Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging is implemented, then charging convenience is improved, but heat generation increases
Solution Approach 1:
The patent divides the charging system into multiple independent charging units (first charging unit and second charging unit) with separate conductive lines. This segmentation allows heat to be distributed across multiple paths rather than concentrated in a single path, reducing peak temperature in any one location while maintaining wireless charging convenience.
2Productivity
If multiple conductive lines are used to reduce resistance, then charging efficiency is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple conductive lines (first conductive line and second conductive line) into a unified structure where they run parallel and then converge. This merging approach reduces overall resistance by providing multiple current paths while consolidating the design into a manageable configuration that doesn't excessively increase device complexity.
Solution Approach 2:
The conductive lines are arranged in a three-dimensional configuration within the device, running through different spatial paths before converging. This dimensional arrangement allows multiple conductive paths to coexist without excessive planar complexity, reducing resistance while maintaining a compact design.
3Temperature
If charging units are controlled to manage heat, then temperature control is improved, but control system complexity increases
Solution Approach 1:
The controller monitors temperature conditions and uses feedback to selectively activate or deactivate charging units. When temperature exceeds thresholds, the controller adjusts which charging unit operates, creating a closed-loop control system that manages heat while maintaining relatively simple control logic based on temperature feedback.
