Front adjustment system for leveling feet for furniture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing front adjustment systems for furniture leveling feet face challenges in accessing and adjusting rear feet due to limited space beneath the furniture, requiring complex guides and transmission rods, which are costly and difficult to install.
Innovation Solution
A simplified front adjustment system using supporting and guiding units with elongated pass-through holes aligned with the rear feet's adjustment mechanism, allowing easy access and adjustment without separate transmission rods, suitable for various configurations and limited spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate supports and transmission rods are used to access rear feet, then accessibility to rear feet is improved, but device complexity increases
Solution Approach 1:
The patent combines the support function and guiding function into a single integrated unit that is already attached to the furniture bottom. This eliminates the need for separate transmission rods and guides, reducing device complexity while maintaining accessibility to the rear feet adjustment mechanism.
Solution Approach 2:
The supporting unit serves multiple functions simultaneously: it provides structural support, guides the adjustment tool, and enables access to the rear feet. This multi-functionality eliminates the need for dedicated transmission rods and separate guiding components.
2Ease of operation
If transmission rods and guides are installed, then adjustment of rear feet becomes possible, but manufacturing and assembly costs increase
Solution Approach 1:
By merging the support and guiding functions into one existing component, the patent eliminates the need for additional transmission rods and guides, thereby reducing manufacturing material costs and assembly operations.
Solution Approach 2:
The existing supporting unit attached to the furniture bottom is made to serve the additional function of guiding the adjustment tool. This self-service approach eliminates the need for separate dedicated guiding components, reducing both manufacturing and assembly costs.
3Ease of operation
If plaques with passages and housings are used, then transmission rods can be accommodated, but device complexity and cost increase
Solution Approach 1:
The patent extracts the guiding function from complex plaques with passages and housings and integrates it into the existing supporting unit. This eliminates the need for dedicated transmission rod accommodation structures, simplifying the overall design.
Solution Approach 2:
The supporting unit is designed to universally serve as both a structural support and a guiding mechanism for the adjustment tool, eliminating the need for separate plaques and housings designed specifically for transmission rods.
