Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If orientation sensors are installed in both radiation generation device and radiation detection device to determine whether radiography can be performed, then the determination accuracy is improved, but the device complexity and size increase

Engineering Contradiction:

Improvedetermination accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts the orientation detection function from both devices and consolidates it into a single orientation detection sensor. Instead of having separate sensors in the radiation generation device and radiation detection device, the system uses one orientation detection sensor to detect the orientation of either device, thereby reducing overall system complexity while maintaining determination accuracy.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The orientation detection sensor serves multiple functions: it can detect the orientation of the radiation generation device, the radiation detection device, or either one of them. This multi-functionality allows the system to determine whether radiography can be performed without requiring separate dedicated sensors for each device, thus reducing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

Solution Approach 1:

The patent extracts the orientation detection function from both devices and consolidates it into a single orientation detection sensor. Instead of having separate sensors in the radiation generation device and radiation detection device, the system uses one orientation detection sensor to detect the orientation of either device, thereby reducing overall system complexity while maintaining determination accuracy.

Inventive Principle:

3Device complexity

If a simple configuration is used without orientation sensors in both devices, then the device complexity is reduced, but the ability to determine whether radiography can be performed is compromised

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent introduces an orientation detection sensor as an intermediary component that provides orientation information to the control unit. This intermediary approach allows the system to maintain simple device configurations while still achieving reliable determination of whether radiography can be performed, as the control unit uses the orientation information from the sensor to make the determination.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback through the orientation detection sensor that continuously provides orientation information to the control unit. The control unit uses this feedback to determine whether radiography can be performed, ensuring reliable operation while maintaining a simple device configuration.

Inventive Principle:

Principle #23Feedback
