improved, but device complexity increases
Solution Approach 1:
The carrying device is segmented into distinct functional components: a base structure, multiple slanted edge elements (first and second edge elements), and magnetically conductive elements. Each segment performs a specific function - the base provides support, the slanted edge elements provide mechanical stability and force transmission, and the magnetically conductive elements enhance magnetic core effectiveness. This segmentation allows for simplified manufacturing and assembly while maintaining high operational reliability.
3Use of energy by moving object
If magnetically conductive elements are added to maximize magnetic core area, then inductive power transfer efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The magnetically conductive elements are integrated with the slanted edge elements, merging the mechanical support function with the magnetic field enhancement function. This combination allows the same structural components to serve dual purposes - providing mechanical stability through their slanted configuration while simultaneously maximizing magnetic core area through the attached magnetically conductive elements. This merging approach improves inductive power transfer efficiency without proportionally increasing manufacturing complexity.
