Wearable Display Mounting Adaptability via Universal Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display devices worn on the face can be difficult to stabilize due to their weight and lack of adaptable mounting options, as they often require a specific holder that may not fit all users comfortably.
Innovation Solution
An image display system with a frame that includes a joint portion for mounting either a first attachment, such as a semicircular headband, or a second attachment, like headwear, allowing users to select the most suitable mounting method and adjust the position for stable wear, along with a cover for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image display device is fixed to a specific holder (e.g., semicircular headband or looped headband), then the device can be held on the user's face, but the device cannot be adapted to different user head shapes and mounting preferences
Solution Approach 1:
The frame is designed with a universal joint portion that can accommodate multiple types of attachments (semicircular headband, looped headband, or other custom attachments) through a standardized mounting interface. This allows a single frame design to serve multiple mounting purposes and adapt to different user preferences and head shapes without requiring multiple specialized frame designs.
2Reliability
If the image display device is made heavier to provide better support and stability, then the device can be held more securely on the user's face, but the device becomes more difficult to wear and hold stably due to its weight
Solution Approach 1:
The mounting system is segmented into separate functional components: the frame with joint portion, the attachment mechanism, and the display unit. This segmentation allows the weight to be distributed across different parts that can be independently optimized. The frame provides structural support while the attachment mechanism provides securing force, allowing each component to be minimized in weight while maintaining overall stability.
3Adaptability or versatility
If the image display device uses a fixed mounting structure, then the device structure is simpler, but the device cannot be adjusted for different users and head shapes
Solution Approach 1:
The frame incorporates a universal joint portion with standardized mounting interfaces that can accept various attachment types. This universal design allows the same frame structure to be manufactured once and then adapted to different users through interchangeable attachments, rather than requiring customized frames for each user or attachment type.
Solution Approach 2:
The mounting system transitions from a fixed, static structure to a dynamic, adjustable system where the joint portion can accommodate different attachment configurations. This dynamic capability allows the mounting system to adapt to different users and preferences while maintaining a consistent base frame design for manufacturing efficiency.

AI summary
An image display system may include an image display device, and first and second attachments. The image display device may include a frame wearable on a user's face, a display unit, display controlling unit causing the display unit to display an image, and a joint portion provided on the frame, capable of having the first attachment mounted thereon, capable of having the second attachment mounted thereon, and capable of selectively having one of the first and second attachments mounted thereon when the image display device is used. The first attachment may include an engaging portion capable of engaging with a use's head and a first attaching portion that attaches the engaging portion to the joint portion. The second attachment may include a fixing portion fixable to headwear covering the user's head and a second attaching portion that attaches the fixing portion to the joint portion.
