Simplified adjustable levelling system with joint for furniture and/or furnishing items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing levelling and joining systems for furniture are complex, require multiple elements, and often necessitate the use of transmission rods, making them difficult to assemble and store, and are not adaptable to different furniture widths or configurations.
Innovation Solution
A simplified adjustable levelling system with joints that uses firmly coupled foot units with internal height adjustment mechanisms accessible from the outside, eliminating the need for transmission rods and allowing easy assembly with standard tools, and is adaptable to various furniture configurations by using pass-through holes for tool access and a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional levelling and joining systems are used, then furniture can be levelled and parts joined, but the system becomes complex requiring multiple elements and transmission rods
Solution Approach 1:
The patent combines the levelling function and joining function into a single integrated foot unit. The foot unit includes both a levelling mechanism with height adjustment and a joining mechanism with blocking means, eliminating the need for separate levelling devices and joining systems. This merging reduces the number of elements from multiple separate components to a single unified device that performs both functions.
Solution Approach 2:
The patent extracts and eliminates the transmission rods from the system. Instead of using transmission rods to connect the height adjustment mechanism to the foot, the design allows direct access to the adjustment mechanism through the foot unit structure. This removal of unnecessary intermediate components simplifies the system while maintaining full functionality.
2Reliability
If multiple elements and transmission rods are used, then levelling and joining can be achieved, but assembly becomes difficult and storage space increases
Solution Approach 1:
By merging the levelling and joining mechanisms into a single foot unit, the patent reduces the number of assembly steps. The blocking means and height adjustment mechanism are pre-integrated, so the installer only needs to attach one component rather than assembling multiple separate elements. This directly improves assembly ease while maintaining full functionality.
Solution Approach 2:
The patent removes transmission rods from the assembly process. The height adjustment mechanism is designed to be accessible and operable without requiring transmission rods as intermediaries. This elimination of unnecessary components reduces both assembly complexity and the number of parts that need to be managed during installation.
3Reliability
If fixed levelling and joining systems are used, then specific furniture configurations can be served, but adaptability to different furniture widths and configurations is limited
Solution Approach 1:
The patent incorporates adjustable elements that allow the foot unit to adapt to different furniture configurations. The height adjustment mechanism and blocking means can be positioned and configured to suit various furniture widths and designs. This dynamic adjustability enables a single foot unit design to serve multiple furniture types while maintaining stable joining and levelling performance.
Solution Approach 2:
The foot unit is designed with universal applicability through its integrated design. The combination of levelling and joining functions in one unit, along with adjustable parameters, allows the same component to be used across different furniture types and configurations. This multi-functionality eliminates the need for multiple specialized components for different furniture designs.
