Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slope work vehicles face inefficiencies and safety risks due to limited worker control over hydraulic pressure distribution, leading to potential vehicle instability on slopes.
Innovation Solution
A slope work vehicle configuration with a control means and flow amount adjustment valve allows manual adjustment of oil supply to traveling and winch actuators, preventing vehicle fall by sensing tilt and controlling oil distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic hydraulic pressure control is implemented, then response to slope inclination is improved, but worker control over hydraulic pressure distribution is lost
Solution Approach 1:
The system dynamically switches between automatic control mode (for normal operation) and manual override mode (for emergency or special situations). The control valve can automatically adjust hydraulic pressure distribution based on slope detection, but also allows manual intervention when needed, making the system adaptable to different operational requirements.
2Adaptability or versatility
If worker can arbitrarily adjust hydraulic pressure for both winch and traveling apparatus, then operational flexibility is improved, but risk of vehicle fall increases due to insufficient winch pressure
Solution Approach 1:
The system incorporates slope detection feedback that automatically adjusts hydraulic pressure distribution. When the slope exceeds a predetermined threshold, the control valve automatically increases pressure to the winch actuator to ensure adequate holding force, preventing vehicle fall while maintaining operational flexibility within safe parameters.
Solution Approach 2:
The system takes preliminary action by detecting slope conditions in advance and automatically adjusting hydraulic pressure before the vehicle becomes unstable. The control valve proactively increases winch pressure when slope detection indicates potential instability, preventing the harmful effect of vehicle fall before it occurs.
3Stability of the object's composition
If hydraulic pressure is automatically adjusted for slope response, then vehicle stability is improved, but work efficiency decreases due to limited worker control
Solution Approach 1:
The system dynamically adapts control mode based on operational needs. During normal stable conditions, automatic control maintains vehicle stability. When workers need to perform tasks requiring specific hydraulic pressure adjustments, they can manually override the automatic control, ensuring both stability and productivity are maintained according to situational requirements.
