Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotational gantry is used to deliver radiation beams from multiple directions, then the radiation treatment capability is improved, but the device becomes bulky, costly, and less practical
Solution Approach 1:
Instead of rotating the radiation beam emitter (gantry) to change irradiation directions, the patent inverts the approach by rotating the subject on a movable supporting device. This allows the same fixed emitter to treat the target region from multiple directions by changing the subject's orientation, thereby achieving multi-directional treatment without a bulky rotational gantry.
Solution Approach 2:
The patent replaces the complex mechanical rotational gantry system with a simpler movable supporting device that rotates the subject. This substitution reduces device complexity while maintaining the capability to deliver radiation from multiple directions, addressing the contradiction between treatment versatility and device simplicity.
2Adaptability or versatility
If a rotational gantry is used to deliver radiation beams from multiple directions, then multi-directional irradiation is achieved, but the cost and practicability decrease
Solution Approach 1:
The patent inverts the conventional approach by keeping the radiation emitter fixed and rotating the subject instead. This inversion eliminates the need for an expensive rotational gantry while achieving the same multi-directional irradiation capability, thereby improving ease of manufacture and practicability.
Solution Approach 2:
The movable supporting device is designed as a simpler, more cost-effective alternative to a rotational gantry. By using a less complex mechanical structure that rotates the subject rather than the emitter, the system achieves multi-directional treatment at lower cost, aligning with the principle of using simpler components when possible.
3Device complexity
If the radiation beam emitter is fixed in position, then the device structure is simplified, but the ability to irradiate from different directions is limited
Solution Approach 1:
The patent resolves this contradiction by inverting which component moves: instead of moving the emitter to change directions, the subject is rotated on the movable supporting device. This allows a fixed emitter to achieve multi-directional irradiation capability, simultaneously simplifying device structure and maintaining adaptability.
Solution Approach 2:
The patent introduces dynamics to the subject positioning system through the movable supporting device that can rotate the subject to different orientations. This dynamic adjustment of the subject's position and orientation enables a fixed emitter to deliver radiation from multiple directions, achieving versatility without increasing emitter complexity.
