Detachable Spectacle Frame With Kink Hinge And Clip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spectacle frames are rigid and require professional assembly/disassembly, limiting user customization and increasing costs due to the need for multiple frames for different lens sets, and suffer from loose screws in the temple-front connection, leading to incorrect positioning and potential loss.
Innovation Solution
A detachable frame design featuring press-fit mechanical means with a laminar projection and angled kink geometry for hinged connection between the front and temples, allowing user-manipulated assembly and disassembly without screws, along with a clip for securing lenses and enabling customizable designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional welded or screwed joints are used to connect front and temples, then structural strength is improved, but ease of operation deteriorates (requiring professional assembly/disassembly)
Solution Approach 1:
The connection system is segmented into a laminar projection on the front and a separate kink structure on the temple hinge, allowing independent manipulation of each component for assembly and disassembly while maintaining structural integrity through their interlocking geometry
Solution Approach 2:
The connection transitions from a static welded joint to a dynamic press-fit mechanism where the kink can be elastically deformed during assembly/disassembly and then returns to its original shape to maintain a secure connection, enabling user-operated changes in connection state
2Ease of operation
If screws are used for temple-front connection, then ease of operation is improved, but reliability deteriorates (screws easily loosened and lost)
Solution Approach 1:
The kink structure acts as an intermediary between the temple and front, providing a screwless connection mechanism where the elastic deformation of the kink material creates and maintains the connection without requiring separate fastening elements that can loosen or be lost
Solution Approach 2:
The kink structure performs multiple functions automatically: it provides the connection interface, maintains connection stability through its elastic memory, and enables user-operated assembly/disassembly without requiring additional fastening or locking mechanisms
3Manufacturing precision
If permanent mounting of lenses is used, then manufacturing precision is improved, but adaptability deteriorates (cannot easily change lenses or frames)
Solution Approach 1:
The frame is segmented into independently replaceable components (front, temples, clips), allowing users to interchange lenses by removing and reattaching fronts or temples without affecting the integrity of other components, while each component maintains precise manufacturing features for reliable reassembly

AI summary
Detachable spectacle frame formed by a front, which in turn includes some rims, a bridge, some lugs and some nose pads; a pair of temples; in which each of the temples includes a hinge to engage the front, and a terminal end, where each of the rims and their corresponding temples has a defined slot. The removable frame being characterized in that each of the lugs further includes a laminar projection, finished by a hook; the hinge of each of the temples incorporates a recess and a kink and; further incorporates a fastening clip engaging the lug.
