Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomously traveling work vehicles face challenges such as inability to continue traveling due to inclines or obstacles, theft prevention inefficiencies, and maintenance difficulties, particularly when operating in areas not visible to users.
Innovation Solution
Equipping work vehicles with inclination sensors, captured image acquisition units, and determination units to assess travel feasibility, along with theft prevention mechanisms like identification-based charging and contact sensors, and integrating base stations for autonomous maintenance and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the work vehicle operates autonomously in remote locations, then work coverage is improved, but theft risk increases
Solution Approach 1:
The patent implements a feedback mechanism where the work vehicle continuously transmits its location and status to the user's terminal device. This allows real-time monitoring of the vehicle's whereabouts, enabling the user to detect abnormal movements or potential theft attempts and take appropriate actions, thus resolving the contradiction between autonomous operation and theft risk
Solution Approach 2:
The patent introduces a communication system as an intermediary between the work vehicle and the user. This intermediary enables remote monitoring and control capabilities, allowing the user to track the vehicle's location and receive alerts, thereby mitigating theft risk while maintaining autonomous work coverage
2Productivity
If the work device is mounted on the bottom side of the vehicle body, then work performance is improved, but maintenance accessibility deteriorates
Solution Approach 1:
The patent divides the work device into separable components that can be independently accessed. The work device is designed with quick-release mechanisms and modular structures, allowing maintenance personnel to remove and service individual components without disassembling the entire vehicle, thus resolving the contradiction between optimal work positioning and maintenance accessibility
3Adaptability or versatility
If the work vehicle operates in locations not visible to the user, then work flexibility is improved, but monitoring capability deteriorates
Solution Approach 1:
The patent replaces direct visual mechanical monitoring with electronic sensing and communication systems. Sensors on the vehicle capture environmental data and transmit it to the user's terminal, enabling remote monitoring of work conditions, location, and status without requiring the user to be physically present, thus resolving the contradiction between work flexibility and monitoring capability
