Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a soil penetrating device is driven into the ground to detect submerged objects, then the location of objects can be determined, but it is unclear whether the device hit an object of interest or other underground features like tree roots or rocks

Engineering Contradiction:
Improveobject identification accuracyVSAvoidobject type information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent replaces the purely mechanical soil penetrating device with a hybrid system that incorporates optical imaging technology. The imaging device captures visual information of the underground environment, allowing users to identify object types (pipes, cables, tree roots, rocks) without relying solely on mechanical feedback. This substitution of mechanical detection with optical detection resolves the contradiction by providing both location and identification information simultaneously.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The imaging device acts as an intermediary between the soil penetrating device and the user. Instead of directly interpreting mechanical resistance or depth information, users observe visual images captured by the imaging device. This intermediary provides detailed information about the underground environment, enabling accurate identification of object types while maintaining the simplicity of the penetration operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the soil penetrating device is driven deep into the ground to locate submerged objects, then detection capability is improved, but the device becomes difficult to retrieve and operation becomes more complex

Engineering Contradiction:
Improvedetection capabilityVSAvoiddevice retrieval ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The hollow cylinder structure serves multiple functions: it contains and directs the pressurized liquid jet for soil loosening, houses the imaging device for visualization, and acts as the penetrating lance itself. This multi-functionality reduces the need for separate retrieval mechanisms while maintaining deep detection capability, as the same structure used for penetration and imaging also facilitates recovery through the liquid jet system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If pressurized liquid is ejected from the liquid outlet to loosen soil, then penetration ease is improved, but the device complexity increases

Engineering Contradiction:
Improvesoil penetration easeVSAvoidliquid ejection system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the liquid ejection system with the hollow cylinder structure of the penetrating device. The liquid inlet and outlet are integrated into the cylinder walls, and the imaging device is positioned within the same hollow space. This merging eliminates the need for separate external liquid delivery systems and reduces overall device complexity while maintaining the soil-loosening function.

Inventive Principle:
Principle #5Merging (Combining)
