Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed headgear configuration is used, then the structure is simple and easy to manufacture, but the user experience is inconsistent and comfort is compromised

Engineering Contradiction:

Improvecustomizability of headgear fitVSAvoidcomplexity of headgear structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The headgear is divided into modular components including a crown strap with bridge regions, side straps, and an interface assembly. Each component can be independently adjusted or removed, allowing users to customize the fit while maintaining a manageable overall structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The headgear incorporates adjustable elements such as movable bridge regions, reconfigurable strap connections, and flexible attachment mechanisms. These dynamic features enable users to modify the headgear configuration to achieve optimal comfort and fit for different users and situations.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple adjustable components are added to the headgear, then user comfort and customization are improved, but the ease of operation deteriorates

Engineering Contradiction:

Improveadjustability of crown strapVSAvoidease of headgear assembly

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The headgear components are designed with pre-configured attachment points, alignment features, and intuitive connection mechanisms. The bridge regions and strap connections are prepared in advance to guide users through simple assembly steps, reducing the operational complexity despite the multiple adjustable features.

Inventive Principle:

Principle #10Preliminary action

3Stability of the object's composition

If the crown strap is made from non-stretchable material, then the structural stability is improved, but the adaptability to different head shapes deteriorates

Engineering Contradiction:

Improvestructural stability of crown strapVSAvoidadaptability to user anatomy

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The crown strap is divided into multiple bridge regions and strap sections that can be independently positioned and adjusted. This segmentation allows the non-stretchable material to maintain structural stability while the modular configuration adapts to different head shapes and sizes through repositioning rather than stretching.

Inventive Principle:

Principle #1Segmentation

AI summary

An interface and headgear assembly includes a headgear assembly. The headgear assembly has a first strap configured to connect to the interface. A crown strap can be adjusted along a length of the first strap. In some configurations, the crown strap has a first portion and a second portion that are adjustably connected. The crown strap can be removably connected to the first strap using bridge regions of the first portion and the second portion.
