Access Panel Travel-Stop Bracket for Door Detachment Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional access panels suffer from the issue of the door detaching from the fixed frame during opening, leading to potential damage and safety hazards due to accidental misalignment of lateral appendages, necessitating frequent reattachment and posing risks of injury.
Innovation Solution
The access panel incorporates travel-stop brackets with elastic clips and retaining plates to secure lateral appendages, ensuring they remain attached to the fixed frame during movement, preventing detachment and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is allowed to tilt freely during opening, then the door can be easily opened, but the lateral appendages may detach from the fixed frame causing the door to fall
Solution Approach 1:
The travel-stop bracket applies preliminary anti-action by providing a stop edge that prevents the lateral appendage from moving beyond a predetermined position during door opening. This counteracts the tendency of the appendage to detach due to misalignment, allowing free tilting motion while preventing harmful detachment.
2Reliability
If travel-stop brackets are added to prevent detachment, then door safety is improved, but device complexity increases
Solution Approach 1:
The travel-stop bracket is segmented into distinct functional elements: a body portion that attaches to the fixed frame, a stop edge that limits appendage travel, and coupling means that connect to the lateral appendage. This segmentation allows each element to perform its specific function independently while maintaining overall simplicity.
Solution Approach 2:
The travel-stop bracket acts as an intermediary element between the fixed frame and the lateral appendage. It mediates the interaction by providing a controlled connection that allows necessary motion while preventing harmful detachment, thus adding minimal complexity while significantly improving reliability.
3Reliability
If the lateral appendages are secured to prevent detachment, then safety is improved, but assembly time increases
Solution Approach 1:
The coupling means of the travel-stop bracket employs self-service through elastic clips that automatically engage with the lateral appendage during assembly. The elastic nature of the clips allows them to snap into place without requiring additional fastening operations, reducing assembly time while ensuring reliable attachment.
