Hinge Retainer With Eccentric Adjustment Disk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door hinge adjustment systems face issues with restricted use and potential slipping or twisting, especially with heavy doors, due to direct clamping and high surface pressure, which can lead to deformation and unreliable guide mechanisms.
Innovation Solution
The introduction of an adjustment device featuring an eccentric adjustment disk and shaft, allowing for secure clamping and adjustment of door hinges in multiple dimensions, including vertical movement, while preventing slipping and twisting through a polygonal socket and pin mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If direct clamping with a single clamping screw is used, then the structure is simple, but the frame part may slip or twist when adjusting heavy doors
Solution Approach 1:
The single clamping screw is divided into two separate clamping screws (first and second clamping screws) that clamp the frame part at different locations. This segmentation distributes the clamping force and prevents the frame part from slipping or twisting during adjustment, while maintaining structural simplicity.
2Device complexity
If a guide with a slot is used to prevent lateral displacement, then the guide structure is simple, but it cannot reliably prevent the frame part from twisting
Solution Approach 1:
The single guide slot is divided into two separate guide slots (first and second guide slots) positioned at different locations on the frame part. This segmentation provides multiple constraint points that work together to prevent both lateral displacement and twisting of the frame part during adjustment.
3Force
If the clamping screw touches the slanting bolt on a short line, then the clamping action is direct, but it leads to high surface pressure and risk of permanent deformation
Solution Approach 1:
The clamping force is segmented and distributed across two separate clamping screws acting at different locations on the frame part. This distribution reduces the surface pressure at each contact point, preventing permanent deformation while maintaining effective clamping action.
4Ease of operation
If the adjusting shaft passes through the adjustment disk eccentrically, then height adjustment is enabled, but the mechanism becomes more complex
Solution Approach 1:
The adjustment disk is designed to be rotatable relative to the adjusting shaft, creating a dynamic mechanism that enables height adjustment. The eccentric passage allows the adjustment disk to convert rotational motion into vertical displacement of the clamping plate, providing easy height adjustment while the modular design keeps the complexity manageable.
