Working Vehicle Position Detector Bracket for Steering Lockout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic steering control in working vehicles is compromised when the position detector is moved to a second position lower than its operational position, leading to inaccurate navigation and potential collisions with obstacles.
Innovation Solution
A support bracket with a pivotal shaft and mounting stay is used to move the position detector between its operational and lower positions, with the mounting stay acting as a restraint by covering the detector when in the second position, preventing satellite signal reception and thus inhibiting automatic steering control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the position detector is moved to the second position (lower position) for storage or protection, then the device is protected from damage or obstruction, but automatic steering control cannot be performed with high accuracy
Solution Approach 1:
The position detector is mounted on a support bracket that can be dynamically adjusted between a first position (for use) and a second position (lower than the first position). The support bracket includes a pivotal shaft and a mounting stay that can rotate around the pivotal shaft, allowing the position detector to be moved between positions. This dynamic positioning system enables the operator to switch between operational and protective modes as needed.
2Reliability
If the position detector is kept in the second position to protect it, then the device is safe from damage, but automatic steering control cannot be performed
Solution Approach 1:
The mounting stay includes a plate that reflects satellite signals. When the position detector is in the second position, the mounting stay is positioned above the position detector and covers over it, restraining automatic steering control by preventing satellite signal reception. This preliminary blocking mechanism ensures that even if the system mistakenly detects the detector as being in the first position, automatic steering control cannot be performed when the detector is actually in the second position.
3Reliability
If the position detector is moved between positions using a support bracket, then the detector can be protected when not in use, but the device complexity increases
Solution Approach 1:
The mounting stay serves multiple functions: it supports the position detector, provides a reflective plate for satellite signals, and acts as a cover to restrain automatic steering control when the detector is in the second position. The support bracket structure with pivotal shaft and mounting stay is designed to be compact and integrated with the vehicle body, minimizing space requirements while providing protection and control functionality.

Function Achieved in This Case
Prevents automatic steering control from being performed when the position detector is in the second position, ensuring accurate navigation and preventing potential collisions by physically obstructing the satellite signal, thereby maintaining operational safety.
Implementation Method 1
the mounting stay includes a plate that reflects the signal transmitted from the positioning satellite

AI summary
A position detector is supported to be movable between a first position and a second position lower than the first position. A mounting stay is below the position detector when the position detector is in the first position, and, when the position detector is rotated together with the mounting stay from a state in which the position detector is in the first position, the position detector is moved to the second position and the mounting stay is positioned above the position detector in the second position and covers over the position detector so as to restrain the automatic steering control.
