Dual-Mode Work Vehicle Operation When Remote Control Fails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicles face difficulty in movement when the remote operation device fails or loses power, necessitating a separate device for manual operation, complicating the process.
Innovation Solution
A work vehicle equipped with both a remote operation device and an in-vehicle operation device, allowing for two operation modes: one using the remote device and another using the in-vehicle device, ensuring mobility in both scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the traveling machine body is operated using only the remote operation device, then ease of operation is improved, but reliability deteriorates because the machine body cannot be moved when the remote operation device fails
Solution Approach 1:
The work vehicle is designed with dual operation capabilities: it can be operated both remotely via the remote operation device and locally via the in-vehicle operation device. This multi-functionality ensures that the traveling machine body can be moved under any circumstance, whether the remote device is functioning or not, thereby resolving the contradiction between ease of operation and reliability
2Reliability
If a separate device is prepared to move the traveling machine body when the remote operation device fails, then reliability is improved, but device complexity increases
Solution Approach 1:
Instead of preparing a completely separate device for moving the traveling machine body, the invention merges the operation functionality into the work vehicle itself by equipping it with both remote operation capability and in-vehicle operation capability. This integration reduces device complexity while maintaining reliability

AI summary
[Problem] To provide a technique capable of easily moving a traveling machine body in both a state where the traveling machine body may be operated by a remote operation device and a state where the traveling machine body may not be operated by the remote operation device. [Solution] A work vehicle includes a traveling machine body, an in-vehicle operation device that is installed in the traveling machine body and that operates the traveling machine body, and a remote operation device that is provided separately from the traveling machine body and that operates the traveling machine body. The work vehicle has a first operation mode for operating the traveling machine body using the remote operation device and a second operation mode for operating the traveling machine body using the in-vehicle operation device.
