Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electronic device periodically performs data communication with cloud server to maintain connection, then the network connectivity is maintained, but the power consumption increases and battery life is shortened

Engineering Contradiction:
Improvenetwork connectivityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent introduces a shared device as an intermediary that handles data transmission on behalf of the electronic device. The shared device maintains network connectivity with cloud servers while the electronic device can enter low-power states, thus maintaining reliability without continuous power consumption from the electronic device itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the communication function by separating the electronic device from the shared device. The shared device handles periodic data communication with cloud servers, while the electronic device focuses on local operations and Bluetooth scanning, reducing overall power consumption while maintaining network connectivity.

Inventive Principle:
Principle #1Segmentation

2Use of energy by moving object

If the electronic device uses Bluetooth to scan and connect with other devices for data transmission, then the power consumption is reduced, but the device complexity increases due to multi-device management

Engineering Contradiction:
Improvepower consumptionVSAvoidmulti-device management
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The shared device acts as an intermediary that simplifies multi-device management. It handles the complexity of maintaining connections with multiple electronic devices and cloud servers, while electronic devices only need to perform simple Bluetooth scanning and data transmission to the shared device, reducing individual device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The shared device is designed with multi-functionality to serve multiple electronic devices simultaneously. It can manage connections with multiple devices, perform data transmission to cloud servers, and handle authentication, thus reducing the need for each electronic device to have complex communication capabilities.

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