Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair curlers with automatic rotation mechanisms are expensive and inconvenient for manual control of curling toggle direction, lacking flexibility in one-way rotation control.
Innovation Solution
A hair curler with a button for manual control of forward and reverse rotation, featuring a manual rotating mechanism with a control button, commutation sliding block, and transmission assembly, allowing users to manually control the direction of the curling toggle through a commutation sliding block and transmission assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an automatic hair curler with motor-driven rotation control is used, then the automation level and curling convenience are improved, but the device complexity and cost increase
Solution Approach 1:
The patent replaces the motor-driven automatic rotation system with a manual mechanical operation system. Users directly rotate the curling toggle by hand, and the heating passage rotates through mechanical transmission components (transmission assembly, commutation sliding block, transmission teeth) engaged with the curling toggle. This eliminates the need for motors and complex control circuits while maintaining the curling function.
2Device complexity
If a rotating wheel with gear ring is used for manual rotation control, then the cost is reduced, but the ease of operation deteriorates due to difficulty in manual curling
Solution Approach 1:
The patent makes the curling toggle dynamically controllable by allowing users to rotate it freely in different directions. The heating passage is mechanically coupled to the curling toggle through transmission teeth, enabling the heating passage to rotate synchronously with the curling toggle. This dynamic mechanical linkage provides flexible and easy manual operation for curling hair.
3Ease of operation
If a control button for one-way rotation is implemented, then the ease of operation is improved, but the adaptability deteriorates due to inability to control rotation direction
Solution Approach 1:
The patent implements a dynamic bidirectional rotation control system where the heating passage can rotate in both directions (clockwise and counter-clockwise) through mechanical transmission. The commutation sliding block and transmission assembly enable the heating passage to change rotation direction by engaging transmission teeth with the curling toggle. This provides adaptable control for different curling needs while maintaining ease of manual operation.

AI summary
A hair curler with a button for manual control of forward and reverse rotation includes a host machine housing, a heating passage, a manual rotating mechanism, and a curling toggle. The manual rotating mechanism includes a control button, a commutation sliding block, which are respectively arranged on the host machine housing, and a transmission assembly arranged inside the host machine housing. The commutation sliding block is connected to the transmission assembly. The transmission assembly is connected to the control button through engagement of transmission teeth. The curling toggle has one end that is connected to the transmission assembly through engagement of transmission teeth, so as to rotate under the control of the control button.
