Modular Eyegear Frame with Lockable Tab Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyegear assembly structures are complex and time-consuming, making them inconvenient to assemble.
Innovation Solution
The eyegear features a simple structure with a frame seat unit, bridge, and lens units, where each frame seat and lens unit are connected via a releasably lockable tab and engaging slot, allowing for easy assembly and disassembly by inserting a tab into a slot and using a resilient piece to secure the lens unit in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional eyegear assembly structures are used, then frame parts can be replaced, but the assembly structure becomes complicated and time-consuming
Solution Approach 1:
The eyegear is divided into modular components: frame seats, lens units, and temple units that can be independently assembled and disassembled. Each lens unit can be separately installed into the frame seats, allowing easy replacement without affecting other parts of the eyegear structure.
Solution Approach 2:
A bridge structure serves as an intermediary component that connects the two frame seats and provides a mounting interface for the lens units. The bridge simplifies the assembly by providing a centralized structure that facilitates the installation and removal of lens units without requiring complex fastening mechanisms.
2Adaptability or versatility
If conventional eyegear assembly structures are used, then frame parts can be replaced, but assembly becomes inconvenient and time consuming
Solution Approach 1:
The eyegear is divided into modular components: frame seats, lens units, and temple units that can be independently assembled and disassembled. Each lens unit can be separately installed into the frame seats, allowing easy replacement without affecting other parts of the eyegear structure.
Solution Approach 2:
The lens units are designed with self-retaining features that allow them to be easily installed and secured into the frame seats without requiring additional tools or complex fastening operations. The modular design enables users to perform assembly and disassembly operations themselves quickly and easily.
3Ease of operation
If simple assembly structure is provided, then assembly is easy and quick, but secure joining of lens unit and frame seat may be compromised
Solution Approach 1:
The frame seat and lens unit are designed with complementary engagement features that merge together to form a secure connection. The frame seat includes a recess with retaining walls that receive and hold the lens unit, combining structural support with secure retention in a single integrated design.
Solution Approach 2:
The engagement interface between the frame seat and lens unit incorporates curved or rounded features that facilitate easy insertion while maintaining secure holding. The rounded corners and curved surfaces of the recess and lens unit edges allow for smooth assembly motion while the geometry ensures positive retention.

AI summary
A frame seat unit of an eyegear includes a pair of frame seats and a bridge interconnecting the frame seats. Each of the frame seats defines an accommodation space that opens downwardly and has a frame strip that defines a top side of the accommodation space. The eyegear further includes a pair of lens units, each removably retained in the accommodation space of a respective one of the frame seats and including a lens frame and a lens. The lens frame has a ring portion for holding the lens therein. For each pair of the frame seat and the respective one of the lens units, one of the frame strip and the lens frame includes a releasably lockable tab, and an other one of the frame strip and the lens frame is formed with an engaging slot for engagement with the releasably lockable tab.
