Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual or semi-automatic handling of solid targets is used, then device complexity is reduced, but operator exposure to activated targets increases and productivity decreases

Engineering Contradiction:
Improvetarget handling efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

A pneumatic tube transport system acts as an intermediary between the target processing point and the particle accelerator. The system uses sealed capsules that are pneumatically transported through tubes, eliminating the need for direct manual handling of activated targets while maintaining operational simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The handling mechanism extracts the solid target from the capsule and transfers it to the target positioning device. This separation of functions allows the transport system to remain simple while enabling automated target handling and positioning.

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of time

If manual transport of shielding box is used, then equipment cost is reduced, but time consumption increases and operator safety is compromised

Engineering Contradiction:
Improvetarget transport timeVSAvoidoperator exposure to radiation
Core Design Contradiction:
Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The pneumatic tube system serves as a mediator that transports sealed capsules containing activated targets without requiring operator intervention during transit. The system provides both speed and radiation protection simultaneously through automated pneumatic transport of closed containers.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If automated handling mechanism is implemented, then operator safety is improved, but device complexity increases

Engineering Contradiction:
