External Communication Unit Layout for Work Vehicle Signal Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to efficiently address the challenge of maintaining a good communication state for a communication device installed within a vehicle hood, necessitating measures to enhance electromagnetic wave intensity due to attenuation.
Innovation Solution
The communication unit is positioned such that at least a part is exposed from the vehicle body, preferably located rearward of the driving seat and outward of the driving seat's outer end in the vehicle's right-left direction, with a stable support structure and wire harness configuration to improve communication state and workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the communication unit is positioned at the front of the vehicle body, then it is easily accessible, but it obstructs the driver's field of view during driving
Solution Approach 1:
The patent utilizes the rear portion of the vehicle body in the longitudinal dimension, moving the communication unit away from the driver's forward view path while maintaining accessibility through side or rear access routes.
2Ease of manufacture
If the wire harness is routed externally to connect control device and communication unit, then installation is simple, but the harness is exposed to external damage
Solution Approach 1:
The patent nests the wire harness within the vehicle body structure, routing it through internal spaces and channels. The communication unit's external positioning creates a natural nesting arrangement where the harness is protected inside while the communication interface remains accessible outside.
