Furniture Connecting Fitting with Adjustable Roller Chain Actuator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture connecting fittings struggle to provide a sturdy design capable of supporting heavy loads while maintaining a compact size.
Innovation Solution
The solution involves coupling a retaining device directly or indirectly to an actuator via a swivel lever and providing an adjustment device to alter the force transfer point of the retaining device within the roller chain, ensuring stability and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the furniture connecting fitting is designed to be sturdy for supporting heavy loads, then the load-bearing capacity is improved, but the overall size and complexity of the device increases
Solution Approach 1:
The patent combines the retaining device with the actuator into a single integrated unit, where the retaining device is coupled directly or indirectly to the actuator via a swivel lever. This merging of functions allows the device to maintain high load-bearing capacity while reducing overall structural complexity and space requirements.
Solution Approach 2:
The actuator serves multiple functions: it acts as both the driving mechanism for moving the roller chain and as part of the retaining device structure. The swivel lever couples both the actuating function and the retaining function, allowing a single component to perform multiple roles, thereby reducing the number of separate parts needed for heavy-load support.
2Volume of moving object
If the furniture connecting fitting is designed to be compact, then the overall size is reduced, but the load-bearing capacity and stability may be compromised
Solution Approach 1:
The retaining device is positioned within or alongside the actuator structure, with components nested together to minimize the overall footprint. The swivel lever connects the retaining device to the roller chain in a space-efficient manner, allowing the mechanism to maintain structural integrity for heavy loads while occupying minimal space within the furniture connecting fitting.
3Adaptability or versatility
If the force transfer point is fixed, then the structure is simpler, but the adaptability to different hatch or door weights is reduced
Solution Approach 1:
The adjustment device enables dynamic repositioning of the force transfer point on the roller chain according to the specific weight and requirements of the hatch or door. The adjustment element can be actuated to move the force transfer point to different positions on the roller chain, providing adaptability while maintaining a relatively simple structural design through standardized adjustment mechanisms.
