Innovation Solution

A modular wearable electronic device system featuring a head-mounted display with a removable electronic strap that includes a unique identifier, allowing the device to detect and apply user-specific settings and communicate with external devices through an antenna, enabling customizable and immersive VR/MR experiences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional VR/MR devices are used as stand-alone devices, then device simplicity is maintained, but the capability to create immersive and customized VR/MR environments is limited

Engineering Contradiction:

Improvecapability to create immersive and customized VR/MR environmentsVSAvoiddevice coordination and communication requirements

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wearable device is divided into separate functional modules: a head-mounted display unit and removable electronic straps. Each strap can independently communicate with external devices, allowing the system to achieve enhanced versatility through modular coordination rather than integrating all communication capabilities into the main device unit.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Electronic straps serve as intermediary components between the head-mounted display and external electronic devices. The straps contain communication modules that facilitate data exchange and coordination, enabling the stand-alone device to indirectly connect with external systems through these mediator elements.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If user specific settings are manually configured for each use case, then customization capability is achieved, but user convenience deteriorates due to the effort required to change settings

Engineering Contradiction:

Improveuser convenience in changing settingsVSAvoidtime required to change settings for different use cases

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The electronic strap automatically performs the function of configuring user settings without requiring manual intervention. When the strap is attached to the device, it autonomously communicates with external devices, retrieves appropriate settings, and applies them to the head-mounted display, thereby serving itself rather than requiring user configuration.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

User settings are pre-configured and stored on the electronic strap or associated external devices before the user needs them. When the strap is attached, the settings are already prepared and can be automatically applied immediately, eliminating the need for real-time configuration during use.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If wearable devices lack communication capabilities with external devices, then device simplicity is maintained, but the quality and variety of VR/MR experiences are limited

Engineering Contradiction:

Improvequality and variety of VR/MR experiencesVSAvoidcommunication and coordination functionality

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Communication functionality is segmented into separate electronic strap modules rather than being integrated into the main head-mounted display. This allows the core device to remain relatively simple while optional straps provide enhanced communication capabilities when needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The electronic straps are designed as universal components that can communicate with multiple types of external devices (audio equipment, computing devices, etc.). A single strap design can facilitate connections to various external systems, providing multi-functionality without requiring separate specialized components for each device type.

Inventive Principle:

Principle #6Universality (Multi-functionality)
