Adjustable Eyewear Nosepad with Bendable Core and Releasable Bridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Eyewear with wraparound lenses, commonly used in athletic activities, often lacks an adjustable nosepad, leading to discomfort and poor fit due to non-adjustable designs.
Innovation Solution
The eyewear features a releasable nosebridge attached to the lens with a removable and adjustable nosepad, comprising a hand-bendable core member and a soft outer member, allowing for customizable fit and comfort, with the nosepad attached to the nosebridge via screws and a snap-fit mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the nosepad is made non-adjustable to simplify the structure, then the device complexity is reduced, but the adaptability to different nose sizes is worsened
Solution Approach 1:
The nosepad incorporates a core member that is hand-bendable, allowing the user to dynamically adjust the shape and size of the nosepad to match their specific nose dimensions. This dynamic adjustability resolves the contradiction by providing customization capability without requiring complex mechanical adjustment mechanisms.
Solution Approach 2:
The nosepad is divided into distinct components: a core member and an outer member that can be separated. The core member provides structural support and bendability, while the outer member provides comfort. This segmentation allows the core member to be adjusted independently to fit different nose sizes while keeping the overall structure relatively simple.
2Ease of manufacture
If the nosepad is made fixed to the lens to simplify assembly, then the ease of manufacture is improved, but the adaptability for different users is worsened
Solution Approach 1:
The nosepiece is segmented into a nosebridge and a separate nosepad that can be attached or removed from the lens. This allows the nosepad to be pre-adjusted or customized before attachment, maintaining ease of manufacture while enabling adaptability. The nosebridge itself is made releasable from the lens, further facilitating adjustment and replacement.
Solution Approach 2:
The releasable connection between the nosebridge and lens allows the nosepad configuration to be dynamically changed by removing and replacing the nosebridge with differently configured ones, providing adaptability without complicating the manufacturing process.
3Ease of operation
If the nosepad material is made soft to improve comfort, then the wearability is improved, but the structural stability is worsened
Solution Approach 1:
The nosepad uses a composite structure with a core member made of a relatively rigid material (such as metal or rigid plastic) and an outer member made of a soft, comfortable material (such as rubber or silicone). This composite construction provides both structural stability from the core member and comfort from the soft outer member, resolving the contradiction between these two requirements.
Solution Approach 2:
Different parts of the nosepad have different material properties: the core member has rigid properties for structural support, while the outer member has soft properties for comfort. This local differentiation of material quality allows the nosepad to simultaneously achieve structural stability and wearer comfort.

AI summary
Eyewear includes a lens with front and rear surfaces, a peripheral edge surface, and a recess. A nosebridge is secured to the lens and a nosepad is secured to the nosebridge. The nosebridge has first and second ends and a substantially inverted-U-shaped body. The nosepad also has first and second ends and a substantially inverted-U-shaped body. An outer member substantially encases a core member of the nosepad. The nosepad is adjustable and releasably attached to the nosebridge, which is in turn releasably attached to the lens.
