Integrated Eyeglass Temple Bearing Pin and Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glasses, particularly safety and sports glasses, lack resilience and efficient assembly methods, often requiring complex and time-consuming processes, and existing hinge connections can lead to unintentional detachment of temple pieces from the lens arrangement.
Innovation Solution
Each eyeglass temple is equipped with its own bearing pin and a locking body that allows pivoting movement while preventing unintentional detachment, replacing the need for separate bearing parts like metal or plastic rivets, and featuring a simple, automated assembly method with a latching projection that engages with the hinge attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If separate bearing components (metal or plastic rivets) are used to connect temples to lens assembly, then the connection is simple to manufacture, but the mechanical strength and resistance to unintentional detachment are insufficient
Solution Approach 1:
The patent combines the bearing pin and locking element into a single integrated component that is part of the temple structure. This merging eliminates the need for separate bearing components while providing both rotational support and anti-detachment functionality, thereby improving mechanical strength without proportionally increasing device complexity
Solution Approach 2:
The bearing pin serves multiple functions simultaneously: it acts as a rotational axis for the temple, provides structural support, and works with the locking element to prevent unintentional detachment. This multi-functionality improves mechanical strength while avoiding the need for additional separate components
2Productivity
If complex hinge connections with separate bearing parts are used, then the connection is robust, but the assembly process becomes time-consuming and difficult to automate
Solution Approach 1:
The bearing pin and locking element are pre-integrated into the temple structure during manufacturing. This preliminary action ensures that during assembly, the temple is simply mounted as a complete unit with its bearing and locking mechanism already in place, dramatically speeding up assembly while maintaining connection reliability
Solution Approach 2:
The integrated bearing pin and locking element design allows the temple to be self-contained and self-mounting. The temple brings its own bearing and locking functionality with it, eliminating the need for separate assembly steps to install these components and enabling automated assembly processes
3Reliability
If temples are designed without integrated locking elements, then the structure is simpler, but unintentional detachment of temples from lens assembly occurs
Solution Approach 1:
The locking element is designed to dynamically respond to the temple's position: it allows free pivoting movement when the temple is in normal use positions, but automatically engages to prevent detachment when the temple is in folded or extended positions. This dynamic behavior provides anti-detachment reliability without interfering with ease of pivoting during normal operation

AI summary
The invention relates to spectacles comprising a lens arrangement (1) having two lateral spectacle temple bearing arrangements (6). Each spectacle temple bearing arrangement (6) has a first hinge shoulder (7) having a first bearing opening (9) and a second hinge shoulder (8) having a second bearing opening (10) and at least one bar body insertion opening (11) formed in the first or second hinge shoulder (7, 8). The spectacles additionally comprise two spectacle temples (2), which each comprise a spectacle temple main body (15) and a bearing pin (19) connected integrally therewith, which bearing pins in the assembled state are pivotably connected to the first and second bearing openings (9, 10) of the spectacle temple bearing arrangement. Each earpiece arm (2) also has at least one bar body (22), which in the assembled state is arranged between the hinge shoulders (7, 8) of the earpiece arm bearing arrangements (6) and, in a pivoted position of each earpiece arm (2) different from an earpiece arm assembly position, holds said earpiece arms (2) and the lens arrangement (1) together in a locking manner.
