Communication Module Rigid Grip for High-Density Slot Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication modules face difficulties in being easily inserted and removed from adjacent slots due to obstacles from already inserted modules, leading to potential damage of connection points and flexibility issues with pull tabs, especially in densely arranged slot configurations.
Innovation Solution
A communication module design featuring a casing with a latch arm and a rigid grip portion, which is either metal or synthetic resin, allowing for easy insertion and removal by sliding the latch arm and providing sufficient rigidity to prevent bending, with a grip portion that is narrower than the casing and communication cable, ensuring easy access and preventing interference with adjacent modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the communication module is inserted by pinching the casing, then the insertion operation is simple, but it becomes difficult or impossible to insert when adjacent slots are occupied
Solution Approach 1:
A grip portion is introduced as an intermediary component between the operator's hand and the communication module. This grip portion extends from the rear surface of the casing and provides a dedicated handling area that allows insertion without pinching the casing itself, thereby enabling easy insertion even when adjacent slots are occupied.
2Adaptability or versatility
If the communication cable is held to insert the module, then insertion is possible in occupied slots, but the connection portion between cable and board may be damaged
Solution Approach 1:
The grip portion serves as a mediator that transfers the insertion force from the operator's hand to the casing, bypassing the need to hold the communication cable. This ensures that the connection portion between the cable and board is not subjected to damaging forces during insertion operations.
3Ease of operation
If a flexible pull tab is used, then the pull tab can be easily manipulated, but it may be bent or twisted by surrounding communication cables in high-density arrangements
Solution Approach 1:
The grip portion is designed with a curved surface that is comfortable to grip and manipulate. This curved geometry provides ergonomic advantages while maintaining structural rigidity, allowing easy operation without being bent or twisted by surrounding cables in high-density slot arrangements.
4Productivity
If slots are arranged densely to increase capacity, then the panel utilization is improved, but the difficulty of insertion and removal increases due to obstacles from adjacent modules
Solution Approach 1:
The communication module is segmented into distinct functional parts: the casing containing the communication device, the communication cable extending from the casing, and the grip portion extending from the rear surface of the casing. This segmentation allows the grip portion to provide a clear access path for insertion and removal operations, even when slots are densely arranged.
Solution Approach 2:
The grip portion acts as an intermediary element that facilitates interaction between the operator and the communication module in high-density configurations. By providing a dedicated handling interface that extends from the rear surface, it enables easy grasping and manipulation without interference from adjacent modules.

AI summary
A communication module inserted into and removed from a slot provided in a communication device, the communication module includes a communication cable, a casing disposed at an end of the communication cable and capable of being inserted into and removed from the slot, a latch arm slidable along the casing, and a grip portion extending from the casing. When the latch arm is operated so as to slide, an engagement between the casing and the slot is released, and the grip portion is connected to the latch arm such that the latch arm can be operated so as to slide, and the grip portion also has rigidity so as not to be bent by a weight of the casing.
