Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If frequency converters are adjusted during operation using traditional methods, then operating parameters can be set to desired values, but the adjustment process is cumbersome and requires manual intervention

Engineering Contradiction:

Improveconvenience of adjusting frequency converter parametersVSAvoidcomplexity of adjustment process

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical adjustment methods with wireless communication technology. WLAN modules enable parameter adjustment through wireless data transmission, eliminating the need for physical access to the frequency converter and manual configuration procedures. This substitution dramatically improves ease of operation while reducing adjustment process complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces WLAN modules as intermediary devices between the operator and the frequency converter. These modules handle wireless communication and data exchange, serving as a mediator that simplifies the adjustment process. The intermediary enables remote parameter modification without direct manual intervention, resolving the contradiction between ease of operation and device complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If frequency converters use wired data interfaces for parameter adjustment, then data exchange is reliable, but flexibility and remote control capability are limited

Engineering Contradiction:

Improveflexibility in parameter adjustmentVSAvoidremote control capability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements multi-functionality by equipping frequency converters with both wired data interfaces and wireless WLAN modules. This universal approach allows the system to maintain reliable wired connections when needed while also providing flexible wireless remote control capability. The dual-interface design enables adaptation to different operational scenarios, resolving the contradiction between reliability and flexibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces dynamic adaptability through WLAN modules that can be activated or deactivated based on operational requirements. The wireless interface provides dynamic remote control capability, allowing operators to adjust parameters remotely when needed while maintaining the option to use traditional wired methods. This dynamic approach enhances versatility without compromising ease of operation.

Inventive Principle:

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent enables preliminary configuration of frequency converter parameters through wireless communication. Operators can pre-set desired parameter values and transmit them wirelessly to the frequency converter, eliminating the need for time-consuming manual adjustment during operation. This preliminary action approach significantly improves productivity by reducing the time required for parameter changes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces time-consuming manual adjustment procedures with automated wireless parameter transmission. The WLAN modules enable rapid digital communication of configuration data, substituting the slow mechanical process of manual parameter setting. This substitution dramatically reduces adjustment time and improves operational efficiency, directly addressing the productivity-time loss contradiction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
