Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator manually determines the order of applying prescribed conditions, then flexibility in treatment planning is maintained, but the operator's burden and workload increase significantly
Solution Approach 1:
The control device automatically determines the setting order by evaluating movement paths and calculating evaluation values without requiring manual intervention from the operator. The system serves itself by autonomously optimizing the treatment sequence based on predefined criteria.
Solution Approach 2:
The system changes the parameter of 'setting order' from a manually determined sequence to an automatically optimized sequence based on evaluation values. This parameter transformation enables automated control while maintaining treatment effectiveness.
2Productivity
If multiple prescribed conditions are applied sequentially without a defined order, then treatment flexibility is preserved, but treatment time and efficiency decrease
Solution Approach 1:
The control device performs preliminary evaluation of all possible setting orders before actual treatment begins. By pre-calculating evaluation values for different sequences, the system identifies the optimal order in advance, eliminating time-consuming manual determination during treatment.
Solution Approach 2:
The system uses evaluation values as feedback to determine the optimal setting order. By continuously monitoring and comparing evaluation metrics, the control device selects the sequence that minimizes treatment time and maximizes efficiency.
3Ease of operation
If the operator manually sets the setting order, then adaptability to special treatment requirements is maintained, but physical and mental stress on the operator increases
Solution Approach 1:
The control device autonomously handles the complex task of determining setting orders, freeing the operator from manual calculation and decision-making. This self-service approach reduces physical and mental stress while maintaining treatment adaptability through programmed evaluation criteria.
4Extent of automation
If automated determination of setting order is implemented, then operator burden is reduced, but complexity of the control system increases
Solution Approach 1:
The control device integrates multiple functions including movement path determination, evaluation value calculation, and setting order optimization into a single unified system. This multi-functionality approach automates setting order determination while managing system complexity through consolidation rather than proliferation of separate components.

AI summary
A particle beam therapy apparatus that reduces a burden on an operator is provided. The invention is directed to a particle beam therapy apparatus. The position and posture setter 32 moves a movable body, that is at least one of the irradiation nozzle 16 and the treatment table 18 that is capable of motion, and sets a relative position and posture of the irradiation nozzle 16 and the treatment table 18 . The movement path determiner 44 determines a movement path of the movable body when adapting the positional posture of the movable body from one condition among a plurality of prescribed conditions to another condition. The evaluation value determiner 46 obtains an evaluation value for a case of adapting the positional posture of the movable to each of a plurality of pre scribed conditions. This evaluation value is an evaluation value for a case of moving the movable body according to the movement path. The order determiner 48 determines a setting order for adapting the positional posture of the movable body to each prescribed condition based on the evaluation value. The position and posture setter 32 adapts the positional posture of the movable body to each of the plurality of prescribed conditions by moving the movable body according to the movement path determined by the movement path determiner 44.
