Wearable Device Detachable Optomechanical Module

Solution Overview

Problem

Wearable devices such as VR and AR glasses are prone to damage when dropped, leading to the entire device being scrapped due to the fragility of their optical components.

Innovation Solution

A wearable device design featuring a load-carrying device with detachably mounted optomechanical devices, allowing for easy replacement of optical components like display screens and optical assemblies, which are securely connected via connectors and can be fixed using screw or snap-fit mechanisms, enabling continued use without scrapping the entire device upon damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If optical components are integrated into the wearable device, then the device can perform VR/AR functions, but the entire device must be scrapped when optical components are damaged

Engineering Contradiction:

Improvedevice functionalityVSAvoiddevice replacement cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The wearable device is divided into separable modules: a load-carrying device and detachably mounted optomechanical devices. The optomechanical device can be separated from the load-carrying device, allowing independent replacement of damaged optical components without discarding the entire wearable device.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

When optical components are damaged, only the optomechanical device portion is replaced while the load-carrying device is retained and reused. This selective replacement approach recovers the valuable load-carrying device structure, electronics, and other non-optical components.

Inventive Principle:

Principle #34Discarding and recovering

2Ease of repair

If optical components are made detachable, then damaged components can be replaced, but the device structure becomes more complex

Engineering Contradiction:

Improvecomponent replaceabilityVSAvoidmounting structure

Core Design Contradiction:

Ease of repairVSDevice complexity

Solution Approach 1:

The wearable device is divided into separable modules: a load-carrying device and detachably mounted optomechanical devices. The optomechanical device can be separated from the load-carrying device, allowing independent replacement of damaged optical components without discarding the entire wearable device.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mounting structure uses universal connectors and interfaces that can accommodate different optomechanical device configurations. The load-carrying device is designed with standardized mounting points that can work with various optomechanical devices, reducing overall system complexity despite the detachable design.

Inventive Principle:

Principle #6Universality (Multi-functionality)
