Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a movable detector is used to examine various body positions, then the adaptability and application scenarios are improved, but the alignment precision and positioning accuracy between the head and detector deteriorate

Engineering Contradiction:

Improveapplication scenariosVSAvoidpositioning accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent replaces the traditional mechanical positioning system with an electromagnetic positioning system using base stations and tags. The base station transmits electromagnetic signals to tags on the detector and head, calculating spatial positions through signal processing rather than mechanical linkages, enabling precise tracking of movable components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces base stations and tags as intermediary elements between the head and detector. These intermediaries establish a communication bridge that enables indirect positioning and alignment through electromagnetic signal exchange, allowing the system to track and maintain proper positioning without direct mechanical connection.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the detector is not confined to a specific location, then the flexibility for various body positions is improved, but the alignment control between head and detector becomes more difficult

Engineering Contradiction:

ImproveflexibilityVSAvoidalignment control

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a feedback control system where the controller continuously receives position information from the positioning system and automatically adjusts the detector or head position to maintain proper alignment. This closed-loop feedback mechanism simplifies operation while ensuring accurate alignment despite the detector's mobility.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces complex mechanical alignment mechanisms with an electromagnetic positioning and control system. The base station-tag electromagnetic field interaction provides non-contact positioning, eliminating the need for complex mechanical alignment devices while maintaining flexibility.

Inventive Principle:

Solution Approach 1:

The patent makes the base station multi-functional by integrating both electromagnetic signal transmission for positioning and alignment control functions into a single device. This universal design reduces overall system complexity despite adding positioning capabilities, as one component serves multiple purposes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces compact tags as lightweight intermediary elements attached to the detector and head. These small tags serve as simple position indicators that work with the base station to provide precise positioning without adding significant complexity to the main imaging system.

Inventive Principle:

Principle #24Intermediary (Mediator)
