Work Vehicle Position Detection Device Support Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working vehicles face difficulties in easily changing the position of position detection devices due to their placement at the center of the cabin, making it hard for workers to reach and adjust without using stepladders.
Innovation Solution
A working vehicle design that includes a support frame extending over the cabin's left and right pillars, coupled via rotatable coupling portions, allowing for easy adjustment of the position detection device without requiring workers to access the center of the cabin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the antenna unit is located at the center of the cabin in the left-right direction, then the antenna unit can be properly positioned for signal reception, but it becomes difficult for the worker to reach and adjust the antenna unit without using a stepladder
Solution Approach 1:
The patent moves the antenna unit from the traditional center position (horizontal dimension) to the front end position of the vehicle body (longitudinal dimension). This dimensional change allows the worker to access and adjust the antenna unit from the front of the vehicle, eliminating the need for stepladders while maintaining proper signal reception capability.
2Reliability
If the antenna unit is rotatably attached between a normal use position protruding upward from the roof and a non-use position lower than the roof, then the antenna unit can be protected when not in use, but it requires manual rotation and fixing by a worker at a difficult-to-reach position
Solution Approach 1:
The patent repositions the antenna unit to the front end of the vehicle body, changing its spatial location from the roof area to the front section. This dimensional relocation allows the worker to easily access and rotate the antenna unit between use and non-use positions without needing to reach difficult-to-access areas, while still providing protection when lowered.
3Ease of operation
If the support frame extends over the left and right pillars of the cabin, then the position detection device can be easily accessed from the side of the tractor, but the support frame structure becomes more complex
Solution Approach 1:
The patent extracts the antenna unit from the cabin area and relocates it to the front end of the vehicle body. This separation eliminates the need for the support frame to extend over the left and right pillars, simplifying the support frame structure while maintaining ease of access for position adjustment.
