Engineering Contradiction Analysis
1Area of stationary object
If a sliding mechanism is used to expand the display area, then the display area is increased, but foreign matter infiltration and noise interference occur
Solution Approach 1:
A conductive structure is introduced as an intermediary element between the first and second structures. This conductive structure serves multiple functions: it maintains electrical connection (grounding) between the sliding parts, prevents foreign matter infiltration by filling gaps, and reduces noise interference through proper electrical shielding. The conductive structure acts as a mediator that enables the sliding mechanism to function while mitigating its harmful effects.
2Reliability
If conductive structures are added to prevent foreign matter infiltration and reduce noise, then reliability is improved, but device complexity increases
Solution Approach 1:
The conductive structure is designed to perform multiple functions simultaneously: it provides electrical grounding, prevents foreign matter infiltration, and reduces noise interference. By making the conductive structure multi-functional, the patent avoids adding separate components for each function, thereby improving reliability without proportionally increasing device complexity. The same structural element serves multiple protective and functional purposes.
