Modular Goggle Coupling Mechanism for Rapid Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-part spectacles are difficult to assemble and disassemble, require complex connection points that are time-consuming to secure, and often lack durability and aesthetic appeal, especially in high-mechanical-load applications like work safety goggles.
Innovation Solution
The design incorporates coupling devices on the visor, frame, and head-mounting assemblies for easy detachable connections, with holding means that ensure secure assembly and safety by preventing unintentional disassembly, featuring elongate joint projections and flexible sealing elements for comfort and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multi-piece spectacles are used, then the connection points can be made stable and solid, but the assembly becomes time-consuming and complicated
Solution Approach 1:
The spectacle is divided into separate modular components (visor assembly, frame assembly, head-mounting assembly) that can be independently manufactured and then quickly assembled together using coupling devices, reducing overall assembly time while maintaining connection stability
Solution Approach 2:
Coupling devices with holding means and counter-holding means act as intermediary elements between the different assemblies, providing stable connections without requiring complex assembly procedures - the holding means engage with the counter-holding means to secure components while allowing easy assembly and disassembly
2Strength
If complex connection points are used to ensure stability, then the connection strength increases, but the assembly and disassembly process becomes more complicated
Solution Approach 1:
The coupling devices serve as simple intermediary components that provide strong connections through their holding means and counter-holding means mechanism, eliminating the need for complex connection points while maintaining both strength and ease of operation
Solution Approach 2:
The holding means and counter-holding means are designed to automatically engage and secure the assemblies together without requiring complex assembly procedures - the design allows the components to self-align and secure through the coupling mechanism, making assembly intuitive and simple
3Ease of operation
If detachable connection systems are implemented, then the ease of assembly and disassembly improves, but the mechanical durability and reliability may be compromised
Solution Approach 1:
The coupling devices with holding means and counter-holding means serve as robust intermediary components that provide both easy assembly/disassembly and high mechanical durability - the design allows repeated attachment and detachment while maintaining connection reliability through the engineered holding mechanism
Solution Approach 2:
The connection system is designed to be dynamically adjustable - the holding means can be engaged and disengaged easily for assembly and maintenance, yet when engaged provide stable, durable connections that withstand mechanical loads during normal use

AI summary
The invention relates to goggles. The goggles comprise: a lens assembly (1) having lateral end-regions (8); a frame (2); a head-holding assembly (3); and two coupling assemblies (4) for detachably connecting same to one another. Each coupling assembly (4) comprises a first coupling device (11) arranged on the lens assembly (1), and a respective second coupling device (17) arranged on the head-holding assembly (3), said second coupling device having: a receiving means (26), that receives the head-holding assembly part, for receiving part of each first coupling device (11); and a holding body (33) that can swivel and has a holding means (37). In the assembled state of the goggles, each holding body (33) and each first coupling device (11) of each coupling assembly (4) are connected to one another in an articulated manner via at least one joint projection (36). Each coupling assembly (4) also comprises a third coupling device (18) arranged on the frame (2), which third coupling device has a frame part-receiving means (25) for receiving part of each first coupling device (11), and which third coupling device also has a counter holding means (42) assigned to each holding means (37), when the respective holding body (33) is in a holding position.
