Solution Overview

Problem

The existing charged particle acceleration devices require repeated precise alignment adjustments during transitions between adjustment and normal operation states, leading to significant time consumption.

Innovation Solution

The charged particle acceleration device incorporates a reversible stage system with a linear-motion driver and height-adjustable coupling members, allowing controllers to be accurately positioned and returned to their original trajectory without the need for realignment, by using a moving plate and fixing plate assembly that can be evacuated and reintegrated along the beam trajectory.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If control devices are installed and removed repeatedly between adjustment and normal states, then the accelerator can perform both adjustment and operation functions, but alignment adjustment must be repeated each time consuming significant time

Engineering Contradiction:

Improveability to switch between adjustment and normal statesVSAvoidtime spent on repeated alignment adjustment

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The control devices are pre-aligned with the beam trajectory when installed on the stage. This preliminary alignment action is performed only once during initial installation, and the pre-aligned stage is then moved to different positions (adjustment position or normal operation position) without requiring repeated alignment adjustments, thus resolving the time loss contradiction

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The stage supporting the control devices is made movable rather than fixed, allowing it to be dynamically repositioned between adjustment position and normal operation position. This dynamic positioning capability enables the system to switch between states without requiring repeated alignment, as the stage maintains its pre-established alignment relationship with the beam trajectory during movement

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If control devices are fixed in position for normal operation, then alignment accuracy is maintained, but the devices cannot be easily removed or repositioned for adjustment

Engineering Contradiction:

Improvealignment accuracy of control devicesVSAvoidease of removing and repositioning control devices

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The system is segmented into a movable stage carrying the control devices and a fixed beam trajectory structure. This segmentation allows the control devices to be easily removed by simply moving the entire stage away from the beam trajectory, while maintaining alignment accuracy when the stage is positioned correctly. The segmentation enables both easy removal/repositioning and precise alignment to coexist

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The stage acts as an intermediary carrier between the control devices and the beam trajectory. It provides a standardized interface that facilitates easy installation and removal, while incorporating alignment features that ensure precise positioning when installed. This intermediary structure resolves the contradiction by decoupling the ease of removal from the precision of positioning

Inventive Principle:

Principle #24Intermediary (Mediator)
