Solution Overview
Problem
Industrial trucks often travel at excessive speeds over uneven routes, leading to vehicle wear, health risks for drivers, and potential damage to loaded items due to inadequate consideration of potholes and obstacles.
Innovation Solution
An industrial truck control system that uses sensors to record and store data on route irregularities, allowing for adaptive control of speed, lifting height, and steering to mitigate these risks, with options for on-board or central system configurations and communication links for data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If industrial trucks travel at high speed to improve productivity, then productivity increases, but vehicle wear and driver health risks increase due to uneven routes
Solution Approach 1:
The system performs preliminary detection of route irregularities using sensors (cameras, scanners, piezoelectric sensors) before the truck encounters them. Data about potholes, bumps, and obstacles are recorded and stored in advance, allowing the control system to prepare appropriate speed adjustments before the truck reaches problematic areas, thus preventing damage while maintaining overall productivity
Solution Approach 2:
The control system continuously receives feedback from sensors about the truck's position and detected irregularities. Based on this feedback, the system automatically adjusts speed and lifting height in real-time. The system also provides feedback to the driver through displays or warnings, enabling informed decision-making to balance productivity with vehicle and driver safety
2Duration of action of stationary object
If drivers manually navigate routes to avoid irregularities, then vehicle wear reduces, but driving time increases due to cautious operation
Solution Approach 1:
The control system performs self-service by automatically detecting route irregularities and adjusting driving parameters without requiring continuous manual intervention from the driver. The system autonomously processes sensor data, determines appropriate speed adjustments, and executes control actions, thereby extending vehicle service life while minimizing additional driving time through automated rather than manually cautious operation
Solution Approach 2:
The system replaces manual driver judgment and mechanical reaction with automated sensor-based detection and electronic control. Optical sensors, piezoelectric sensors, and microprocessors substitute for human perception and response, enabling faster and more consistent adjustments that protect the vehicle without the time loss associated with cautious manual driving
3Strength
If speed is reduced over uneven ground to prevent damage, then item damage reduces, but productivity decreases due to slower operation
Solution Approach 1:
The control system applies local quality by adjusting speed and lifting height specifically at locations where irregularities are detected, rather than reducing speed uniformly along the entire route. The system identifies precise positions of potholes, bumps, and obstacles using position sensors and targetedly modifies driving parameters only in those local areas, thereby protecting items from damage while maintaining high speed during normal sections
Solution Approach 2:
The system dynamically adjusts driving parameters based on real-time conditions. Speed and lifting height are not fixed but vary continuously according to the detected route profile. The control system modulates these parameters up and down as the truck approaches and passes irregularities, enabling item protection during critical moments while maximizing productivity during safe sections
