Solution Overview

Problem

The sealing effect between the lens barrels and the bottom plate of VR glasses is reduced, leading to a decrease in clarity due to dust and moisture ingress, which affects the user experience.

Innovation Solution

Incorporation of silicone-based sealing parts with bellows-type structures that deform to accommodate adjustable lens barrel spacing, along with mechanical mechanisms for precise alignment and sealing enhancement, including gears and sliding plates, to maintain a secure fit and prevent dust ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the lens barrels are adjusted to different positions to accommodate varying interpupillary distances, then the adaptability to different users is improved, but the sealing effect between lens barrels and bottom plate deteriorates, allowing dust ingress

Engineering Contradiction:
Improveadjustability of lens barrel spacingVSAvoidsealing effect
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent employs silicone sealing parts with bellows-type structures that can flexibly deform as the lens barrels move between different positions. This flexible membrane structure maintains sealing effectiveness while accommodating the range of motion required for interpupillary distance adjustment, resolving the contradiction between adaptability and sealing reliability

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The sealing structure is designed to be dynamic rather than static, with the bellows-type silicone parts capable of continuous deformation to match the moving lens barrels. This dynamic sealing mechanism ensures that the sealing effect is maintained across all adjustable positions, allowing the system to adapt while preserving reliability

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the lens barrels are continuously adjusted during use, then the ease of operation is improved, but the sealing structure is more prone to damage, reducing reliability

Engineering Contradiction:
Improveadjustability during useVSAvoidsealing structure durability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The silicone material's inherent flexibility and elasticity allow the sealing parts to withstand continuous adjustment operations without cracking or failing. The bellows-type structure is specifically designed to endure repeated deformation cycles while maintaining sealing integrity, thus supporting ease of operation without compromising reliability

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The sealing structure is designed with sufficient deformation space and flexibility beforehand to accommodate user adjustments without reaching critical stress points. This pre-engineered cushioning capacity allows continuous operation while preventing damage to the sealing structure

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
