Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a new input device is added to the user terminal, then the functionality and versatility of the system is improved, but the device complexity and requirement for hardware/software updates increases

Engineering Contradiction:

Improvecompatibility with input devicesVSAvoidhardware and software updates

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an input signal converting device as an intermediary component between the input device and user terminal. This converter receives input signals from various input devices, converts them into compatible signals, and transmits them to the user terminal. This mediator approach allows multiple input devices to be supported without modifying the user terminal hardware or software, thus improving versatility while avoiding increased device complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the signal conversion function into a separate, independent input signal converting device rather than integrating it into the user terminal. This segmentation allows the conversion functionality to be added without increasing the complexity of the main user terminal system. The converter handles the complexity of signal adaptation independently, enabling the user terminal to remain simple while supporting multiple input devices.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If hardware and software are updated for each new input device, then compatibility with the new device is improved, but the loss of time and development effort increases

Engineering Contradiction:

Improvecompatibility with input devicesVSAvoiddevelopment time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The input signal converting device performs signal conversion in advance, transforming input signals from various devices into a standardized format that the user terminal can process. This preliminary conversion action eliminates the need for repeated hardware and software updates whenever new input devices are added, as the converter handles the adaptation work beforehand, saving significant development time and effort.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The input signal converting device autonomously handles the signal conversion process without requiring manual intervention or updates to the user terminal. The converter independently adapts to different input devices and performs the necessary signal transformations, making the system self-sufficient and eliminating the time-consuming process of updating user terminal hardware and software for each new device.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If the user terminal is modified to support new input devices, then the adaptability is improved, but the reliability and stability of the existing system decreases

Engineering Contradiction:

Improvecompatibility with input devicesVSAvoidsystem stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

By introducing the input signal converting device as an intermediary layer, the patent protects the user terminal from direct modifications. The converter handles all adaptations to new input devices, allowing the user terminal to remain unchanged and maintain its proven stability and reliability. The mediator absorbs the complexity of device variations while preserving the core system's integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the system into two independent parts: the user terminal and the input signal converting device. This segmentation ensures that modifications to support new input devices occur only in the converter, leaving the user terminal untouched. As a result, the user terminal's reliability and stability are preserved while the converter provides the necessary adaptability.

Inventive Principle:

Principle #1Segmentation
