Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual registration of wireless sensor device is used, then the unique network address can be recorded, but the process is time-consuming and inefficient

Engineering Contradiction:

Improvepairing efficiencyVSAvoidregistration time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical registration operations with an automated contact-based pairing system. When the wireless sensor device contacts the mobile device, sensors detect the contact event and automatically initiate pairing through code transmission, eliminating the need for manual address entry and significantly reducing registration time

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wireless sensor device performs self-registration by automatically transmitting its identification code to the mobile device upon contact. The device autonomously completes the pairing process without requiring user intervention to manually enter network addresses, thereby improving productivity and reducing time loss

Inventive Principle:

Principle #25Self-service

2Ease of operation

If wireless pairing is used, then manual intervention is reduced, but pairing can be ineffective and inaccurate due to signal interference

Engineering Contradiction:

Improvepairing operationVSAvoidpairing accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces a physical contact intermediary between the wireless sensor device and mobile device. This contact serves as a reliable trigger mechanism that initiates code transmission, ensuring accurate device identification and pairing without being affected by wireless signal interference from other devices

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces unreliable wireless signal-based pairing with a contact-based mechanical trigger system. The physical contact event reliably initiates the pairing process through sensor detection and code transmission, significantly improving pairing accuracy and effectiveness

Inventive Principle:

3Measurement precision

If manual registration with network address is used, then device identification is possible, but the process is complex and costly

Engineering Contradiction:

Improvedevice identification accuracyVSAvoidregistration process complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses a simplified code copy mechanism instead of complex network address handling. The wireless sensor device contains a unique identification code that is automatically transmitted to the mobile device upon contact, allowing accurate device identification through simple code reception rather than complex address management

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system replaces complex manual network address entry operations with a simple contact-based code transmission mechanism. This substitution maintains device identification accuracy while dramatically reducing process complexity and eliminating the need for users to manually handle network addresses

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
