Control method and system for vehicle-mounted refrigerator, related device and vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted refrigerators have limited control capabilities, primarily functioning for cooling only, lacking integrated control systems for additional functions such as visual display, heating, lighting, and door locking/unlocking.
Innovation Solution
A control system integrating a main control board, display panel, and motor driver to manage door operation, illumination, and temperature adjustment, enabling comprehensive control over multiple functions including door locking/unlocking, illumination brightness, and temperature regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vehicle-mounted refrigerator is designed with a single cooling function, then the device complexity is reduced and ease of manufacture is improved, but the adaptability and versatility are worsened
Solution Approach 1:
The main control board is designed to universally control multiple functions including door locking/unlocking, lighting brightness adjustment, and temperature regulation, replacing the need for separate control systems for each function. This enables the refrigerator to perform diverse operations through a single integrated control unit, thereby improving functional versatility while managing device complexity.
2Adaptability or versatility
If multiple functions are integrated into the control system, then the adaptability and versatility are improved, but the device complexity increases
Solution Approach 1:
Multiple control functions for door locking, lighting, and temperature control are merged into a single main control board, reducing the number of separate control units needed. This integration simplifies the manufacturing process by reducing the quantity of components that need to be assembled and tested, while still providing diverse functional capabilities.
3Ease of operation
If a single control system manages multiple functions, then the device complexity is reduced, but the ease of operation for individual functions may be worsened
Solution Approach 1:
The control system provides dedicated control interfaces for each specific function (door locking, lighting, temperature control) on the display panel, allowing users to easily access and operate each function independently. This localized control approach ensures that each function remains simple to operate despite being managed by an integrated control system.
