Integrated Finger Guard for Swing Door Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing finger protection devices for swing doors are complex to install and require additional components, making them difficult to attach directly to door bands without adaptations.
Innovation Solution
A finger protection device with first and second protective agents that can be directly attached to the door bands, covering the gap between the door and the frame, eliminating the need for additional fastening agents and simplifying the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing finger protection devices are used, then gap coverage is achieved, but installation complexity increases and additional components are required
Solution Approach 1:
The protective means integrates the gap coverage function and the attachment function into a single unified component. The protective profile combines both the protective element and the attachment element, eliminating the need for separate fasteners and reducing installation complexity while maintaining reliable gap coverage
Solution Approach 2:
The protective means is designed with universal attachment capability that can be directly mounted to door hinges without requiring additional components. The attachment element provides multi-functional support for both the protective profile and the hinge mounting, simplifying the overall system
2Reliability
If additional fasteners are used for attachment, then secure mounting is achieved, but device complexity and installation difficulty increase
Solution Approach 1:
The attachment element is merged with the protective means, creating an integrated component that provides both protection and secure mounting in one element. This eliminates the need for separate fasteners and reduces installation steps while maintaining secure mounting through the integrated attachment design
3Adaptability or versatility
If protective devices are not directly attachable to hinges, then adaptability to different hinge types is achieved, but installation time and complexity increase
Solution Approach 1:
The attachment element is designed with universal compatibility to work with different hinge types directly. The protective means can be attached to various hinge configurations without requiring additional adapters or modifications, providing both adaptability and time-efficient installation through a single universal attachment mechanism
