Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex fixing systems are used to anchor position detectors, then anchoring stability is improved, but device complexity and operation time increase

Engineering Contradiction:

Improveanchoring stabilityVSAvoidfixing system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical fixing systems with a magnetic anchoring system. The position detector incorporates a magnet that interacts with a ferromagnetic material in the support plane, eliminating the need for complex mechanical fasteners, bolts, or clamps while providing stable anchoring through magnetic attraction forces.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention extracts the essential anchoring function from complex mechanical systems and implements it through a simple magnetic mechanism. By taking out only the necessary anchoring capability and implementing it through magnetism, the system achieves stability without the complexity of traditional mechanical fixing systems.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If manual repositioning operations are performed to adjust position detectors, then adaptability to different vehicles is improved, but operation time and precision are worsened

Engineering Contradiction:

Improvevehicle type adaptabilityVSAvoidrepositioning time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The magnetic anchoring system provides dynamic adaptability through a height-adjustable foot mechanism. The position detector can be quickly adjusted to different heights and positions by moving the adjustable foot along the support plane, allowing adaptation to various vehicle types without time-consuming manual repositioning operations.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent replaces manual repositioning operations with a magnetic anchoring system combined with a height-adjustable foot. This substitution allows operators to quickly adjust and secure the position detector at different positions by simply moving the adjustable foot, which is then held in place by magnetic attraction, eliminating the need for complex manual adjustment and securing operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If manual repositioning operations are performed to adjust position detectors, then adaptability to different vehicles is improved, but alignment precision is worsened

Engineering Contradiction:

Improvevehicle type adaptabilityVSAvoidalignment precision

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent replaces manual repositioning operations with a magnetic anchoring system that provides stable and precise positioning. The magnetic attraction forces hold the position detector firmly at the adjusted position, eliminating the imprecisions and instabilities associated with manual repositioning while maintaining adaptability through the height-adjustable foot mechanism.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If easily removable anchoring is implemented, then ease of operation is improved, but anchoring stability may be worsened

Engineering Contradiction:

Improveanchoring easeVSAvoidanchoring stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent uses magnetic anchoring to replace complex mechanical fixing systems, achieving both ease of operation and anchoring stability. The magnetic attraction provides firm holding power that ensures stable anchoring, while the simple magnetic interaction allows for easy removal and repositioning without the need to disassemble mechanical fasteners or deal with complex securing mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
