Dual-Earcup Headset Data Routing With Fewer Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased interconnectivity of devices in combat or rescue scenarios necessitates a reduction in the number of cables required for headsets to facilitate data exchange between body-worn devices.
Innovation Solution
A headset configured with interconnected ear cups that include communication interfaces and interconnection cables, allowing for the exchange of non-audio data and audio signals between external devices worn by the user, such as helmet-mounted devices and those in vest pockets, through wireless and detachable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cables are connected to the headset for data exchange between external devices, then the headset can communicate with multiple external devices, but the number of cables increases and the risk of damage increases
Solution Approach 1:
The patent combines multiple cable connections into a single interconnection cable by integrating multiple communication interfaces (first communication interface in first ear cup, second communication interface in second ear cup) into one unified cable system. This merging approach maintains the capability to exchange data with multiple external devices while reducing the total number of separate cables from two or more to just one interconnection cable.
Solution Approach 2:
The interconnection cable is designed with multi-functionality to handle various types of data exchange (audio signals, non-audio data, sensor data, actuator data) between the headset and multiple external devices simultaneously. The cable serves universal communication purposes for different device types including helmet-mounted devices, vest-pocket devices, and other body-worn equipment, eliminating the need for device-specific cables.
2Adaptability or versatility
If multiple cables are connected to the headset, then data exchange with external devices is enabled, but the ease of operation decreases due to cable management difficulties
Solution Approach 1:
By merging multiple separate cable connections into a single interconnection cable that connects to both ear cups, the patent significantly improves ease of operation. The user no longer needs to manage multiple separate cables, plug and unplug multiple connectors, or deal with tangled wire bundles. The single cable system is much easier to handle, store, and maneuver in combat or rescue scenarios.
3Adaptability or versatility
If multiple separate cables are used for connecting external devices, then each device can be connected independently, but the risk of damage increases in challenging environments
Solution Approach 1:
The patent reduces the risk of cable damage by combining multiple separate cables into a single interconnection cable system. Fewer cables mean fewer potential failure points, less exposure to environmental damage, and reduced wear from handling. The unified cable structure is more reliable in challenging combat or rescue environments where cables are subject to stress, moisture, and physical damage.
