Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple different types of ports are included in a device to allow coupling to a wide range of devices, then the adaptability of the device is improved, but the difficulty of detecting and measuring the correct port location increases

Engineering Contradiction:
Improvedevice compatibilityVSAvoidport location detection
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The detection circuitry performs preliminary detection of connector type and port compatibility before the user attempts connection. The system proactively identifies which port is compatible with the connector being approached, and provides indication signals to guide the user to the correct port location, eliminating the need for user trial-and-error.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

An intermediary indication system (visual, audio, or haptic signals) is introduced between the connector and the port. This intermediary provides information about compatibility, allowing the user to identify the correct port without direct observation or physical touch of the ports themselves.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If ports are placed in locations that are visually difficult to observe to improve device design flexibility, then the ease of manufacture is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improveport placement flexibilityVSAvoidport location identification
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent introduces an intermediary indication system that provides information about port compatibility without requiring the user to visually observe or physically touch the ports. The indication signals (visual, audio, or haptic) are provided at a distance from the ports, allowing users to identify the correct port location without needing to see or touch the ports themselves.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical approach of visually locating and manually identifying ports with an automated detection and indication system. The detection circuitry automatically detects connector type and determines compatibility, then provides signals to indicate the correct port location, substituting manual visual inspection with automated electronic detection and signaling.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If detection circuitry is added to identify compatible ports, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveconnector compatibility identificationVSAvoidcircuitry configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The detection circuitry is designed to be universally applicable across different connector types and port configurations. The same basic detection and indication mechanism can identify compatibility for various connector types (USB, HDMI, DisplayPort, etc.), reducing the need for separate specialized circuits for each connector type and thereby limiting the increase in overall device complexity.

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