Eyeglass Temple Two-Component Injection Molding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglass temples are complex to produce and often fail to provide optimal adjustability, leading to suboptimal visual comfort due to their rigidity and inability to withstand high mechanical loads.
Innovation Solution
A method for producing an eyeglass temple using a two-component injection molding process, where a first material forms the main part and a second material forms the adjustment part, which are connected and pivotable, allowing for inclination adjustment between the eyeglass wearer's line of vision and the lens surface, with a pivoting and latching arrangement that enables manual or automated adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional injection molding is used to produce eyeglass temples, then production is simpler, but adjustability and visual comfort are compromised due to rigidity
Solution Approach 1:
The temple is divided into two separate injection-molded parts: a first temple part and a second temple part. These segmented parts are then connected via a hinge arrangement, allowing relative pivoting movement. This segmentation enables adjustability while keeping each individual part relatively simple to manufacture.
Solution Approach 2:
The hinge arrangement connects the two temple parts in a pivotable manner, transforming the rigid static structure into a dynamic adjustable system. The first temple part and second temple part can pivot relative to each other, providing adaptability to different wearers while maintaining simple injection molding processes for each part.
2Adaptability or versatility
If elaborate production methods are used to achieve adjustability, then visual comfort improves, but production cost and complexity increase
Solution Approach 1:
By segmenting the temple into two separately molded parts connected by a hinge, the invention achieves adjustability for visual comfort without requiring elaborate single-piece molding processes. Each part can be manufactured using standard injection molding techniques.
Solution Approach 2:
The hinge arrangement merges the two separately manufactured temple parts into a functional assembly that provides adjustability. This combining approach achieves the visual comfort benefits of elaborate designs while maintaining the production simplicity of separate, standard manufacturing processes.
3Strength
If rigid temple structures are used, then manufacturing is simpler, but mechanical load resistance and comfort are reduced
Solution Approach 1:
The pivotable hinge connection between the two temple parts creates a dynamic structure that can absorb and distribute mechanical loads more effectively than a rigid structure. The ability to pivot allows the temple to adapt to mechanical stresses while maintaining structural integrity.
Solution Approach 2:
Dividing the temple into two parts connected by a hinge distributes mechanical loads across separate components and the hinge connection itself, enhancing overall strength and load resistance without requiring a monolithic complex structure.

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 method allows for cost-effective production of user-friendly eyeglass temples with enhanced adjustability, ensuring optimal visual comfort by allowing a wide range of inclination adjustments without the need for complex assembly processes.
Implementation Method 1
A method for producing an eyeglass temple (3) is proposed, by which an eyeglass temple main part (5) and an eyeglass temple adjustment part (6) which are connected to one another in a pivotable manner are injection-molded in precisely one injection-molding tool (36)
Implementation Method 2
injecting a first material into an injection molding tool upon forming an eyeglass temple main part with a main body and an inclination bearing body; injecting a second material into an eyeglass temple adjustment part cavity of the injection molding tool upon overmolding at least partly the inclination bearing body to form an eyeglass temple adjustment part

AI summary
A method for production of an eyeglass temple, the method including an injection of a first material into an injection molding tool upon forming an eyeglass temple main part with a main body and an inclination bearing body, and an injection of a second material into an eyeglass temple adjustment part cavity of the injection molding tool upon overmolding at least partly the inclination bearing body to form an eyeglass temple adjustment part, which is penetrated by the inclination bearing body and pivotable in relation thereto, after the first material has cured at least partly, and a removal of the eyeglass temple, which is in an eyeglass temple injection molding position, from the injection molding tool when the first material and the second material have cured at least partly.
