Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional power supply rails are introduced to power multiple isolated electric power supplies, then the power distribution capability is improved, but the occupied surface area of the circuit increases
Solution Approach 1:
The patent introduces a third dimension by stacking conductive tracks in multiple levels (first level and second level). The first grid uses conductive tracks in both the first and second levels, while the conductive rail uses conductive tracks in the first level spaced apart to allow current flow. This vertical stacking enables additional power supply rails without increasing the horizontal surface area occupied by the circuit.
2Area of stationary object
If conductive tracks are arranged in multiple levels to reduce surface area, then the surface area efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent segments the conductive structure into distinct functional components: a first grid with conductive tracks in two levels, and a conductive rail with spaced conductive tracks in the first level. This segmentation allows each component to be manufactured and configured independently, simplifying the overall manufacturing process despite the multi-level arrangement.
Solution Approach 2:
The conductive tracks in the first level serve multiple functions: they form part of the first grid for powering the first circuit, and they also form the conductive rail for powering the second circuit. This multi-functionality reduces the total number of conductive track layers needed, thereby reducing manufacturing complexity while maintaining surface area efficiency.
