Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a C-arc structure is used to suspend X-ray source and detector, then rotational movement around object is achieved, but the structure becomes bulky and heavy
Solution Approach 1:
The C-arc structure is divided into multiple segments connected by pivot joints, allowing the support structure to be assembled from lighter individual components rather than using a single heavy continuous arc
Solution Approach 2:
The structure transitions from a static C-arc to a dynamic assembly of linked segments that can rotate and pivot, enabling the same rotational functionality with reduced structural mass
2Adaptability or versatility
If a C-arc structure is used for suspension, then rotational movement is enabled, but the structure becomes cumbersome to operate
Solution Approach 1:
By segmenting the C-arc into multiple pivot-connected sections, each segment can be independently positioned and controlled, simplifying the operation compared to maneuvering a single heavy continuous structure
Solution Approach 2:
Pivot joints serve as intermediary elements between segments, providing simple rotational connections that ease the transmission of movement and reduce the complexity of controlling the overall structure
3Adaptability or versatility
If a C-arc structure is used, then angular rotation is achieved, but rotation range is limited due to size and complexity
Solution Approach 1:
The linked segment structure with pivot joints creates a more flexible system that can achieve larger angular rotations without the size constraints of a traditional continuous C-arc
Solution Approach 2:
The pivot joints introduce additional degrees of freedom beyond simple angular rotation, allowing movement in multiple dimensions that expands the effective rotation range
4Reliability
If traditional C-arc suspension is used, then imaging devices are supported, but synchronization of components for angulation rotation requires considerable effort
Solution Approach 1:
Multiple support functions are merged into the unified pivot-linked structure, where all imaging devices are automatically synchronized through their common mechanical connection rather than requiring independent synchronization control
Data Source
AI summary
A support arrangement for generating an X-ray image is provided. The arrangement includes a support structure configured to hold an image detector at a first end and an X-ray source at a second end, with a connection line in between on which an Iso-centre is located. The support structure connects to a primary supporting beam in a first pivotable connection point; the primary supporting beam connects to a secondary supporting beam in a second pivotable connection point; and the secondary supporting beam connects to a mounting arrangement in a third pivotable connection point. A rhombus shape is defined by: (i) a connection line between the first and second pivotable connection points; (ii) a connection line between the second and third pivotable connection points; (iii) a connection line between the third pivotable connection point and the Iso-centre; and (iv) a connection line between the Iso-centre and the first pivotable connection point.
