Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display panel with metallic material is added to provide displaying function, then the displaying function is improved, but the temperature increases due to heat absorption affecting performance
Solution Approach 1:
The patent removes the problematic metallic material from the conductive layer of the display panel, extracting the heat absorption issue while retaining the essential electrical conductivity function through alternative non-metallic conductive materials
Solution Approach 2:
The patent changes the material parameter of the conductive layer from metallic to non-metallic conductive materials, which fundamentally alters the thermal properties while maintaining electrical functionality, thereby reducing heat absorption during charging
2Temperature
If the display panel and charging circuit are separately arranged to avoid heat issues, then the temperature control is improved, but the device volume increases
Solution Approach 1:
The patent merges the display panel and charging circuit into a single overlapping structure, combining functions that were previously separated, thereby reducing overall device volume while managing heat through non-metallic conductive materials
Solution Approach 2:
The patent transitions from a horizontal separation arrangement to a vertical overlapping arrangement, utilizing the vertical dimension to stack the display panel and charging circuit, thereby reducing the horizontal footprint and overall device volume
3Temperature
If conventional charging device design is used without display panel, then the temperature control is improved, but the displaying function and interaction capability are lost
Solution Approach 1:
The patent makes the display panel multi-functional by integrating it with the charging circuit, enabling it to serve both as a display interface for user interaction and as part of the charging system through its conductive layer, thereby adding displaying function without compromising temperature control
