Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wired communication (UART, PM bus, CAN bus) is used to update product specifications, then parameter modification can be achieved, but the system requires physical cable connections and complex setup procedures

Engineering Contradiction:

Improveparameter modification processVSAvoidcable connection requirements

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical cable connection system with a wireless communication system. The parameter setting device communicates with the electronic device through wireless transmission modules, eliminating the need for physical cable connections while maintaining the ability to transmit specification parameters and control signals.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a parameter setting device as an intermediary between the user and the electronic device. This intermediary device contains wireless transmission modules that facilitate parameter communication without requiring direct physical connection to the electronic device, simplifying the overall system setup.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple cables are used to connect planning tool to multiple chargers and computer host, then parameter modification capability is maintained, but the cost and time of modifying products is greatly increased

Engineering Contradiction:

Improvemulti-device parameter modificationVSAvoidparameter modification time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The parameter setting device is designed with universal wireless communication capability that can connect to multiple electronic devices simultaneously or sequentially without requiring different cable connections for each device. The wireless transmission modules enable the same parameter setting device to efficiently modify parameters across multiple devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system allows specification parameters to be prepared and transmitted in advance through wireless communication. The parameter setting device can store and manage specification parameters, enabling quick deployment to multiple devices without the time-consuming process of physical cable connections for each device.

Inventive Principle:

Principle #10Preliminary action

3Ease of manufacture

If specification parameters are updated through wired planning tools, then product customization is achieved, but the process requires the device to be shut down and connected through physical cables

Engineering Contradiction:

Improveproduct specification updateVSAvoiddevice shutdown requirement

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent replaces the mechanical cable connection required during device shutdown with wireless communication that can operate independently of the device's power state. The wireless transmission modules enable parameter transmission without requiring the electronic device to be physically connected or shut down, streamlining the specification update process.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A wireless system for setting parameters includes at least one electronic device and a parameter-setting device. The electronic device has a first wireless transmission module, a processor, and a desirable device to be set. The processor is electrically connected to the first wireless transmission module and the desirable device. The parameter-setting device has a second wireless transmission module. The parameter-setting device is wirelessly connected to the processor and the desirable device through the first wireless transmission module and the second wireless transmission module. When the desirable device is shut down, the parameter-setting device transmits specification parameters to the first wireless transmission module through the second wireless transmission module to store the specification parameters into the first wireless transmission module. When the desirable device starts, the desirable device drives the processor to read the specification parameters and operates according to the specification parameters.
