Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the detector is arranged in landscape orientation, then the measurement range in the in-plane direction (β direction) is widened, but the measurement range in the out-plane direction (2θ direction) is limited

Engineering Contradiction:

Improvemeasurement rangeVSAvoiddetection direction coverage

Core Design Contradiction:

Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The detector stand incorporates a rotation mechanism that enables the detector to dynamically switch between landscape and portrait orientations. This dynamic adjustment capability allows the system to adapt to different measurement requirements, resolving the contradiction by making the detection configuration changeable rather than fixed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The stand structure is segmented into independent components including a base, a rotatable support arm, and a detector mounting mechanism. This segmentation allows the detector to be positioned at different orientations while maintaining stable support, enabling both landscape and portrait configurations without compromising structural integrity.

Inventive Principle:

Principle #1Segmentation

2Area of stationary object

If the detector is arranged in portrait orientation, then the measurement range in the out-plane direction (2θ direction) is widened, but the measurement range in the in-plane direction (β direction) is limited

Engineering Contradiction:

Improvemeasurement rangeVSAvoiddetection direction coverage

Core Design Contradiction:

Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The rotation mechanism allows the detector to switch between portrait and landscape orientations based on measurement needs. This dynamic reconfigurability ensures that the system can maximize the measurement range in either the 2θ direction or β direction as required, resolving the limitation of fixed orientation configurations.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the detector arrangement is changed by dismounting and remounting on the goniometer, then the orientation can be switched, but the process becomes time-consuming and complex

Engineering Contradiction:

Improveorientation switching capabilityVSAvoidarrangement change time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The detector stand is designed as a universal mounting system that can accommodate both landscape and portrait orientations through its rotation mechanism. This multi-functional design eliminates the need for separate mounting procedures for different orientations, allowing quick switching without time-consuming dismounting and remounting operations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The detector is pre-mounted on the rotatable stand mechanism, which is itself pre-configured to support both orientations. This preliminary setup eliminates the need for repeated attachment and detachment operations, as the rotation mechanism is already in place to handle orientation changes efficiently.

Inventive Principle:

Principle #10Preliminary action

4Device complexity

If a fixed orientation stand is used, then the structure is simple, but the measurement flexibility is reduced

Engineering Contradiction:

Improvestand structureVSAvoidmeasurement flexibility

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The stand incorporates a rotation mechanism that adds minimal structural complexity while providing significant functional flexibility. The dynamic capability to switch between orientations is achieved through a relatively simple rotational joint and positioning mechanism, resolving the contradiction between structural simplicity and measurement flexibility.

Inventive Principle:

Principle #15Dynamics

AI summary

A detector stand for an X-ray detector is provided. A first arrangement portion arranges the X-ray detector in first orientation. A second arrangement portion arranges the X-ray detector in second orientation. The X-ray detector can be fixed to a mounting portion. In the detector stand, the X-ray detector is selectively mountable on the first arrangement portion or the second arrangement portion through the mounting portion. An arrangement angle of the X-ray detector fixed to the mounting portion is different between the first orientation and the second orientation.
