Rotating Intrusion Switch Module for Drawer Tolerance and Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intrusion-detection switches in data storage devices often become ineffective due to assembly tolerance issues and are prone to false triggering or damage from collisions, compromising the integrity of drawer operations.
Innovation Solution
A rotating module is integrated with an intrusion-detection switch to extend its operating range and absorb impact forces, using a spring mechanism to maintain contact and prevent over-compression, thereby enhancing the switch's durability and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional intrusion-detection switch is used in a drawer assembly, then intrusion detection function is provided, but the switch becomes ineffective due to assembly tolerance exceeding its operating range
Solution Approach 1:
The patent applies the dynamics principle by making the rotating module rotatable relative to the drawer. The rotating module can dynamically adjust its position through rotation to maintain contact with the intrusion-detection switch despite drawer position variations, thereby extending the effective operating range while maintaining reliable detection
Solution Approach 2:
The patent changes the positional parameter of the rotating module through rotational movement. By allowing the module to rotate to different angular positions, the system adapts to varying drawer assembly positions, effectively extending the switch's operating range beyond its original fixed limitations
2Reliability
If an intrusion-detection switch is installed in a drawer, then intrusion detection is enabled, but the switch is prone to false triggering or damage from collisions during usage or transportation
Solution Approach 1:
The rotating module serves as an intermediary between the drawer structure and the intrusion-detection switch. It absorbs and isolates collision forces from direct transmission to the switch, preventing damage and false triggering while maintaining accurate intrusion detection capability
Solution Approach 2:
The rotating module provides beforehand cushioning by being positioned to absorb impact forces before they reach the intrusion-detection switch. This protective arrangement prevents damage and false triggering from collisions during usage or transportation
3Ease of manufacture
If the drawer assembly uses standard tolerance ranges, then manufacturing is simplified, but the intrusion-detection switch operating range is insufficient
Solution Approach 1:
The rotating module introduces dynamic adaptability to compensate for assembly tolerances. Instead of requiring tight tolerance control, the rotatable module can adjust its position to accommodate standard tolerance ranges, simplifying manufacturing while ensuring reliable switch operation
Solution Approach 2:
The system changes the positional parameter of the rotating module through rotation to accommodate variations within standard assembly tolerances. This allows manufacturing with conventional tolerance ranges while maintaining sufficient operating range for the intrusion-detection switch
