Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate controllers are used for heat insulated jacket and fan jacket, then each appliance can have dedicated voltage control, but device complexity increases and convenience decreases
Solution Approach 1:
The voltage control device is designed to universally control both heat insulated jackets and fan jackets through a single controller. The controller includes an appliance connector that can identify different appliance types and automatically adjust control parameters, enabling one controller to perform multiple functions that previously required separate dedicated controllers
Solution Approach 2:
The patent combines the control functions for heat insulated jackets and fan jackets into a single integrated controller. The controller integrates voltage output circuits, control circuits, and appliance identification functionality into one unified device, eliminating the need for separate controllers and reducing overall system complexity
2Device complexity
If a single voltage control device is used for multiple appliance types, then convenience improves and device quantity reduces, but the controller must handle diverse voltage requirements
Solution Approach 1:
The controller employs dynamic control strategies where control parameters are not fixed but adapt based on the connected appliance type. The control circuit dynamically adjusts voltage output levels, switching between fixed voltage mode for heat insulated jackets and variable voltage mode for fan jackets, allowing the single controller to handle diverse voltage requirements effectively
Solution Approach 2:
The patent implements parameter changes by detecting appliance type and automatically adjusting control parameters. When a heat insulated jacket is detected, the controller sets fixed voltage parameters; when a fan jacket is detected, it enables variable voltage parameters. This automatic parameter adaptation allows one controller to serve multiple appliance types with different electrical characteristics
