Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional ground path design is used, then the device structure remains simple, but the ground performance is insufficient and ESD risk increases
Solution Approach 1:
The patent uses a conductive resin part containing conductive particles (such as aluminum, copper, or nickel) mixed with resin material to create a composite grounding element. This composite structure provides both electrical conductivity for ESD protection and mechanical properties for structural support, resolving the contradiction between ground performance and device complexity.
Solution Approach 2:
The conductive resin part serves multiple functions simultaneously: it acts as a ground path for ESD protection, provides structural support in the folding area, and enables electrical connection between the set bracket and ground line. This multi-functionality improves ground performance without proportionally increasing device complexity.
2Adaptability or versatility
If the display panel is made flexible for folding, then adaptability improves, but structural stability and ESD protection become compromised
Solution Approach 1:
The patent applies different properties to different areas: the conductive resin part is specifically placed in the folding area where flexibility is needed, while maintaining sufficient electrical conductivity and structural stability locally. This localized application allows the display to fold without compromising overall structural stability or ESD protection.
3Reliability
If conductive particles are added to resin for ESD protection, then ground performance improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent controls the concentration, size, and distribution parameters of conductive particles within the resin to achieve optimal ESD protection. By carefully adjusting these parameters (such as particle concentration of 1-10 wt% and size of 1-100 micrometers), the invention maintains effective ground performance while keeping manufacturing processes manageable and precision requirements reasonable.
