Optical Module Bracket With Conductive Layers For Detachment Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical modules lack a design to detect when the optical component detaches from the bracket, leading to potential damage due to shaking or collision, as they do not have a mechanism to monitor the detachment of the optical component.
Innovation Solution
A bracket with conductive layers on its surface and grooves, where a light-transmissive conductive layer on the optical component is electrically connected to the conductive layers, allowing the circuit to detect detachment and trigger protection measures by forming a protection circuit that shuts down the chip component when the optical component is loosened or detached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical module uses a simple bracket structure without detection mechanisms, then the device complexity is reduced and manufacturing cost is lowered, but the reliability deteriorates because the optical component can detach without detection causing damage
Solution Approach 1:
The bracket combines multiple functions into a single structure: mechanical support function and electrical detection function. The conductive layers are integrated into the bracket body, allowing it to both hold the optical component and detect its presence through electrical connection changes when detachment occurs.
Solution Approach 2:
The bracket serves multiple purposes: it provides mechanical support for the optical component, acts as an electrical connection pathway through its conductive layers, and functions as a detection mechanism by monitoring the electrical state to determine component attachment status.
2Reliability
If the optical module includes a detection mechanism using conductive layers, then the reliability improves by detecting detachment, but the manufacturing precision requirement increases due to the need for precise conductive layer configuration
Solution Approach 1:
The bracket's conductive layers automatically perform the detection function without requiring separate detection components. The electrical connection state changes self-indicatively when the optical component detaches, eliminating the need for complex external sensing systems and reducing manufacturing precision requirements.
3Reliability
If the optical component is secured firmly in the bracket, then the reliability improves by preventing detachment, but the ease of operation deteriorates because the optical component cannot be easily replaced or adjusted
Solution Approach 1:
The bracket provides dynamic securing: the optical component is held firmly in the installed state through the conductive connection, but can be easily removed when needed. The detection mechanism monitors the transition between attached and detached states, allowing reliable operation during use while facilitating easy maintenance and replacement.
