Height-Adjustable Nose Pad Frame for Glasses-Type Wearables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display devices with thin and light glasses-type designs face challenges in providing a satisfactory viewing experience due to varying nose bridge heights among users, as the nose pad frame cannot be adjusted to align properly with each user's eyes.
Innovation Solution
A wearable device with a height-adjustable nose pad frame and a movable fixing element that allows continuous adjustment and fixation, enabling the nose pad frame to be positioned optimally for different users, regardless of their nose bridge height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the nose pad frame height is fixed, then the device structure is simple, but it cannot accommodate different nose bridge heights
Solution Approach 1:
The nose pad frame is designed to be movable along the bridge rather than fixed, allowing dynamic adjustment of height to accommodate different nose bridge heights. The fixing element can lock the frame at various positions, providing adaptability while maintaining a relatively simple structure.
Solution Approach 2:
The height parameter of the nose pad frame is made adjustable, allowing it to change position vertically along the bridge. This parameter change enables the device to adapt to different users' nose bridge heights without requiring multiple different frame designs.
2Ease of operation
If the nose pad frame is made adjustable, then viewing alignment improves, but the structure becomes more complex
Solution Approach 1:
The nose pad frame is designed to be movable along the bridge rather than fixed, allowing dynamic adjustment of height to accommodate different nose bridge heights. The fixing element can lock the frame at various positions, providing adaptability while maintaining a relatively simple structure.
Solution Approach 2:
The elastic element automatically pushes the nose pad frame to a position that contacts the user's nose, providing self-adjustment functionality. This reduces the need for complex manual adjustment mechanisms while still achieving proper viewing alignment.
3Stability of the object's composition
If a fixing element is added to lock the nose pad frame, then positioning stability improves, but device complexity increases
Solution Approach 1:
The elastic element automatically pushes the nose pad frame to a position that contacts the user's nose, providing self-adjustment functionality. This reduces the need for complex manual adjustment mechanisms while still achieving proper viewing alignment.
Solution Approach 2:
The fixing element allows the nose pad frame to be locked at different height positions along the bridge. This simple parameter change mechanism provides stable positioning without requiring complex locking systems, as the element can be moved to engage at various points along the bridge.

AI summary
A wearable device includes a body, a nose pad frame, a first elastic element and a fixing element. The body has a bridge. The nose pad frame is movably arranged at the bridge. The first elastic element is arranged between the bridge and the nose pad frame. The fixing element is movably arranged at the bridge for fixing the nose pad frame or allowing the nose pad frame to move steplessly.
