Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional torque modules exhibit poor friction performance, poor hovering effect, and large structure size, which limits the space for other components in devices like foldable mobile phones, reducing their performance and battery capacity.
Innovation Solution
A torque module design featuring a rotating shaft, blocking members, rotating assembly, sliding assembly, and elastic member, where the rotating assembly's rotation causes the sliding assembly to slide, and the elastic member compresses to provide friction and maintain the assembly's stationary state, reducing the overall size by optimizing component dimensions.

Engineering Contradiction Analysis
1Volume of moving object
If conventional torque module structures are used, then the hovering function is achieved, but the structure size is large and friction performance is poor
Solution Approach 1:
The torque module is divided into distinct functional components: a rotating assembly with rotating member, a sliding assembly with sliding member, and elastic members. This segmentation allows each component to be optimized independently for its specific function while collectively achieving compact size and improved friction performance.
Solution Approach 2:
The design incorporates dynamic interaction between rotating and sliding assemblies through elastic members. The elastic members dynamically adjust the friction force based on the rotation state, providing adaptive friction control that improves hovering performance while maintaining compact dimensions.
2Reliability
If conventional torque module structures are used, then the hovering function is achieved, but the friction performance is poor
Solution Approach 1:
Elastic members serve as intermediaries between the rotating assembly and sliding assembly. These elastic members transmit and modulate forces, enabling controlled friction interaction without requiring large contact surfaces or complex mechanical structures.
Solution Approach 2:
The friction force is controlled by changing the elastic force parameters of the elastic members. By adjusting the elastic properties and pre-compression forces, the friction torque can be precisely controlled to achieve optimal hovering performance in a compact design.
3Reliability
If larger torque module structure is used, then friction performance may be improved, but the space for other components is reduced
Solution Approach 1:
The sliding assembly is nested within the rotating assembly structure, with the sliding member positioned inside the rotating member. This nested configuration maximizes space utilization and allows the torque module to achieve high hovering performance in a compact footprint, leaving more space for other device components.
4Reliability
If the sliding assembly slides away from the rotating assembly, then the elastic member compresses to provide friction, but the structure requires precise positioning
Solution Approach 1:
The elastic members are pre-compressed during assembly to establish the initial friction force. This preliminary action ensures that the friction control mechanism is already engaged and positioned correctly before operation, reducing the need for high-precision positioning during manufacturing and assembly.

Implementation Method 1
a first elastic member, sleeved on the rotating shaft and disposed between the rotating assembly and the second blocking member; wherein a rotation of the rotating assembly enables the first mating portion and the second mating portion to cooperate with each other, and the sliding assembly is caused to slide in a direction close to or away from the rotating assembly; in condition of the sliding assembly sliding in the direction away from the rotating assembly, the first elastic member is in a compressed state
Implementation Method 2
the first mating portion and the second mating portion abut against each other, and the rotating assembly is caused to remain stationary relative to the sliding assembly in condition of the rotating assembly stopping rotating
