Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional dip switches are used to control multiple heat carriers with different wattages or heating zones, then the heating module can provide different heating functions, but the cost increases and application flexibility is limited

Engineering Contradiction:
Improveheating function flexibilityVSAvoidcontrol device complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal control system where a single programmable controller can manage multiple heating carriers with different wattages and zones by loading different control algorithms. This replaces the need for multiple dedicated control devices (dip switches), achieving multi-functionality while reducing overall system complexity and cost.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system changes control parameters (binary values representing reference voltage and feedback proportion) to adapt the heating module's behavior for different heating carriers. By modifying these parameters through software rather than hardware reconfiguration, the system achieves versatility without increasing physical complexity.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple heat carriers with different wattages are used to provide various heating functions, then the application range expands, but the control device cost increases

Engineering Contradiction:
Improveapplication rangeVSAvoidcontrol device cost
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses binary value copies (digital representations) to control different heating carriers instead of requiring separate physical control devices for each carrier. The programmable controller stores and retrieves control algorithms as data copies, enabling multiple heating configurations without proportional increases in hardware cost.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces mechanical/dip-switch-based control systems with an electronic programmable control system. This substitution eliminates the need for multiple physical control devices while expanding application range, as software can be reconfigured to control different heating scenarios without additional hardware.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
