Adjustable Flexible Ear-hooks for Smart Eyeglasses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smart eyeglasses have non-adjustable ear-hooks, leading to discomfort and difficulty in maintaining optimal tightness, and nose pads are cumbersome to clean and disassemble, while sound transmission by bone conduction lacks high sound quality and poses hearing risks.
Innovation Solution
The design incorporates adjustable flexible ear-hooks with memory steel wires and rubber sleeves, allowing for user-adaptive adjustment and easy cleaning of nose pads, combined with dual sound transmission modes by bone conduction and speakers, and a visual information collection system using the YOLOv5 detection model for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed non-adjustable ear-hooks are used, then manufacturing is simple, but user comfort and adaptability deteriorate
Solution Approach 1:
The ear-hook structure transitions from a fixed static design to a dynamic adjustable system. Users can bend the ear-hook to different positions along the arc-shaped positioning grooves, allowing the glasses to adapt to different head shapes and sizes, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The ear-hook is divided into multiple discrete positioning positions along an arc-shaped path, with each position corresponding to a specific tightness level. This segmentation allows for precise adjustment while maintaining structural simplicity through the use of positioning grooves and beads.
2Adaptability or versatility
If elastic ear-hooks are used for adjustment, then adaptability improves, but the ear-hooks rebound after adjustment causing instability
Solution Approach 1:
The positioning bead structure provides mechanical feedback by engaging with specific positioning grooves at predetermined locations. When the user bends the ear-hook, the bead snaps into one of the arc-shaped grooves, providing tactile confirmation and maintaining the adjusted position without rebound, thus ensuring stability.
Solution Approach 2:
The positioning bead acts as an intermediary between the flexible ear-hook material and the fixed positioning grooves. This intermediary mechanism allows the ear-hook to be flexible during adjustment while maintaining stability when positioned, resolving the contradiction between adaptability and stability.
3Ease of operation
If nose pads are connected by screws and connecting rods, then structural strength is maintained, but ease of operation for cleaning deteriorates
Solution Approach 1:
The complex screw and connecting rod mechanism is extracted and replaced with a simplified integrated design. The nose pads are directly connected to the bridge through a streamlined structure that eliminates multiple fastening components, making the assembly easy to remove and clean while maintaining sufficient structural strength.
Solution Approach 2:
The simplified nose pad connection structure serves multiple functions: it provides structural support, allows easy removal for cleaning, and maintains comfort. This multi-functional design resolves the contradiction between ease of operation and structural strength.
4Object-affected harmful factors
If bone conduction transmission mode is used, then hearing safety is improved, but sound quality deteriorates
Solution Approach 1:
The patent combines both bone conduction and traditional speaker-based air conduction transmission modes into a single eyewear device. Users can switch between the two modes depending on their needs, allowing the device to provide hearing protection through bone conduction when needed while maintaining high sound quality through speakers when hearing safety is not a concern, thus resolving the contradiction between hearing safety and sound quality.
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 solution provides comfortable, adjustable eyewear with improved sound quality and safety features, reducing hearing risks and enhancing user experience through adaptable ear-hook tightness and advanced visual information collection capabilities.
Implementation Method 1
flexible ear-hooks include memory steel wires and rubber sleeves therein... the memory steel wire can be bent in any state through use of an elastic material and will not rebound
Implementation Method 2
They may adopt transmission modes by bone conduction and by speakers. According to the transmission mode by bone conduction, small bones (auditory ossicles) of the inner ears are vibrated through pressure waves, and these vibrations are converted into tiny electronic brain waves
