Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing racks with modular designs, determining whether the mating gap between modules meets design requirements is difficult through external observation alone, as actual connection positions between modules are hidden within the chassis.
Innovation Solution
A communication device board with a connector featuring a fixed position and a contact position of different levels, utilizing a conductive resilient sheet with an insulating coating, where the sheet's level changes indicate proper connection or disconnection, allowing a logic chip to generate level transition signals for determining insertion or removal status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If modules are connected using traditional connectors with hidden connection positions, then the rack structure is compact and modular, but it becomes difficult to determine whether the mating gap between modules meets design requirements
Solution Approach 1:
The patent introduces a visual dimension to the connector by creating a visible indicator structure that extends beyond the traditional hidden connector interface. The indicator includes a first part visible from the front and a second part visible from the side, transforming the three-dimensional hidden connection state into multiple two-dimensional observable planes, thereby enabling external observation of mating gap status without complicating the internal connector structure.
Solution Approach 2:
The patent introduces a visible indicator as an intermediary element between the hidden connector and the external observer. This indicator serves as a mediator that translates the internal mating gap state into external visual signals, allowing determination of connection status without directly exposing the complex internal connector structure or requiring direct measurement of the mating gap.
2Ease of manufacture
If the connector structure is simplified for easier assembly, then the ease of manufacture improves, but the ability to detect connection status externally deteriorates
Solution Approach 1:
The patent segments the indicator into distinct functional parts: a first part visible from the front and a second part visible from the side. This segmentation allows each part to serve its specific observational purpose while keeping the overall indicator structure simple and easy to manufacture. The segmented design enables external detection of connection status without requiring complex integrated structures.
Solution Approach 2:
The patent utilizes visual differentiation (analogous to color changes) by creating indicator parts with different visibility characteristics from different directions. The first and second parts are designed to be visible from different angles, creating visual cues that indicate connection status. This visual coding approach simplifies detection without requiring complex electronic or mechanical sensing mechanisms.

AI summary
Communication device board and a communication device are provided. A connector of the communication device board includes a fixed position and a contact position. The fixed position and the contact position; have different levels. The fixed position is fixedly connected one end of an inner side of a conductive resilient sheet. An outer side of the conductive sheet is provided with an insulating coating. When the fixed position fixedly connected to the end of the inner side of the conductive resilient sheet, and a mating gap between the connector of the communication device board and a corresponding communication device connector is smaller than a preset threshold range, A second end of the inner side of the conductive resilient sheet is in contact with the contact position (12).
