Eyeglasses Temple Pad Design for Stable Wear Without Nose Pads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Eyeglasses without nose pads face a trade-off between wearing stability and appearance, as increasing the support structure size for stability makes it conspicuous, while minimizing it for appearance degrades stability.
Innovation Solution
The design incorporates temple pads with a core member made of plastically deformable metal and a synthetic resin pad body, where the core member extends along the temple and is fixed with a pocket system, providing a large contact area without being conspicuous, and is detachable for easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the size of the support structure is increased to stably support the load of the front on the wearer's temples, then the wearing stability is improved, but the support structure becomes conspicuous which impairs the appearance
Solution Approach 1:
The temple pad is inserted into a pocket formed in the temple, creating a nested structure where the support element is concealed within the temple body. This allows the temple pad to provide stable support contact with the wearer's temple while remaining hidden, thus improving wearing stability without compromising appearance.
Solution Approach 2:
The temple pad is made of a soft material that can deform elastically to conform to the wearer's temple shape. This flexibility allows the pad to maintain stable contact and support the front weight effectively, while its soft nature enables it to be inconspicuous and comfortable against the skin.
2Shape
If the support structure is made narrow and small to prioritize appearance, then the appearance is improved, but the stability is degraded when the eyeglasses are worn
Solution Approach 1:
By nesting the temple pad within the temple pocket, the design achieves a compact configuration where the full functional length of the temple pad can be utilized for stable support contact, while the overall structure remains sleek and inconspicuous from the external view.
Solution Approach 2:
The temple pad extends in the depth dimension within the pocket rather than increasing width or height, allowing it to provide sufficient contact length for stability while maintaining a narrow and aesthetically pleasing external profile.
3Ease of operation
If the temple pad is made detachable for easy replacement, then the ease of operation is improved, but the device complexity is increased
Solution Approach 1:
The temple pad is designed as a separate detachable component from the temple, allowing it to be easily removed and replaced. This segmentation enables users to replace worn or damaged temple pads without replacing the entire eyeglass frame, improving ease of maintenance while keeping the attachment mechanism simple.
Solution Approach 2:
The pocket design serves multiple functions: it conceals the temple pad for aesthetic purposes, provides a secure attachment mechanism for easy replacement, and allows for universal compatibility with different temple pad types, thereby justifying the slight increase in structural complexity through enhanced functionality.

AI summary
To be stably wearable without nose pads and to have a support structure which is inconspicuous when worn, eyeglasses (100) include: temples (30L, 30R) which are wide in an upward/downward direction; and temple pads (40L, 40R) each having a tip and a root, the root being fixed to a prescribed location on an inner side (33L, 33R) of a corresponding one of the temples (30L, 30R), each of the temple pads extending along an extension direction of the corresponding one of the temples (30L, 30R) to gradually deviates from an inner side surface of the corresponding one of the temples (30L, 30R) from the prescribed location to the tip, each of the temple pads (40L, 40R) has a root portion (41L, 41R) which is narrow and a tip portion formed to have a thick shape that gently protrudes downward, the tip portion (42L, 42R) being in contact with a wearer's temple when the eyeglasses (100) are worn, the temple pads (40L, 40R) being entirely or mostly hidden by the temples (30L, 30R) in a side view.
