Furniture lifting system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lifting mechanisms face challenges when lowering objects onto a floor or support base, requiring precise installation and potential additional adjustment mechanisms to ensure proper support, leading to increased complexity and cost.
Innovation Solution
A lifting system that allows the item of furniture to 'float' between raised and lowered positions, with moving members that support the item until it is fully supported by the floor or support base, then release, accommodating variations and imprecision without complex adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lifting mechanism is rigidly attached to the item of furniture, then the item can be precisely positioned, but the mechanism experiences increased wear and tear when lowered too far and requires complicated adjustment mechanisms to accommodate installation variations
Solution Approach 1:
The patent transitions from a rigid fixed connection to a dynamic movable connection between the item of furniture and lifting mechanism. The item is allowed to move vertically on the lifting mechanism through a movable connection that maintains support while accommodating position variations, eliminating the need for complex adjustment mechanisms and reducing wear on the lifting mechanism.
2Reliability
If the lifting mechanism is mounted in the exact location required for proper support, then the item is properly supported on the floor, but the installation process becomes time consuming and unforgiving with little or no room for error
Solution Approach 1:
The patent changes the positional parameter relationship between the lifting mechanism and item of furniture from fixed to movable. This allows the item to self-adjust its position relative to the lifting mechanism, accommodating installation variations without requiring precise mounting location or time-consuming adjustment procedures.
3Reliability
If additional adjustment mechanisms are provided to accommodate installation variations, then the item can be properly supported, but the manufacturing cost and installation time increase
Solution Approach 1:
The patent extracts the adjustment function from separate mechanical adjustment mechanisms and integrates it into the basic movable connection structure. The movable connection itself provides the adjustment capability needed to accommodate installation variations, eliminating the need for additional complex adjustment components and reducing manufacturing costs.

AI summary
A structure includes an item of furniture coupled to a lift system. The lifting system is configured to move the item of furniture vertically along a path between a lowered position and a raised position. The item of furniture is coupled to the lifting system in a manner that allows the item of furniture to move upward along the path when the lifting system is stationary. When the item of furniture is in the lowered position, it is supported on the floor of the structure. This configuration allows the item of furniture to float relative to the lifting system so that when the item of furniture reaches the lowered position, it is supported only by the floor and not the lifting system.
