Eyeglass Screw Connection Angled for Temple Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglasses face challenges in the complex glazing process, where there is a risk of damaging the frame and temples when screwing together the frame sections, and the process requires removal of the temples, which can lead to scratches.
Innovation Solution
The eyeglasses feature a screw connection on the frame at the transition region to the temple, arranged at an acute angle of at least 8° relative to the temple extension, allowing for simplified access with a screwing tool without needing to remove the temples.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screw connection is arranged perpendicular to the temple extension for easy access, then the screwing operation becomes simpler, but the risk of damaging the temple and frame increases
Solution Approach 1:
The screw connection is deliberately positioned at an acute angle (8-45 degrees) relative to the temple extension rather than perpendicular to it. This asymmetric angular arrangement allows the screwing tool to access the connection from a direction that avoids direct contact with the temple and frame, thereby reducing damage risk while maintaining operational feasibility
2Ease of operation
If the temple is removed from the frame to access the screw connection, then the screwing operation becomes accessible, but the complexity of the glazing process increases and damage risk increases
Solution Approach 1:
The screw connection is pre-positioned at an acute angle to the temple extension during frame assembly, so that when the temple is subsequently attached, the screw connection remains accessible from the outside. This preliminary angular arrangement eliminates the need for temple removal and simplifies the overall glazing process while maintaining access for screwing operations
3Device complexity
If the screw connection is positioned for easy access without temple removal, then the glazing process is simplified, but the risk of scratches and damage to the frame and temple increases
Solution Approach 1:
The acute angular positioning of the screw connection acts as an intermediary geometric arrangement that mediates between the need for accessibility and the need to protect the temple and frame. This angular intermediary design allows the screwing tool to reach the connection point without requiring temple removal or causing direct contact that would lead to scratches and damage

AI summary
A pair of eyeglasses is provided with an eyeglass frame, from which a left and a right eyeglass lens of the eyeglasses is held, and with two eyeglass temples connected to the eyeglass frame, wherein the left lens is arranged between an upper frame element and a lower left frame element of the eyeglass frame and the right lens is arranged between the upper eyeglass frame section and a lower right frame element of the eyeglass frame. In a left temple fastening region, the upper frame element and the lower left frame element extend along a common left extension direction and can are releasably fastened to one another by means of a left screw connection, which extends along a left connecting direction. In a right frame fastening region, the upper frame element and the lower right frame element extend along a common right extension direction and can be releasably fastened or are releasably fastened to one another by means of a right screw connection, which extends along a right connecting direction. The left connecting direction and the left extension direction form a left acute angle (α-l) of at least 8° in a top view onto the eyeglasses from the top. Alternatively or additionally, the right connecting direction and the right extension direction form a (right) acute angle (α-r) of at least 8°.
