Head-Mounted Lens Seat Assembly for Corrective Lens Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display devices require users with vision issues to manually assemble and align corrective lenses, leading to inconvenience and potential damage during the process.
Innovation Solution
A head-mounted display device with elastic retraction portions and combining portions in the lens seats that allow easy assembly and positioning of user-prepared corrective lenses, maintaining consistent gaps for optimal visual experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually assemble and align corrective lenses with lens frames, then vision correction can be achieved, but the assembly process becomes complex and may cause damage to lenses
Solution Approach 1:
The lens seat incorporates an elastic retraction portion that automatically pushes the combining portion of the lens during assembly, enabling the structure to perform the alignment action itself without requiring manual intervention. This self-service mechanism simplifies the assembly process while maintaining precision.
Solution Approach 2:
The elastic retraction portion acts as an intermediary element between the lens seat and the lens. It mediates the assembly process by providing a controlled pushing force through the combining portion, facilitating smooth alignment and connection without direct manual manipulation of the lens.
2Productivity
If corrective lenses are manually assembled into lens frames, then vision correction is achieved, but time is lost during the assembly process
Solution Approach 1:
The lens seat is pre-configured with the elastic retraction portion and combining portions in the correct positions before assembly. This preliminary preparation ensures that when a lens is installed, the alignment and connection actions occur automatically and rapidly without requiring time-consuming manual adjustment steps.
3Manufacturing precision
If lens frames are assembled to the device, then corrective lenses can be positioned, but alignment issues arise between lens frames and the device
Solution Approach 1:
The combining portion and elastic retraction portion work together to enable the lens to self-align with the lens seat during assembly. The elastic retraction portion automatically pushes the lens into the correct position, eliminating the need for complex external alignment procedures and ensuring precise positioning.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy and damage-free assembly of user-prepared corrective lenses, ensuring consistent visual experience and preventing light leakage, while accommodating different user needs for vision correction.
Implementation Method 1
after the third combining portion of the first lens pushes away and passes through the first elastic retraction portion, the first elastic retraction portion is restored, the third combining portion is combined with the first combining portion, and a gap is maintained between the first lens and the first optical lens set

AI summary
A head-mounted display device includes a body and two optical lens sets. The optical lens sets are installed in the body and correspond to two lens seats of the body. When a lens is assembled to the lens seat of the body, a combining portion of lens pushes away and passes through an elastic retraction portion of a combining portion of the lens seat, the elastic retraction portion is restored, the combining portion of the lens is assembled with the combining portion of the lens seat, and a gap is maintained between the lens and the optical lens set.
