The adjustable temple design of sunglasses mainly enhances the wearing experience from three dimensions: material, structure and function. The following is a specific analysis:
First, the regulation mechanism and implementation method
Material selection
Elastic material: High-elastic metals (such as titanium alloy) or memory plastics are used to endow the temple with flexibility and resilience, adapting to different head measurements.
Anti-slip material: The ends of the temple are wrapped with rubber or silicone to increase friction and prevent slipping during movement.
Lightweight design: Utilizing ultra-light materials such as titanium wire (like 0.18mm titanium wire woven), it reduces the wearing burden and enhances comfort.
Adjustment dimension
Length adjustment: Through the telescopic structure or segmented design, users can adjust the length of the temple according to the head circumference to ensure a good fit.
Angle adjustment: Some of the temple legs support 360-degree rotation or bending, adapting to different face shapes and wearing habits.
Elastic adaptive: By using memory titanium alloy or elastic hinges, the temples automatically fit the contour of the head when worn, eliminating the need for manual adjustment.
Operation mode
Manual adjustment: Length or Angle adjustment can be achieved by sliding, rotating or pressing, and the operation is simple and intuitive.
Stepless adjustment: By using elastic materials or magnetic attraction structures, stepless adjustment is achieved, enhancing convenience.
Second, application scenarios and advantages
Sports scene
Anti-slip and stability: The lens legs wrapped in anti-slip rubber remain stable even when sweating or engaging in vigorous exercise, preventing the lenses from shifting.
Impact resistance: The elastic material can buffer external force impacts, protecting the safety of the lenses and the face.
Quick mode switching: Some temples are equipped with a built-in rotation system, allowing for a 1-second switch between daily and exercise modes to meet the needs of different scenarios.
Wear for a long time
Pressure distribution: The elastic temple and anti-slip material can reduce the pressure on the head and ears, avoiding discomfort after long-term wearing.
Breathability: The open temple design or hollowed-out structure can promote air circulation and reduce the feeling of stuffiness.
Special face shape fit
Wide and narrow head circumference adaptation: The length adjustment function can adapt to different head circumferences, preventing the temple of the glasses from being too tight or too loose.
High and low ear position adaptation: The Angle adjustment function ensures that the temple of the glasses fits the ears tightly, enhancing the wearing stability.
Third, design challenges and solutions
The balance between stability and lightweight
High-strength materials: High-strength lightweight materials such as titanium alloy are adopted to ensure that the temple is both lightweight and durable.
Structural optimization: Reduce weight through hollowed-out design or hollow frame while maintaining support.
Adjust the durability of the structure
Precision components: High-precision mechanical structures or elastic materials are adopted to reduce wear caused by frequent adjustments.
Mechanical wear-free design: such as magnetic attraction adjustment or elastic adaptive design, to avoid long-term wear and tear of mechanical components.
Cleaning and Maintenance
Detachable design: The anti-slip sleeve at the end of the temple is detachable and washable to prevent dirt from remaining.
Corrosion-resistant materials: Use corrosion-resistant materials (such as titanium alloy) to extend service life.
Fourth, user feedback and improvement directions
Q&A
Some users have reported that the adjustment range is insufficient and cannot be adapted to extreme head circumferences or face shapes.
The complexity of the adjustment structure may increase the operational difficulty, especially for elderly users.
Improvement direction
Personalized customization: By integrating 3D scanning technology, the shape and length of the temple are customized based on the user’s head data.
Intelligent adjustment system: By detecting the wearing status through sensors, it automatically adjusts the Angle and length of the temple.
Modular design: It offers replaceable temple modules, allowing users to select temple modules of different materials or functions according to their needs.
