Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If multiple trial iterations are performed to adjust beam size and position, then beam adjustment accuracy is improved, but duct activation and damage increase

Engineering Contradiction:

Solution Approach 1:

The patent applies preliminary action by using simulation technology to pre-calculate and determine optimal beam adjustment parameters before actual physical adjustment. The simulation system models the particle beam transport route and predicts the effects of parameter changes, allowing the actual adjustment process to skip multiple trial iterations and directly achieve accurate beam size and position settings without causing duct activation or damage through repeated physical trials.

2Manufacturing precision

If multiple trial iterations are performed to adjust beam size and position, then beam adjustment accuracy is improved, but manufacturing time increases

Engineering Contradiction:

Solution Approach 1:

The patent applies copying by creating a virtual simulation model of the particle beam transport route that replicates the physical system's behavior. This digital copy allows repeated experimentation and parameter optimization without consuming physical time or resources. The simulation model processes beam adjustment calculations much faster than physical trials, enabling accurate beam size and position determination through computational rather than temporal iteration, thus significantly reducing manufacturing time.

Solution Approach 1:

The patent applies self-service by implementing an automated simulation system that performs beam adjustment calculations and optimization autonomously. The simulation environment automatically tests different parameter combinations, evaluates beam performance metrics, and determines optimal adjustment values without requiring manual intervention or iterative physical experimentation. This automation significantly reduces the work burden by replacing manual trial-and-error operations with automated computational processes that achieve the same accuracy more efficiently.

Inventive Principle:
Principle #25Self-service
