Adjustable Distance Structure for Wearable Display Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical wearable electronic devices are manufactured in a uniform appearance, failing to account for varying head shapes and inter pupillary distances (IPDs) of users, leading to issues such as distorted images and dizziness.
Innovation Solution
A wearable electronic device featuring a distance adjustment structure, comprising a first and second housing with protrusions, and a circular plate with a spiral recess, allowing the distance between the display devices to be adjusted to accommodate different user head sizes and IPDs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a uniform appearance is used for wearable electronic devices, then manufacturing complexity is reduced, but the device cannot accommodate varying head shapes and inter pupillary distances, leading to distorted images and dizziness
Solution Approach 1:
The patent implements an adjustable distance structure that allows the separation between left and right display devices to be dynamically changed. This enables the device to adapt to different inter pupillary distances of users, resolving the contradiction between uniform manufacturing and individualized accommodation. The adjustable mechanism maintains image clarity and prevents dizziness by matching the display separation to each user's specific IPD.
2Device complexity
If the distance between display devices is fixed, then device structure is simplified, but the optical path may warp and images become distorted when users have different head sizes
Solution Approach 1:
The patent employs an adjustable distance structure that enables dynamic modification of the separation between display devices. This dynamic adjustment capability allows precise optical path alignment for users with different head sizes and inter pupillary distances, preventing image distortion and warping while maintaining reasonable device structure.
3Ease of manufacture
If the display devices are positioned according to a standard IPD, then device design is simplified, but users with non-standard IPDs experience improper focus and distorted images
Solution Approach 1:
The patent implements an adjustable distance structure that allows users to modify the separation between display devices to match their specific inter pupillary distance. This dynamic adjustment ensures that images are properly focused and clearly visible for users with non-standard IPDs, while maintaining simplified device design through a standardized adjustment mechanism.

AI summary
An electronic device is provided. The electronic device includes a first housing including a first display device and a first connection unit having a first protrusion formed thereon, a second housing including a second display device coupled to the first connection unit to be movable in a predetermined direction and a second connection unit having a second protrusion formed thereon, and a circular plate including a spiral recess, the circular plate being coupled to the first protrusion and the second protrusion. The circular plate is configured such that, by rotation of the circular plate, the first protrusion and the second protrusion move in a predetermined direction, and depending on the movement, a distance between the first housing and the second housing is adjustable.
