Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If additional devices and software installations are used to measure Wi-Fi bandwidth, then measurement accuracy is improved, but device complexity and operational difficulty increase

Engineering Contradiction:
ImproveWi-Fi bandwidth measurement accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The electronic device performs Wi-Fi bandwidth measurement using its own built-in communication circuitry and processor, without requiring external measurement devices. The device collects network parameters through its existing wireless communication interface and calculates bandwidth independently, embodying the self-service principle where the system measures itself rather than requiring separate measurement equipment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The built-in communication circuitry serves dual purposes: it performs both normal Wi-Fi communication functions and bandwidth measurement functions. The processor handles both general device operations and network parameter analysis, eliminating the need for dedicated measurement hardware and reducing overall system complexity while maintaining measurement capability.

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

2Measurement precision

If additional devices and software installations are used to measure Wi-Fi bandwidth, then measurement capability is improved, but ease of operation deteriorates

Engineering Contradiction:
ImproveWi-Fi bandwidth measurement accuracyVSAvoidoperational simplicity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The bandwidth measurement function is integrated into the device's existing operating system and communication stack. Users can initiate measurements through the device's interface without needing to install additional software or configure external equipment, making the operation as simple as any native device function while maintaining accurate measurement capabilities.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If additional devices are used to measure Wi-Fi bandwidth, then measurement accuracy is improved, but cost increases

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The device utilizes its existing communication hardware resources for self-diagnosis. The built-in wireless communication circuitry, processor, and memory are leveraged to perform bandwidth measurements that would traditionally require external equipment, thereby eliminating additional hardware costs while maintaining measurement functionality.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Existing communication hardware is made multi-functional by enabling it to perform both standard Wi-Fi communication and bandwidth measurement tasks. This eliminates the need for separate dedicated measurement devices, reducing hardware quantity and cost while preserving measurement accuracy through proper utilization of existing capabilities.

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