Locking Fitting Control Device Stepped Hanging Rims
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking fitting control devices for door or window carpentry face challenges in securely fixing the control device within the carpentry profile, particularly due to variations in the thickness of the profile's wall, leading to potential loosening or loss of screws and increased complexity.
Innovation Solution
The control device incorporates at least two hanging organs acting in opposition, with at least one of the hanging means defined by a succession of hanging rims arranged in a staircase configuration, which extends under the application face of the housing at distinct distances, effectively gripping the profile's wall and maintaining the control device's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixing screws are used to ensure pinching effect on the profile wall, then the control device is securely fixed, but the screws risk loosening or loss and installation is time-consuming
Solution Approach 1:
The invention extracts the fixing function from traditional screws and replaces it with integrated fixing members that are part of the housing structure. The fixing members include engagement elements that directly engage with the profile wall, eliminating the need for separate fixing screws and their associated installation time and reliability issues.
Solution Approach 2:
The fixing members are designed to automatically engage and secure the control device to the profile wall without requiring additional fastening operations. The engagement elements self-position and self-secure through the housing structure, making the fixing process self-service and eliminating manual screw tightening.
2Reliability
If traditional fixing members are used, then the control device can be fixed, but the structure becomes complex with mobile fixing organs
Solution Approach 1:
The invention merges the fixing members with the housing structure, creating an integrated assembly where the fixing elements are built into the housing rather than being separate mobile components. This integration simplifies the overall structure while maintaining reliable fixing through the engagement elements that directly interact with the profile wall.
3Manufacturing precision
If the control device is designed for specific profile wall thicknesses, then fixing is optimized, but adaptability to varying thicknesses is reduced
Solution Approach 1:
The fixing members are designed with engagement elements that can adapt to different profile wall thicknesses. The housing structure accommodates varying thicknesses through the geometric configuration of the fixing members, allowing the same control device to be universally applied to profiles with different wall thicknesses while maintaining precise fixing.
