Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If side frames are disposed to encase interior display panels, then protection is achieved, but appearance is degraded due to oversized frames
Solution Approach 1:
The patent extracts the protective function from the traditional side frame structure and relocates it to the bendable device edges. The flexible substrate with conductive layers provides protection without requiring visible external frames, thus maintaining aesthetic appearance while achieving encasement protection.
Solution Approach 2:
The patent employs flexible substrates and thin conductive films to provide protection. These thin, flexible structures replace bulky side frames, offering the necessary protective function while being visually unobtrusive and maintaining device aesthetics.
2Strength
If traditional frame structure is used, then protection is provided, but electrostatic discharge failure occurs due to ungrounded external electrostatic charge
Solution Approach 1:
The patent introduces a conductive layer as an intermediary between the flexible substrate and the external environment. This conductive layer acts as a mediator that captures external electrostatic charges and directs them to ground, preventing ESD damage to internal components while maintaining the protective function.
Solution Approach 2:
The flexible substrate structure integrates the grounding function directly into its construction. The conductive layers within the flexible substrate automatically discharge electrostatic charges without requiring external intervention or additional protective components, making the system self-protecting against ESD.
