Solution Overview
Problem
In high-density optical connector arrangements, conventional dust-proof devices are inconvenient to remove due to limited operation space, especially in the middle area, causing user effort and inconvenience.
Innovation Solution
A dust-proof device with a flexible and swingable handle structure that deforms to create an operation space for removal, allowing the device to be pulled out and then return to its original position using accumulated restoring force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the space between adjacent coupling portions is reduced to achieve high-density arrangement, then the number of optical connectors that can be accommodated increases, but the operation space for removing dust-proof devices becomes limited and inconvenient
Solution Approach 1:
The dust-proof device incorporates a flexible arm that can dynamically change its configuration. When removal force is applied, the flexible arm deforms and swings outward, temporarily increasing the operation space. After removal, the flexible arm returns to its original position due to elastic restoring force. This dynamic behavior allows the device to adapt to the limited space constraints while enabling easy removal operations.
Solution Approach 2:
The flexible arm changes its physical state between a compact configuration (when installed) and an expanded configuration (when being removed). This parameter change in shape and position allows the dust-proof device to fit in tight spaces during normal operation while creating sufficient space during the removal process, effectively resolving the contradiction between high-density arrangement and ease of operation.
2Stability of the object's composition
If a rigid dust-proof device is used in high-density arrangement, then the structure is simple and stable, but the user must exert significant effort to remove it due to limited operation space
Solution Approach 1:
The dust-proof device transitions from a static rigid structure to a dynamic flexible structure. The flexible arm maintains structural stability during installation and normal operation, but can dynamically deform during removal to reduce the effort required. This dynamic characteristic allows the device to satisfy both structural stability and ease of operation requirements.
Solution Approach 2:
The flexible arm undergoes parameter changes in shape and position when force is applied, transforming from a compact stable state to an expanded removal state. This parameter transformation reduces the removal force needed while maintaining structural integrity during normal use, effectively resolving the contradiction between structural stability and ease of operation.
