Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed display unit position is used, then the device structure is simple, but it cannot accommodate users with different pupil distances
Solution Approach 1:
The display unit is made adjustable through a rotating shaft arm unit with multiple segments that can rotate and reposition. This dynamic structure allows the display unit to move to different positions, enabling accommodation of various pupil distances while maintaining a relatively simple overall device structure.
Solution Approach 2:
The rotating shaft arm unit is divided into multiple segments (first segment, second segment, third segment) connected by adjusting members. This segmentation allows independent adjustment of each segment, providing flexibility in positioning the display unit to match different pupil distances without requiring complete structural redesign.
2Ease of operation
If the display unit is made adjustable for different pupil distances, then user comfort is improved, but the device structure becomes more complex
Solution Approach 1:
The adjustable rotating shaft arm unit enables the display unit to dynamically reposition according to user needs. This improves user comfort by allowing proper alignment with different pupil distances, while the modular segment-based design keeps the complexity manageable through systematic organization of adjustment components.
Solution Approach 2:
The rotating shaft arm unit serves multiple functions: it supports the display unit, enables positional adjustment for different pupil distances, and maintains structural stability. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while improving user comfort.
3Manufacturing precision
If multiple segments and adjusting members are used, then precise pupil distance adjustment is achieved, but the number of components increases
Solution Approach 1:
The rotating shaft arm unit is segmented into multiple sections (first segment, second segment, third segment) with adjusting members between them. This segmentation enables precise incremental adjustment of the display unit position, allowing accurate alignment with different pupil distances. The modular nature of these segments makes the increased component count manageable and organized.
Solution Approach 2:
The adjusting members enable dynamic repositioning of the segmented arm unit, providing precise control over the display unit's position. This dynamic adjustment capability achieves accurate pupil distance alignment while the systematic arrangement of segments and adjusting members keeps the overall component structure organized and manageable.

AI summary
A head-mounted display device is provided, which relates to a field of display device technology. The device includes: a display unit used to display a picture; a connection unit used to position the display unit in front of at least one eye of a user after the head-mounted display device is worn on a head of the user; a rotating shaft unit includes at least a first segment, a second segment, and a first adjusting member connecting the first segment and the second segment, where the first segment is connected to the connection unit, and the first adjusting member is used to change a relative position of the first segment and the second segment when the first adjusting member is subjected to an external force, so that the second segment drives the display unit to move to achieve a pupil distance adjustment.
