Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a mobile device is held during active tasks, then the device can be operated, but the device may be dropped or damaged

Engineering Contradiction:

Improvedevice operationVSAvoiddevice safety

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

A wearable control device worn on the user's body serves as an intermediary to control the mobile device remotely, eliminating the need to hold the mobile device during active tasks while maintaining operational capability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Physical contact with the mobile device is replaced by wireless communication between the wearable control device and the mobile device, allowing operation without mechanical holding

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Volume of moving object

If a wearable control device is designed to be compact, then it can be comfortably worn, but the display unit and control functions may be limited

Engineering Contradiction:

Improvewearable device sizeVSAvoidcontrol functionality

Core Design Contradiction:

Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The wearable control device integrates multiple functions including display unit, touch input, button input, and wireless communication in a single compact form factor, allowing it to perform various control operations despite its small size

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple control interfaces (touchscreen and physical buttons) and communication functions are merged into a single wearable device that can control various external devices including mobile phones, tablets, and computers

Inventive Principle:

Principle #5Merging (Combining)
