Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual assignment methods are used for wireless transmitters and receivers, then device complexity is reduced, but ease of operation deteriorates due to requiring manual intervention

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system enables automatic assignment where the wireless transmitter and receiver autonomously pair and establish communication without manual intervention. The transmitter automatically detects the receiver and initiates the assignment process, allowing the system to configure itself independently.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

A wireless assignment device serves as an intermediary between the transmitter and receiver, facilitating the assignment process. This mediator coordinates the pairing by managing the exchange of identification signals and establishing the communication link between the two devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If automatic assignment is implemented without a separate assignment device, then device complexity is reduced, but reliability deteriorates due to potential assignment errors

Engineering Contradiction:
Improvedevice complexityVSAvoidreliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The wireless assignment device acts as a reliable intermediary that coordinates the assignment process between transmitter and receiver. It manages the exchange of identification signals and ensures proper pairing, reducing assignment errors while maintaining relatively simple device architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system incorporates feedback mechanisms where the assignment device receives signals from both transmitter and receiver, processes the information, and provides confirmation signals to ensure successful assignment. This feedback loop verifies proper pairing and reduces reliability issues.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If multiple transmitters and receivers are supported, then adaptability is improved, but device complexity increases due to management requirements

Engineering Contradiction:

Solution Approach 1:

The wireless assignment device is designed with universal functionality to handle assignment of multiple transmitter-receiver pairs. It can manage various device types and configurations through a unified assignment process, enabling the system to adapt to different scenarios without requiring specialized hardware for each case.

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

Solution Approach 2:

The system segments the assignment process into distinct phases: signal transmission, identification exchange, and pairing confirmation. This segmentation allows the assignment device to efficiently manage multiple devices by processing assignments in discrete steps, reducing the complexity of simultaneous multi-device management.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If wireless assignment without physical connections is used, then ease of operation is improved, but measurement precision deteriorates due to signal interference

Engineering Contradiction:

Solution Approach 1:

The wireless assignment device serves as an intermediary that receives and processes identification signals from transmitters and receivers. It filters and validates the wireless signals to ensure accurate device identification, compensating for potential signal interference through error checking and verification protocols.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces physical connection-based identification with wireless signal-based identification. The assignment device uses electromagnetic signals to transmit and verify device identities, eliminating the need for physical connectors while implementing signal validation mechanisms to maintain identification accuracy.

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