Furniture fitting or building fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture fittings suffer from mechanical overload leading to thread stripping or breakage of adjustment wheels, limiting their durability and functionality.
Innovation Solution
Incorporation of a separate stop mechanism, such as a counter-stop, to limit the rotational movement of adjusting elements, providing defined feedback on adjustment range and reducing the risk of damage to the adjustment elements and threads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional fitting with separate fastening elements and adjustment mechanisms is used, then adjustability and connection strength are improved, but device complexity and number of parts increase
Solution Approach 1:
The patent combines multiple functional elements (fastening, adjustment, connection) into a single integrated fitting component. The fitting comprises a body with integrated fastening elements and adjustment mechanisms, eliminating the need for separate parts while maintaining adjustability and connection strength functions.
Solution Approach 2:
The fitting is designed as a multi-functional component that simultaneously provides fastening, adjustment, and connection functions. The single fitting structure can perform multiple operations that traditionally required separate dedicated components, reducing overall device complexity.
2Strength
If a traditional fitting with multiple separate components is used, then connection strength is improved, but ease of assembly and disassembly deteriorates
Solution Approach 1:
By merging fastening and adjustment functions into a single integrated fitting body, the number of assembly steps is reduced. The fitting can be installed and adjusted as one unit rather than assembling multiple separate components, improving ease of installation while maintaining connection strength through the integrated design.
3Device complexity
If a fitting with integrated fastening elements and adjustment mechanisms is used, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
While the fitting is integrated, the design incorporates modular functional zones within the single body structure. The fastening elements, adjustment mechanisms, and connection points are segmented as distinct functional regions, allowing for standardized manufacturing of each zone while maintaining overall integration, thus balancing manufacturing precision requirements with device simplicity.
4Ease of operation
If adjustment mechanisms are integrated into the fitting body, then ease of adjustment is improved, but device complexity increases
Solution Approach 1:
The adjustment mechanism is designed to be self-contained within the fitting body, allowing users to perform adjustments directly on the installed fitting without requiring external tools or additional components. This self-service capability improves ease of adjustment while the integration keeps the overall device complexity manageable.
