Vehicle Winch Control System with Delay Shutoff for Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle winches often pose safety risks due to inability to accurately and timely shut off, leading to potential safety hazards and reduced user experience, especially in rescue scenarios where manual shutoff is complicated and automatic shutoff can cause frequent startups.
Innovation Solution
An apparatus and method for controlling a vehicle winch, incorporating an instant control component for starting and controlling the rotation direction, and a delay control component that acquires running parameters to safely shut off the winch, utilizing detectors and a timer to ensure timely and accurate power-off based on preset thresholds for power-off duration, current, and temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual shutoff control is used, then the winch can be controlled to start and stop, but the user experience is poor and safety risks increase due to inability to timely shut off
Solution Approach 1:
The winch control system performs self-service by automatically monitoring its own running parameters (current, temperature, operation duration) and making shutdown decisions based on preset thresholds, eliminating the need for manual intervention and ensuring timely shutdown for safety
Solution Approach 2:
The system implements feedback control by continuously monitoring running parameters through detectors and comparing them against preset thresholds, automatically adjusting the winch operation state based on the monitored parameters to improve both ease of operation and safety
2Reliability
If automatic shutoff is implemented, then safety is improved through timely shutdown, but frequent startups occur during rescue operations
Solution Approach 1:
The system uses parameter changes (preset thresholds for current, temperature, and operation duration) to control shutdown timing, adjusting these parameters to balance safety requirements with operational continuity to prevent frequent shutdowns during rescue operations
Solution Approach 2:
The control system dynamically adjusts shutdown decisions based on real-time monitoring of multiple running parameters, allowing flexible adaptation to different operational conditions while maintaining safety standards and preventing unnecessary shutdowns
3Measurement precision
If continuous monitoring of running parameters is implemented, then accurate shutdown timing is achieved, but device complexity increases
Solution Approach 1:
The control unit performs multiple functions including parameter monitoring, threshold comparison, shutdown decision-making, and control signal generation, consolidating these functions into a single component to achieve accurate shutdown timing without significantly increasing overall system complexity
Solution Approach 2:
The control unit acts as an intermediary between the detectors and the winch motor, processing monitoring data and translating it into appropriate control actions, simplifying the overall control architecture while maintaining precise shutdown timing
