Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If cable connections are used for power and data transmission, then electrical power can be transmitted, but the cable cross-section and length are fixed, limiting the available electrical power

Engineering Contradiction:
Improveelectrical powerVSAvoidpower scalability
Core Design Contradiction:
PowerVSAdaptability or versatility

Solution Approach 1:

The patent replaces the mechanical cable connection system with an inductive power transmission system using electromagnetic fields. The pipe inspection device includes a receiver coil that wirelessly receives power from a transmitter, eliminating the fixed cable constraints and enabling flexible power delivery without physical connection limitations.

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

2Power

If additional accumulators or batteries are added to increase power availability, then higher power can be provided, but the device complexity and weight increase

Engineering Contradiction:
Improvepower availabilityVSAvoidsystem complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The patent replaces heavy battery/accumulator systems with wireless inductive power transmission. Instead of carrying large energy storage devices within the pipe inspection unit, power is delivered wirelessly through electromagnetic coupling, significantly reducing device weight and complexity while maintaining high power availability.

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

Solution Approach 2:

The patent introduces an external power transmitter as an intermediary device that provides power wirelessly to the pipe inspection device. This external power source acts as a mediator, delivering energy without requiring physical connection or internal energy storage in the inspection device itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Power

If cable connections are used for charging, then power can be transmitted, but the cable interfaces require complex sealing to prevent gas and liquid penetration

Engineering Contradiction:
Improvepower transmissionVSAvoidsealing complexity
Core Design Contradiction:

Solution Approach 1:

The patent eliminates mechanical cable connections and their associated sealing requirements by implementing wireless inductive power transmission. The electromagnetic field coupling requires no physical penetrations through the device housing, completely removing the need for complex cable seals and interface protections.

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

4Ease of operation

If contact points or connector interfaces are provided for charging, then charging can be performed, but the contact points corrode quickly due to environmental conditions in pipes

Engineering Contradiction:

Solution Approach 1:

The patent replaces the mechanical accumulator removal and reinsertion process with wireless inductive charging. Power is transmitted through electromagnetic fields without requiring any opening or access to the device interior, eliminating the need for removable covers or seals on accumulator compartments.

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

6Ease of operation

If plug interfaces are provided for charging, then power transmission is enabled, but the interfaces become dirty and damaged during inspection or maintenance processes

Engineering Contradiction:
