Hidden Hanging Bracket Slide Structure for Heavy Load Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hidden hanging brackets often fail to withstand significant loads due to weak slides and guides, leading to potential cupboard collapse and associated risks of damage or injury.
Innovation Solution
A hidden hanging bracket with a structurally reinforced slide system, produced from a single metallic piece with specific geometric configurations and threading, that provides enhanced stability and resistance to stress, incorporating anti-disengagement mechanisms and optimized hole configurations for improved load-bearing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional slides and guides are used in hidden hanging brackets, then the device complexity is reduced and ease of manufacture is improved, but the strength and reliability deteriorate under significant loads
Solution Approach 1:
The patent merges the slide and guides into a single integrated component made from one metallic piece. The slide incorporates guide surfaces directly on its lateral faces, eliminating the need for separate guide components. This integration maintains strength under significant loads while simplifying the overall device structure and manufacturing process.
Solution Approach 2:
The slide is constructed as a composite structure combining a metallic body with integrated guide surfaces. The use of a single metallic piece with strategically positioned guide surfaces creates a composite-like functionality that provides both strength and guiding capability without requiring multiple separate components.
2Reliability
If the slide structure is simplified for ease of manufacture, then production cost and complexity are reduced, but the reliability and resistance to stress deteriorate under extreme loads
Solution Approach 1:
By combining the slide and guide functions into a single metallic piece, the invention improves reliability under extreme loads while maintaining manufacturing simplicity. The integrated design eliminates weak points at connection interfaces between separate components, reducing the risk of breakage while requiring only basic metal forming and threading operations.
3Strength
If conventional threaded holes are used in the slide, then ease of manufacture is improved, but the strength and anti-disengagement capability deteriorate under significant loads
Solution Approach 1:
The slide features locally optimized hole configurations with specific geometric shapes and threading patterns at critical locations. The holes are designed with enhanced threading and positioning features that provide superior anti-disengagement capability while maintaining manufacturability through standard machining operations. This localized quality enhancement addresses high-stress areas without complicating the overall manufacturing process.
