Sliding Door Fitting With Inclined Axis For Secure Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door fittings for shower partitions face challenges in maintaining adjusted height positions over time due to misalignment of adjusting screws under frequent use, making it difficult to access and leading to incorrect positioning and potential damage.
Innovation Solution
A fitting with an axial locking device and an inclined adjusting axis that absorbs forces better, combined with a compact design featuring a rotatable adjusting screw and grub screw locking mechanism, ensures the adjusted position is locked and protected from environmental contaminants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vertical adjustment device is used, then the structure is simple, but the forces acting on it are not well absorbed and it is difficult to access during adjustment
Solution Approach 1:
The adjustment device is reoriented from a vertical alignment to an inclined alignment, changing the spatial dimension of force application. The adjustment axis is now inclined relative to the longitudinal extent of the guide profile, allowing forces to be better absorbed and distributed while improving accessibility for assembly personnel.
2Ease of operation
If the adjustment device is easily accessible, then adjustment is simple, but the set position cannot be maintained over time due to misalignment
Solution Approach 1:
The adjustment mechanism is divided into two independent functional components: the adjusting device for position modification and the locking device for position maintenance. The locking device can be operated independently to secure the adjusting screw at the desired position, ensuring long-term position maintenance while keeping the adjustment process simple.
Solution Approach 2:
The locking device is designed to be activated after adjustment to pre-secure the position before any misalignment can occur during subsequent sliding door operations. This preliminary locking action prevents future position drift.
3Reliability
If a locking device is added, then position maintenance is improved, but the device complexity increases
Solution Approach 1:
The locking device is integrated into the existing suspension structure, with the locking screw threaded into the suspension body. This merging approach allows the locking function to be added without requiring a completely separate mechanism, thus improving position stability while minimizing the increase in overall device complexity.
