Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the display and input devices are made smaller to fit wearable form factor, then the device portability and wearability are improved, but the user interface controllability and ease of operation deteriorate

Engineering Contradiction:
Improvedevice sizeVSAvoiduser interface controllability
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent introduces a separate control entity (such as a remote control device or mobile device) that acts as an intermediary between the user and the wearable device. This external control entity provides a larger, more convenient interface for user interaction while the wearable device maintains its compact form factor. The control entity communicates with the wearable device wirelessly to execute commands and adjust settings.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extends the user interface interaction from the two-dimensional limited display of the wearable device to a three-dimensional spatial interaction model. By using proximity detection and spatial positioning, users can interact with the wearable device through gestures and movements in space, effectively adding a new dimension of interaction that compensates for the limited physical interface on the small device.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If more input controls are added to the wearable device, then the user interface functionality is improved, but the device complexity and size increase

Engineering Contradiction:
Improveuser interface functionalityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex input control functions from the wearable device and relocates them to an external control entity. This allows the wearable device to maintain its simplicity and compact design while still providing comprehensive user interface functionality through the external device that handles all complex input operations, processing, and control logic.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent makes the external control entity serve multiple functions: it acts as a remote control, a settings interface, a notification device, and a command processor for the wearable device. This multi-functional approach allows comprehensive user interface capabilities to be achieved without adding corresponding complexity to the wearable device itself, as the external entity handles diverse tasks.

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