Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If measuring instruments are installed inside the vacuum chamber to directly measure accelerating tube position, then measurement accessibility is improved, but measurement reliability deteriorates due to high temperature and harmful materials affecting the instruments

Engineering Contradiction:

Improvemeasurement accessibilityVSAvoidmeasurement reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces viewports as intermediary components that allow optical measurement signals to pass through the vacuum chamber wall without direct contact between the measurement system and the harsh vacuum environment. The micro-alignment telescope and lens devices are positioned outside the vacuum chamber, using the viewport as a transparent interface to measure the accelerating tube position indirectly, thus protecting the instruments from high temperature and harmful materials while maintaining measurement capability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces direct mechanical measurement instruments with an optical measurement system consisting of a micro-alignment telescope and lens devices. This substitution allows non-contact measurement through the viewport, eliminating the need for physical instruments to be placed inside the vacuum chamber and exposed to harmful environmental conditions

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If outer deformation of the vacuum chamber is measured to infer inner deformation, then measurement simplicity is improved, but measurement precision deteriorates due to chamber wall deformation complexity

Engineering Contradiction:

Improvemeasurement simplicityVSAvoiddeformation measurement precision

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent extracts the measurement function from the vacuum chamber structure itself by using a separate optical measurement system positioned outside the chamber. Instead of relying on the chamber wall deformation to indicate internal component displacement, the system directly measures the accelerating tube position through the viewport, separating the measurement function from the structural deformation

Inventive Principle:

Principle #2Taking out (Extraction)

3Manufacturing precision

If the accelerating tube is precisely installed in the vacuum chamber in the atmosphere, then initial positioning accuracy is improved, but position accuracy deteriorates as the chamber contracts in vacuum causing the tube to move out of the correct position

Engineering Contradiction:

Improveinitial positioning accuracyVSAvoidposition accuracy in vacuum

Core Design Contradiction:

Manufacturing precisionVSMeasurement precision

Solution Approach 1:

The patent implements a feedback measurement system that continuously monitors the accelerating tube position after vacuum chamber contraction. The micro-alignment telescope measures the actual position of the accelerating tube in the vacuum state, providing feedback information about the displacement caused by chamber contraction, which can then be used to correct or compensate for the position error

Inventive Principle:

Principle #23Feedback
