Inflatable Cushion Glasses for Secure Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional glasses are uncomfortable due to hard plastic or metal temple pieces that do not fit the user's ears well, leading to frequent falling and discomfort, and nose cushions that shift and cause focusing issues.
Innovation Solution
A pair of glasses with inflatable buffer and supporting cushions that can be adjusted using an air pump system to fit the user's ears and nose, ensuring secure and comfortable wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If hard plastic or metal temple pieces are used, then structural strength is improved, but wearing comfort deteriorates
Solution Approach 1:
The patent applies flexible silicone material to create temple pieces that can deform and adapt to the user's ear shape. The silicone temple pieces replace rigid plastic or metal structures, providing both structural integrity and comfort through material flexibility and conformability to anatomical surfaces.
2Ease of manufacture
If fixed-size cushions are used, then manufacturing simplicity is improved, but adaptability deteriorates
Solution Approach 1:
The patent implements inflatable cushions that can change their volume and shape dynamically. The cushions are connected to an air pump system that allows users to adjust the cushion size in real-time, enabling a single fixed-structure product to adapt to different user anatomies and preferences while maintaining manufacturing simplicity.
3Reliability
If silicone hooks are added to prevent falling, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent combines the temple piece and cushion into an integrated structure. The silicone temple pieces directly incorporate cushion elements, eliminating the need for separate silicone hooks. This integration maintains the anti-falling function while simplifying the putting on and taking off process, as users only need to manipulate the temple pieces themselves rather than attaching additional components.
4Adaptability or versatility
If cushions are made slightly shiftable, then adaptability is improved, but stability deteriorates
Solution Approach 1:
The patent implements an inflatable cushion system with an air pump that allows users to adjust cushion firmness and position. The feedback mechanism enables users to find the optimal balance between adaptability and stability by adjusting the air pressure, ensuring the glasses remain securely positioned on the nose while accommodating individual anatomical variations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The inflatable cushion system provides a secure and comfortable fit, preventing glasses from falling and allowing for precise adjustment of the focusing position, enhancing both safety and usability.
Implementation Method 1
When the air pump is enabled, an ambient gas is transferred to the two supporting cushions and the two buffer cushions through the air channel. The two supporting cushions and the two buffer cushions are inflated with the gas and expanded.

AI summary
A pair of glasses with a wearing cushion device comprises a main body, an inflatable cushion system, an air pump, a switch element, a control unit and an air channel. The inflatable cushion system comprises two supporting cushions and two buffer cushions. When the switch element is turned on, the switch element issues an enabling signal to the control unit and the control unit enables the air pump in response to the enabling signal. When the air pump is enabled, an ambient gas is transferred to the two supporting cushions and the two buffer cushions through the air channel. The two supporting cushions and the two buffer cushions are inflated with the gas and expanded, so as to fit closely on the ears of the user by the two buffer cushions, and fit closely on the bridge of the nose of the user by the supporting cushions.
