Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clutches that implement engaging and disengaging functions using magnetic components face challenges such as large volume and demagnetization issues, while electromagnetic clutches are difficult to miniaturize.
Innovation Solution
A clutch design featuring a drive force receiving part, a clutch controlling part with multiple positions for engaging and disengaging, and a drive force outputting part, which uses a mechanical mechanism to switch between engaging and disengaging positions without magnetic components, allowing for effective drive force transmission in both directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electromagnetic principle or magnetic component is used to implement engaging and disengaging functions, then the clutch structure is simple and magnetism is easier to control, but the volume is large and difficult to shrink
Solution Approach 1:
The patent replaces the electromagnetic or magnetic component-based clutch system with a purely mechanical clutch mechanism. The mechanical clutch uses a clutch piece that can be positioned at different locations (first location for engagement, second location for disengagement) through mechanical actuation, eliminating the need for electromagnetic coils, magnets, or magnetic beads. This substitution reduces the volume while maintaining the engaging and disengaging functions.
2Device complexity
If magnetic component is used to implement engaging and disengaging functions, then the structure is simple, but demagnetization of the magnetic component occurs
Solution Approach 1:
The patent extracts and removes the magnetic component from the clutch system entirely, replacing it with a mechanical engagement mechanism. The clutch piece engages and disengages through mechanical positioning rather than magnetic attraction, eliminating the demagnetization problem while keeping the structure relatively simple.
3Ease of operation
If electromagnetic device is used to implement engaging and disengaging functions, then the engaging and disengaging functions are achieved, but the volume is large and difficult to miniaturize
Solution Approach 1:
The patent substitutes the electromagnetic device with a compact mechanical clutch mechanism. The mechanical system uses a clutch piece that can be positioned at different locations through mechanical actuation, achieving the same engaging and disengaging functions in a much smaller volume suitable for miniaturization.

AI summary
The present invention discloses a clutch, a motor device and a curtain control device. The clutch comprises: a drive force receiving part; a clutch controlling part which is disposed at a side of the drive force receiving part which comprises a first control piece, connected to the drive force receiving part, and a first direction driving position and a first direction disengaging position connected to the first direction driving position are disposed at a side of the first control piece away from the drive force receiving part; a clutch piece, located at the first direction driving position or the first direction disengaging position; and a second control piece, sleeved around the first control piece and the clutch piece; a drive force outputting part. The embodiments of the present disclosure effectively solve the problems resulting from the use of magnetic separation in realizing engaging and disengaging functions of an existing clutch.
