Adjustable Door Clamp Spacer With Multi-Plane Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping devices for door leaves are complex to assemble and have limited adjustability in adjusting the distance between clamping surfaces to accommodate varying door leaf thicknesses, often requiring multiple components and complicated handling of spacer elements.
Innovation Solution
The clamping device features connecting sections with multiple support planes and a spacer element with counter planes that can be selectively positioned to adjust the distance between clamping surfaces, allowing for easy adjustment by rotating or inserting the spacer element into different positions, thereby simplifying assembly and increasing adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single spacer element is used to adjust the distance between clamping surfaces, then the number of components is reduced, but the adjustability to different door leaf thicknesses is limited
Solution Approach 1:
The spacer element is designed with multiple support planes at different axial positions along the screw axis, allowing it to be positioned in different receiving positions to dynamically adjust the distance between clamping surfaces. This dynamic positioning capability enables a single spacer element to accommodate various door leaf thicknesses without requiring multiple different spacer components.
Solution Approach 2:
The spacer element is segmented into multiple functional zones with support planes at different positions, each support plane corresponding to a specific receiving position. This segmentation allows the single spacer element to provide multiple adjustment options by selecting which support plane contacts the connecting section, thereby resolving the contradiction between component simplicity and adjustment versatility.
2Adaptability or versatility
If multiple connecting elements of different lengths are provided to adjust the distance between clamping surfaces, then adaptability to different door leaf thicknesses is improved, but assembly complexity and logistical effort increase
Solution Approach 1:
The single spacer element is designed to perform multiple functions by incorporating support planes at different axial positions. Instead of requiring multiple different connecting elements of various lengths, this universal spacer element can be positioned in different receiving positions to achieve the same adjustment effect, thereby simplifying assembly and reducing logistical requirements while maintaining full adaptability to different door leaf thicknesses.
3Ease of manufacture
If spacer elements are made structurally separate from side parts, then ease of assembly is improved, but handling complexity increases
Solution Approach 1:
The structurally separate spacer element acts as an intermediary component between the two side parts with connecting sections. This mediator approach allows the spacer to be independently manufactured and positioned, simplifying assembly while the multiple support planes integrated into the spacer provide built-in guidance for correct positioning, thereby reducing handling complexity despite the separate structure.
