Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustment tools for base feet of furniture, such as kitchen cabinets, are difficult to handle due to small toothed surfaces and require two-handed operation, making precise adjustments challenging, especially in hard-to-reach areas.
Innovation Solution
An adjustment tool with an electric motor drive connected to a measuring and control device that automatically adjusts the angle of inclination, allowing one-handed operation and preventing decoupling, featuring a larger gear coupling area and optional dual gear wheels driven by a worm wheel for enhanced precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a manual adjustment tool with a small gear wheel is used, then the tool can be simple in structure, but the toothed surface is very small causing easy decoupling and requiring two-handed operation
Solution Approach 1:
The patent replaces the manual mechanical operation system with an automated electromechanical system. An electric motor drive unit with a motor shaft replaces the need for manual two-handed operation, converting rotational motion to adjust the base foot height automatically. This substitution eliminates the handling difficulty while maintaining structural simplicity through modular design.
Solution Approach 2:
The adjustment tool is designed to perform the adjustment operation autonomously once activated. The electric motor automatically executes the height adjustment without requiring continuous manual intervention or two-handed operation. The system serves itself by converting electrical energy to mechanical motion independently, freeing the user from direct operational complexity.
2Volume of moving object
If the gear wheel has a small toothed surface, then the device remains compact, but even small handle movements cause decoupling from the adjustment part
Solution Approach 1:
The patent eliminates the mechanical coupling between a small gear wheel and the adjustment part by replacing it with an electric motor drive system. The motor directly or indirectly drives the adjustment mechanism through controlled rotational motion, removing the need for manual handle operations that cause decoupling. This substitution maintains compactness while dramatically improving coupling stability through precise motor control.
3Device complexity
If manual two-handed operation is required, then the device can be simple, but precise adjustment is difficult especially in hard-to-reach areas
Solution Approach 1:
The patent replaces manual two-handed mechanical operation with an electric motor drive system that provides controlled, precise rotational motion. The motor enables accurate height adjustment without requiring the user to physically manipulate handles in hard-to-reach areas. This substitution maintains operational simplicity through remote or automated control while achieving high adjustment precision through motor control mechanisms.
4Manufacturing precision
If an electric motor drive is added to enable automatic adjustment, then adjustment precision can be improved, but device complexity increases
Solution Approach 1:
The patent introduces an electric motor drive unit to replace manual mechanical operation, achieving precise automatic height adjustment. The motor converts electrical energy to controlled rotational motion for accurate positioning. While this adds some complexity, the design mitigates it through modular integration, using the motor shaft directly to drive the adjustment mechanism, thereby maintaining relatively simple overall device structure while gaining precision.
