Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nose pads in glasses have fixed height and angle, failing to accommodate varying nose bridge dimensions, leading to sliding and focal point shifts, compromising comfort and stability.
Innovation Solution
A nose pad adjustment assembly with movable nose pad blocks and locking mechanisms, allowing adjustment to fit different nose bridge shapes, ensuring secure positioning and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the nose pad is integrally produced with fixed height and angle, then the manufacturing is simple and cost-effective, but it cannot accommodate varying nose bridge dimensions causing sliding and discomfort
Solution Approach 1:
The nose pad is divided into multiple independent adjustable components (nose pad body, connection arm, connection piece) rather than being integrally produced. This segmentation allows each component to be adjusted independently to fit different nose bridge dimensions while maintaining manufacturing simplicity through modular assembly.
Solution Approach 2:
The nose pad assembly transitions from a fixed static structure to a dynamic adjustable structure. The connection arm can rotate around the rotation axis, and the connection piece can move along the connection arm, enabling the nose pad to adapt to various nose bridge shapes and sizes while the user wears the glasses.
2Reliability
If the nose pad blocks are movable and adjustable, then the fit to individual nose shapes is improved, but the device complexity increases due to locking mechanisms
Solution Approach 1:
The adjustment mechanism is designed to be self-operating through simple user actions. The nose pad blocks can be manually moved to desired positions and locked in place using straightforward locking mechanisms that do not require complex tools or procedures, enabling users to adjust and secure the fit themselves.
Solution Approach 2:
The nose pad assembly allows adjustment of multiple parameters including the position of nose pad blocks, the angle of connection arms, and the location of connection pieces. These parameter changes enable customization to different nose bridge dimensions while maintaining reliability through corresponding locking mechanisms that secure each adjusted parameter.
3Ease of operation
If the nose pad is fixed in position, then the structure is simple and durable, but it causes sliding and focal point shifts for users with different nose bridge widths
Solution Approach 1:
The nose pad assembly is designed with pre-positioned adjustment mechanisms and locking features that allow users to make preliminary adjustments to achieve the correct fit before wearing the glasses. The connection arm and connection piece are positioned to enable easy access for adjustment while ensuring that once adjusted, the positioning is firmly locked to prevent sliding during use.

AI summary
A nose pad adjustment assembly is revealed. The nose pad adjustment assembly includes two nose pad blocks and a nose pad base which consists of a recess portion and two connection portions located at two sides of the recess portion correspondingly. The connection portion has an upper locking hole and a lower locking hole. The nose pad block includes an upper protrusion and a lower protrusion respectively movable transversely in the upper locking hole and the lower locking hole correspondingly. The upper and the lower protrusions are respectively provided with a plurality of upper and lower locking grooves which are able to be engaged and connected with the upper and the lower locking holes correspondingly. Thereby the nose pad blocks can be adjusted for close fit to user's nose bridge. Therefore, glasses are positioned without sliding freely and users feel more comfortable while wearing the glasses.
