Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Signal output ports located at the rear side of rack-mounted devices are difficult to access, necessitating an apparatus to enhance accessibility.
Innovation Solution
A signal access extender apparatus comprising a rackmount enclosure, a lid, a printed circuit board, and a circuit function board that fits into a compartment of a rack system, electronically coupling to a harness and a printed circuit board, providing access to signal ports through custom connectors and adapters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If signal output ports are located at the rear side of rack-mounted devices, then device integration is improved, but port accessibility deteriorates
Solution Approach 1:
The patent introduces an intermediary device (signal access extender or adapter) that couples between the rear-side harness connector and the front panel. This intermediary component receives signals from the rear harness and provides accessible front-panel ports, effectively mediating between the rear-mounted harness and front-access requirements without modifying the original device architecture.
2Volume of moving object
If signal output ports are located at the rear side, then device compactness is improved, but maintenance time increases
Solution Approach 1:
The adapter serves as a maintenance intermediary by providing front-accessible test points and signal ports that allow technicians to perform diagnostics and troubleshooting without rear-panel access. This enables maintenance personnel to work from the front of the rack, significantly reducing maintenance time while preserving the compact rear-mounted harness configuration.
3Device complexity
If signal output ports are located at the rear side, then device structure is simplified, but fault resolution difficulty increases
Solution Approach 1:
The adapter acts as a diagnostic intermediary by providing accessible test points, measurement ports, and signal access points on the front panel. This allows fault detection and measurement instruments to connect at the front rather than requiring rear access, making fault resolution as easy as the original device structure while maintaining structural simplicity.

AI summary
A signal access extender apparatus includes a rackmount enclosure, a rackmount enclosure lid coupled to the rackmount enclosure, the rackmount enclosure and the rackmount enclosure lid defining a shape of the signal access extender apparatus, a printed circuit board inserted into a front end of the rackmount enclosure, a circuit function board included in the rackmount enclosure and coupled at one end of the circuit function board to a harness and at another end to the printed circuit board. The signal access extender apparatus is insertable into a compartment of a rack system to replace a unit in the compartment, the shape of the signal access extender apparatus being substantially the same as the unit being replaced and being such that the signal access extender apparatus fits within and substantially fills the compartment, the signal access extender apparatus electronically coupling to the harness and to the printed circuit board.
