Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a control device providing rotational damping into electrical switches often leads to assembly issues due to tolerance stack-up, resulting in positional deviation and increased production time and costs.
Innovation Solution
A control device with an elastic force-based rotational damping system, comprising an adjusting member with a rotating shaft and an elastic member, such as a compression spring, which is integrated into the base of the switch to prevent positional deviation and facilitate easier assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a control device providing rotational damping is integrated into the switch, then rotational damping control is achieved, but assembly problems occur due to tolerance stack-up causing positional deviation
Solution Approach 1:
The control device is separated from the switch assembly. The control device with rotating shaft and elastic member is mounted on the housing, while the switch is mounted separately on the circuit board. This segmentation eliminates the tolerance stack-up problem between the control device and switch, as they are no longer integrated together.
Solution Approach 2:
The elastic member acts as an intermediary between the rotating shaft and the housing. It provides rotational damping control through its elastic force while accommodating positional variations, thereby mediating between the control function and the assembly tolerance issues.
2Reliability
If a control device providing rotational damping is integrated into the switch, then rotational damping control is achieved, but production time and costs increase
Solution Approach 1:
By separating the control device from the switch, each component can be manufactured and prepared independently. The control device can be pre-assembled on the housing with the elastic member, and the switch can be separately mounted on the circuit board, significantly reducing assembly time and improving production efficiency.
Solution Approach 2:
The control device can be pre-installed on the housing before the switch assembly process. This preliminary action allows the elastic member to be pre-positioned and the rotating shaft to be pre-configured, eliminating the need for complex integration steps during final assembly.

Function Achieved in This Case
This solution reduces assembly time and costs while enhancing the quality of the manufacturing process and the finished product, allowing for fine-tunable and variable control of the switch.
Implementation Method 1
The elastic member is provided between the adjusting member and the base. The elastic force of the elastic member acts between the head portion of the adjusting member and the base to change the rotational damping to which the adjusting member is subjected when rotated with respect to the base.

AI summary
A control device capable of providing rotational damping through an elastic force is provided directly at the base of an electronic product and includes an adjusting member and an elastic member. The adjusting member is rotatably provided at the base. The adjusting member has a bottom portion corresponding to a switch provided in the base. The adjusting member further has a head portion outside the base. The elastic member is provided between the adjusting member and the base. The elastic force of the elastic member acts between the head portion of the adjusting member and the base to change the rotational damping to which the adjusting member is subjected.
