Solution Overview

Problem

Head mounted display devices require varying clamping forces for different usage scenarios, and a single fixing method is not universally applicable, with existing devices becoming unusable if the temples are damaged.

Innovation Solution

A detachable fixing component design for head mounted display devices, allowing the first and second brackets to be replaced or swapped with other components based on usage needs, ensuring the device can be adapted for different scenarios and extended use without scrapping the entire device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single fixing method is used for the brackets, then the device structure is simple, but the device cannot adapt to different usage scenarios requiring varying clamping forces

Engineering Contradiction:

Improveadaptability to different usage scenariosVSAvoiddevice structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into a host and detachable bracket components. The brackets can be separated from the host and replaced independently, allowing different bracket types to be used for different usage scenarios without changing the entire device structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The host is designed with universal connection interfaces that can accommodate multiple types of brackets. This allows a single host to support various fixing methods and clamping forces by simply changing the bracket component.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If the brackets are fixed permanently to the host, then the device structure is stable, but the entire device becomes unusable if the brackets are damaged

Engineering Contradiction:

Improvedevice usabilityVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The connection between brackets and host is designed as detachable rather than permanent. This segmentation allows the brackets to be replaced independently when damaged, preserving the host and other components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

When brackets are damaged, only the bracket component needs to be discarded and replaced, while the host and other components are recovered and continue to be used, reducing waste and repair costs.

Inventive Principle:

Principle #34Discarding and recovering

3Ease of repair

If the brackets are made detachable for replacement, then the device can be repaired and adapted, but the connection stability and electrical connection reliability may be affected

Engineering Contradiction:

Improvebracket replaceabilityVSAvoidconnection stability

Core Design Contradiction:

Ease of repairVSReliability

Solution Approach 1:

The connection interface is pre-designed with alignment features and locking mechanisms that ensure proper positioning and stable connection when brackets are attached to the host.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A connection interface acts as an intermediary between the bracket and host, providing both mechanical attachment and electrical connection functions through a standardized interface design.

Inventive Principle:

Principle #24Intermediary (Mediator)
