Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional antenna arrays are mounted on vehicles, then they provide fixed monitoring capabilities, but they lack flexibility for different measurement scenarios

Engineering Contradiction:

Improvemeasurement scenario flexibilityVSAvoidantenna configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The antenna system is divided into separate, independently attachable antenna elements that can be selectively positioned and configured. Each antenna can be attached or detached from the vehicle surface independently, allowing flexible reconfiguration for different measurement scenarios without requiring complex integrated systems.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The antenna array transitions from a fixed configuration to a dynamic, reconfigurable system. Magnets enable antennas to be easily attached, detached, and repositioned on the vehicle surface, allowing the system to adapt its configuration based on different measurement requirements and scenarios.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple antennas are permanently mounted on a vehicle, then monitoring coverage is extended, but the system cannot be easily reconfigured for different purposes

Engineering Contradiction:

Improvemeasurement purpose flexibilityVSAvoidconfiguration change ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Magnets are pre-installed on the vehicle surface at optimal positions for different measurement scenarios. This preliminary preparation allows antennas to be quickly attached and positioned without requiring complex installation procedures or tools, enabling rapid reconfiguration between different measurement purposes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Traditional mechanical fastening systems (screws, clips, adhesives) are replaced with magnetic attachment. This substitution eliminates complex mechanical assembly and disassembly processes, allowing antennas to be easily attached and repositioned by simply bringing them near the magnetic surfaces, significantly improving operational ease.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If antennas are magnetically attached to a surface, then flexible attachment and detachment is enabled, but the attachment strength must be sufficient to withstand vehicle conditions

Engineering Contradiction:

Improveattachment and detachment easeVSAvoidattachment strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

Different magnet strengths and distributions are used at different locations on the vehicle surface based on local requirements. Areas subject to higher vibration or movement use stronger magnets, while less critical areas use weaker magnets for easier attachment. This localized optimization ensures sufficient attachment strength where needed while maintaining ease of operation elsewhere.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The attachment system uses composite magnetic structures combining different magnetic materials and configurations. This allows the system to achieve both strong attachment force for withstanding vehicle conditions and controlled detachability when needed, balancing strength and ease of operation through material composition rather than relying on a single magnetic strength level.

Inventive Principle:

Principle #40Composite materials
