Front Foot Pass-Through Design for Rear Furniture Leveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current leveling systems for furniture face challenges in accessing and adjusting rear feet due to limited space beneath the furniture, requiring complex guides and transmission rods, which increase production and assembly costs and complicate the adjustment process.
Innovation Solution
A compact front regulation system that incorporates pass-through holes in the integrated connection of the front feet, allowing direct access and adjustment of rear feet using a long-stemmed screwdriver, eliminating the need for additional guides and transmission rods, and simplifying the adjustment process even in restricted spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate supports and transmission rods are provided to enable adjustment of rear feet, then accessibility to rear feet is improved, but device complexity and production costs increase
Solution Approach 1:
The patent merges the functions of separate supports and transmission rods into the front feet structure itself. The front feet are designed with internal cavities that directly house the transmission rods, eliminating the need for separate support structures. This integration maintains accessibility to rear feet while reducing the total number of components and simplifying the overall device structure.
Solution Approach 2:
The front feet are designed to serve multiple functions: they provide structural support, contain the transmission rods for adjusting rear feet, and offer access pathways for adjustment tools. This multi-functionality eliminates the need for dedicated separate supports, reducing device complexity while maintaining operational ease.
2Manufacturing precision
If separate supports with guides are arranged to support transmission rods, then adjustment precision is improved, but ease of manufacture deteriorates
Solution Approach 1:
The guide structures are integrated directly into the front feet rather than being separate components. The front feet include internal guide walls and cavities that form the transmission rod supports as part of the main structure, eliminating the need for separate guide components and simplifying assembly while maintaining adjustment precision.
3Reliability
If plaques with passages and housings are provided for transmission rods, then transmission rod support is improved, but device complexity and costs increase
Solution Approach 1:
The plaque structure is merged with the front feet. The front feet are designed with integrated cavities and passages that directly support the transmission rods, eliminating the need for separate plaque components. This integration maintains reliable transmission rod support while reducing the number of additional elements and overall device complexity.

AI summary
A compact front regulation system for leveling feet of furniture pieces having a bottom and shoulders includes, in combination, at least one front foot and at least one rear foot, the at least one rear foot having a regulation mechanism in height which is accessible from the outside and which can be maneuvered using a regulation tool. The at least one front foot has a pass-through hole for the regulation tool of the rear foot, the pass-through hole acting as a support and a guide for the regulation tool.
