Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple sensing devices are employed to improve sensing accuracy, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvesensing information accuracyVSAvoidnumber of sensing devices
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Multiple sensing devices with the same function are merged into a function group with a unified identifier. The group manages communication and data aggregation collectively, reducing individual device complexity while maintaining enhanced sensing accuracy through coordinated operation of multiple devices.

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If a plurality of sensing devices communicate independently, then information transmission accuracy is improved, but energy consumption increases

Engineering Contradiction:
Improveinformation transmission accuracyVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

A master sensing device is designated as an intermediary within each function group to manage communication with external devices. Slave sensing devices communicate only with the master, which aggregates and relays data externally. This mediator structure maintains accurate information transmission while significantly reducing the energy consumption of individual slave devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Use of energy by moving object

If sensing devices are grouped into function groups with master and slave designations, then energy consumption is reduced, but device complexity increases

Engineering Contradiction:
Improveenergy consumptionVSAvoidcommunication management structure
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The master sensing device performs multiple functions including receiving operation parameters from external devices, managing communication protocols, aggregating data from slave devices, and relaying information externally. This multi-functional design consolidates complexity into a single device while allowing slave devices to maintain simpler, energy-efficient operations.

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

4Use of energy by moving object

If sensing devices aggregate data before transmission, then energy consumption is reduced, but information transmission accuracy may deteriorate

Engineering Contradiction:
Improveenergy consumptionVSAvoidsensed information accuracy
Core Design Contradiction:
Use of energy by moving objectVSMeasurement precision

Solution Approach 1:

The master sensing device receives operation parameters and commands from external devices, processes them, and relays appropriate instructions to slave devices. This feedback mechanism ensures that aggregation and processing operations maintain the accuracy requirements specified by external systems while still achieving energy savings through coordinated data management.

Inventive Principle:
Principle #23Feedback

AI summary

A grouping method for a sensing device is provided. The sensing device includes a sensor, a processor, storage and a communication device controlled by the processor. The method includes: inquiring the sensing device's sensing function, supported network types; exchanging the inquired information with other sensing devices having a same sensing function and in networks of same supported network types; forming a function group based on a pre-defined first rule, and exchanging first configuration parameters within the function group; designating one of the sensing devices of the group a master sensing device, and rest of the group slave sensing device(s) based on the exchanged first configuration parameters and a pre-defined second rule; and controlling the master sensing device's the communication device to receive operation parameters and commands from a device outside the function group and relaying the operation parameters and commands to the rest of the function group.
