Solution Overview

Problem

Existing virtual reality head-mounted displays are difficult for users to adjust and wear comfortably, affecting the overall user experience.

Innovation Solution

A flexible strap system for head-mounted displays, comprising non-stretchable and stretchable sections that wrap around the device and conform to different regions of the user's head, providing adjustable fit and comfort through split sections and integrated stretchable straps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing head-mounted display strap systems are used, then the device can be worn on the user's head, but the user experiences difficulty in adjusting and achieving comfortable wear

Engineering Contradiction:
Improveease of adjustmentVSAvoidfit for various head shapes
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The strap system is divided into multiple distinct sections: a first section wrapping around the display, second and third sections extending to the ears, and fourth and fifth sections extending to the back of the head. This segmentation allows each section to be independently adjusted and positioned to accommodate different head shapes and sizes, resolving the contradiction between ease of adjustment and adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The strap system incorporates dynamic adjustability through its modular structure, where sections can be moved, repositioned, and reconfigured. The fourth and fifth sections can be adjusted to extend to different locations on the back of the user's head, enabling the system to adapt to various head shapes while maintaining ease of adjustment through simple repositioning actions.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If existing strap systems are used, then the head-mounted display can be secured on the user's head, but the weight distribution causes pressure on the cheeks and nose

Engineering Contradiction:
Improvecomfortable wearingVSAvoidpressure on cheeks and nose
Core Design Contradiction:
Ease of operationVSStress or pressure

Solution Approach 1:

The strap system redistributes weight by adding spatial dimensions to the support structure. The fourth section extends to the back of the user's head, creating a new support dimension that transfers weight from the front (cheeks and nose) to the back of the head, thereby reducing pressure on sensitive areas while maintaining comfortable wear.

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

Solution Approach 2:

The strap system creates a counterbalancing structure where the fourth and fifth sections extending to the back of the head provide counterweight support. This counterbalancing arrangement offsets the weight of the head-mounted display, preventing excessive pressure on the cheeks and nose while ensuring comfortable wearing throughout extended use.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

AI summary

A strap system for a head-mounted display includes a first flexible non-stretchable section to wrap around the head-mounted display and extend laterally towards a user's ears, a second flexible non-stretchable section to extend from a first side of the first flexible non-stretchable section towards the back of the user's first ear and split into an upper portion and a lower portion, and a third flexible non-stretchable section to extend from a second side of the first flexible non-stretchable section to the back of the user's second ear and split into an upper portion and a lower portion. The upper portion of the second flexible non-stretchable section substantially mirrors the upper portion of the third flexible non-stretchable section. The lower portion of the second flexible non-stretchable section substantially mirrors the lower portion of the third flexible non-stretchable section.
