Furniture Hinge Variable Spacer Element for Adjustable Opening Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges require multiple spacer elements for varying opening angles, leading to time-consuming replacements and storage of multiple spacers, which is inefficient and inconvenient.
Innovation Solution
A furniture hinge with a variably adjustable spacer element featuring wedge surfaces and a tool-accessible groove, allowing for continuous adjustment of the opening angle without needing multiple spacer elements, using locking elements and markings for easy setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple spacer elements with different opening angles are used, then the furniture hinge can be adapted to different opening angle requirements, but the device complexity and storage requirements increase
Solution Approach 1:
The spacer element is designed with multiple wedge surfaces having different wedge angles, allowing a single spacer element to provide multiple opening angle settings. This multi-functional design eliminates the need for multiple separate spacer elements, reducing complexity while maintaining adaptability for different opening angle requirements
Solution Approach 2:
The spacer element is made rotatable about its longitudinal axis, transforming it from a static component with fixed opening angle to a dynamic component that can be adjusted to different angles. This rotational capability allows the same physical component to adapt to various opening angle settings, replacing multiple static spacers
2Adaptability or versatility
If multiple spacer elements are used for different opening angles, then various opening angle settings are achieved, but the time required for replacement and adjustment increases
Solution Approach 1:
The rotatable spacer element allows quick adjustment between different opening angles by simply rotating the component, eliminating the time-consuming process of removing one spacer and installing another. The dynamic adjustment mechanism enables rapid reconfiguration without tool intervention for basic angle changes
Solution Approach 2:
Multiple wedge surfaces with different angles are pre-formed on the spacer element during manufacturing, so all desired opening angle settings are prepared in advance. This preliminary preparation of multiple angles on a single component eliminates the need for time-consuming selection and replacement operations during installation or adjustment
3Adaptability or versatility
If multiple spacer elements are stored for different opening angles, then all required opening angles are available, but the storage space and inventory requirements increase
Solution Approach 1:
A single spacer element incorporates multiple wedge surfaces with different wedge angles, making it a universal component that can provide multiple opening angle settings. This eliminates the need to store multiple separate spacer elements, reducing inventory requirements while maintaining all necessary opening angle options
Solution Approach 2:
Multiple spacer elements that would traditionally be stored separately are merged into a single integrated component with multiple functional surfaces. By combining several angle-setting functions into one physical object, the quantity of components to be stored and managed is reduced from multiple spacers to just one
