Flexible Hinge Using Elastomer and Composite Fabric
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinges in electronic devices are often metallic and conductive, which can interfere with electronic signals and are not flexible enough to accommodate varying device configurations, limiting their functionality and aesthetics.
Innovation Solution
A flexible hinge composed of a first layer made from an elastomer, such as thermoplastic, thermoset, or synthetic rubber, combined with a second layer of composite fabric like Kevlar® or Cordura®, which is non-metallic and non-conductive, allowing for a non-interfering and adaptable connection mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional metallic hinges are used, then structural strength is ensured, but electronic signal interference occurs and flexibility is limited
Solution Approach 1:
The patent removes metallic components from the hinge structure entirely, extracting the harmful conductive property while retaining the mechanical coupling function through non-conductive polymer materials and fabric reinforcements
Solution Approach 2:
The hinge employs a composite structure combining polymer base material with fabric reinforcements (such as Kevlar® or Cordura®), creating a non-metallic composite that provides both structural strength and electrical non-conductivity, eliminating signal interference while maintaining mechanical performance
2Adaptability or versatility
If conventional metallic hinges are used, then structural strength is ensured, but flexibility and adaptability to varying configurations are reduced
Solution Approach 1:
The patent uses composite materials consisting of a polymer matrix combined with high-strength fabric reinforcements (Kevlar®, Cordura®, or other tear-resistant fabrics), which provide the necessary structural strength while maintaining flexibility and adaptability
Solution Approach 2:
The hinge design allows for variable thickness and material composition parameters throughout the structure, enabling optimization of both strength and flexibility in different regions of the hinge to accommodate varying device configurations
3Object-affected harmful factors
If non-metallic materials are used, then electronic signal interference is eliminated, but manufacturing complexity increases
Solution Approach 1:
The patent employs a layered construction with fabric reinforcements embedded within polymer layers, creating a flexible yet strong hinge structure that can be manufactured using conventional lamination and molding techniques, balancing non-metallic requirements with manufacturing feasibility
