Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display (HMD) devices are not sufficiently portable, accessible, and comfortable, often requiring separate carrying of communication terminals and experiencing shaking or tilting issues during use.
Innovation Solution
A head-mounted display apparatus integrated with a portable mobile communication terminal, featuring a main frame with a support part for fixing to the user's face, a position adjustment mechanism to prevent tilting, and a lens system for correcting visual acuity, allowing for comfortable and steady image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a head-mounted display apparatus integrates a portable mobile communication terminal, then portability and accessibility are improved, but device complexity increases
Solution Approach 1:
The patent combines a mobile communication terminal with a head-mounted display apparatus into a single integrated device. The terminal unit is mounted within the main body of the HMD, allowing users to have both display functionality and communication capabilities in one wearable device, eliminating the need to carry separate devices.
2Measurement precision
If the distance between the lens and the display is adjusted, then visual acuity correction is improved, but shaking or tilting occurs
Solution Approach 1:
The patent implements a dynamically adjustable lens-display distance mechanism that allows users to modify the spacing between the lens and display according to their visual needs. This adjustment mechanism is designed with stabilization features that prevent shaking or tilting during the adjustment process, maintaining image stability while enabling visual acuity correction.
