Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a user controls calls on multiple electronic devices separately, then each device can be managed independently, but the operation complexity and time consumption increase significantly

Engineering Contradiction:
Improvecall control operationVSAvoidtime for managing multiple devices
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The wearable device is designed to universally control multiple electronic devices (mobile phone, tablet, computer) through a unified interface. The call control functionality is extended beyond the wearable device itself to manage calls on all connected devices, allowing the user to answer, decline, or transfer calls from any device through the wearable device's interface, eliminating the need to operate each device separately

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

Solution Approach 2:

The wearable device acts as an intermediary between the user and multiple electronic devices. It receives control inputs from the user and relays them to the appropriate target device for call management. The system establishes communication connections between the wearable device and multiple electronic devices, enabling the wearable device to mediate call control operations across different devices, thereby simplifying user interactions

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the wearable device integrates control for multiple devices, then call management becomes more convenient, but the device complexity increases

Engineering Contradiction:
Improvemulti-device control capabilityVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wearable device incorporates universal control capabilities that enable it to manage calls on multiple different types of electronic devices. The system establishes communication connections with multiple devices and uses device identification information to determine which device received an incoming call, allowing the wearable device to adaptively control any connected device through a unified interface

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

Solution Approach 2:

The system segments the control architecture by separating the control function (wearable device) from the audio output function (electronic devices). The wearable device handles call control operations while electronic devices handle audio playback, with the system determining the target device based on communication connections and device identification information

Inventive Principle:
Principle #1Segmentation
