Operator Seat Mounting for Stable GNSS Correction Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Working machines experience unstable communication and inaccurate position correction due to the presence of low radio wave transparency materials and improper mounting of correction information communicator assemblies, leading to potential communication failures and errors.
Innovation Solution
The correction information communicator assembly is positioned in the vicinity of the operator's seat, preferably inside a mount with a radio wave-transparent cover, ensuring stable wireless communication and accurate position correction by minimizing interference and exposure to external factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the correction information communicator assembly is mounted in locations with many low radio wave transparency members (such as steel plates), then the device can be installed in structurally sound areas, but the communication stability deteriorates and position correction accuracy decreases
Solution Approach 1:
The correction information communicator assembly is extracted from the general vehicle body structure and specifically positioned in the operator's seat vicinity, where radio wave transparency is higher. This separates the communication function from areas with harmful steel plate interference.
Solution Approach 2:
The patent identifies specific local areas around the operator's seat that have different radio wave transparency characteristics compared to other vehicle body parts. The assembly is positioned in this favorable local zone to optimize communication while maintaining structural integrity.
2Ease of operation
If the correction information communicator assembly is mounted without determining the optimal location, then the device can be installed quickly and easily, but the assembly may contact surrounding structures due to vibrations or the communication harness may receive excessive load
Solution Approach 1:
The operator's seat vicinity is identified as an equipotential zone that balances multiple requirements: sufficient space for assembly installation, adequate radio wave transparency, and distance from high-vibration contact points. This location provides a stable mounting environment without compromising communication reliability.
3Ease of operation
If the correction information communicator assembly is positioned in areas with high vibration and potential contact with surrounding structures, then the device can be mounted in accessible locations, but the communication harness may receive excessive load resulting in communication failure
Solution Approach 1:
The operator's seat structure serves as an intermediary mounting platform that provides mechanical support while isolating the correction information communicator assembly from direct contact with high-vibration components. This intermediate position reduces stress transmission to the communication harness.
