Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a manually actuatable adjusting wheel is integrated into the actuator housing, then manual actuation is enabled, but spatial isolation is complex and costly

Engineering Contradiction:

Improvemanual actuation capabilityVSAvoidsupplemental constructions for spatial isolation

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the traditional mechanical coupling mechanism with an electrical coupling system. A generator is coupled to the manual actuating element, and this generator is electrically connected to the control unit of the actuator. This substitution eliminates the need for complex mechanical isolation constructions while enabling manual actuation through electrical signals generated by the generator.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the manual actuating element from the actuator housing, allowing it to be positioned separately in space. The manual actuating element can be located in a different position than the actuator itself, connected only through the electrical coupling via the generator. This extraction simplifies the overall construction by removing the need for integrated mechanical isolation structures.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If complex supplemental constructions are used for spatial isolation, then manual actuation is isolated from motor operation, but manufacturing costs increase

Engineering Contradiction:

Improveisolation of hand operation and motor operationVSAvoidmanufacturing costs

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces complex mechanical isolation constructions with a simple electrical coupling system. The generator serves as both the coupling mechanism and the isolation barrier, converting mechanical input from the manual actuating element into electrical signals that the control unit processes. This approach achieves reliable isolation between manual and motor operations while dramatically reducing manufacturing complexity and costs.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the manual actuating element is spatially isolated, then accessibility and safety are improved, but mechanical connection complexity increases

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical connection constructions with an electrical coupling system. The generator acts as an intermediary that converts mechanical rotation from the manually actuatable element into electrical energy, which is then transmitted to the control unit. This allows the manual actuating element to be positioned anywhere within electrical range of the actuator, greatly improving accessibility while eliminating the need for complex mechanical linkages.
