Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a cooling unit with pump is connected to the X-ray source, then the X-ray source is cooled effectively, but energy consumption and noise level increase significantly

Engineering Contradiction:
ImproveX-ray source temperatureVSAvoidenergy consumption
Core Design Contradiction:
TemperatureVSUse of energy by moving object

Solution Approach 1:

The cooling unit operates periodically rather than continuously. The controller activates the cooling unit based on operational status: during X-ray generation operations when cooling is needed, and deactivates it during idle periods. This periodic operation significantly reduces energy consumption while maintaining effective cooling when required.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses the operational status signals from the X-ray source to automatically control the cooling unit without external intervention. The controller monitors when the X-ray source is operating and autonomously activates/deactivates the cooling unit, making the system self-regulating and reducing unnecessary energy consumption.

Inventive Principle:
Principle #25Self-service

2Temperature

Core Design Contradiction:

Solution Approach 1:

The cooling unit operates periodically rather than continuously. The controller activates the cooling unit based on operational status: during X-ray generation operations when cooling is needed, and deactivates it during idle periods. This periodic operation significantly reduces energy consumption while maintaining effective cooling when required.

The controller monitors when the X-ray source is operating and autonomously activates/deactivates the cooling unit, making the system self-regulating and reducing unnecessary energy consumption.

Inventive Principle:
Principle #25Self-service

3Temperature

If a cooling unit is provided for each X-ray source in bi-plane systems, then each source is cooled adequately, but costs and complexity increase significantly

Engineering Contradiction:
ImproveX-ray source temperatureVSAvoidcooling system complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

Multiple X-ray sources share a common cooling unit instead of each source having its own dedicated cooling unit. The controller receives operational status from multiple X-ray sources and controls the shared cooling unit accordingly, reducing system complexity and costs while maintaining adequate cooling for each source when needed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cooling unit is designed to serve multiple X-ray sources universally. The controller can manage the cooling unit based on the operational status of any connected X-ray source, making the cooling system multi-functional and adaptable to different operational scenarios without requiring separate dedicated systems.

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