Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bistable hinges for glasses provide a low perceived quality, bulkiness, and negative impact on aesthetics, while also being difficult to assemble and maintain.
Innovation Solution
A hinge assembly with a hinging body, elastic element, and coupling pins that allow temples to rotate between stable opening and closing positions without clearance, minimizing bulk and ensuring easy assembly and maintenance, while providing a high-value perceived quality and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional bistable hinges are used with multiple joint elements, then the temples can maintain stable opening and closing positions, but the hinge assembly creates bulkiness and negatively impacts aesthetics
Solution Approach 1:
The patent merges multiple joint elements into a single integrated hinge body that houses all necessary mechanical components (elastic element, coupling pins, joint surfaces) within one compact structure. This consolidation eliminates the need for separate distributed joint elements, reducing the overall volume and bulkiness on the temple while maintaining the bistable functionality through the integrated mechanism.
Solution Approach 2:
The hinge assembly employs a nested structure where the elastic element is housed within the hinge body, coupling pins are received within recesses of the hinge body, and multiple functional surfaces are contained within the single hinge component. This nesting arrangement allows multiple joint elements to coexist in a compact configuration, minimizing the bulk on the temple while preserving stable positioning.
2Stability of the object's composition
If traditional bistable hinges with multiple joint elements are used, then the temples can maintain stable positions, but the perceived quality and aesthetics are degraded
Solution Approach 1:
By consolidating multiple joint elements into one sleek hinge body, the patent creates a cleaner, more streamlined appearance on the temple. The integrated design eliminates the visual clutter of multiple separate components, presenting a sophisticated and minimalist aesthetic that enhances the overall appearance of the glasses while maintaining stable temple positioning.
3Stability of the object's composition
If traditional bistable hinges with multiple joint elements are used, then the temples can maintain stable positions, but the assembly and maintenance become difficult
Solution Approach 1:
The integration of multiple joint elements into a single hinge body significantly simplifies assembly, as the entire bistable mechanism can be installed as one unit rather than assembling multiple separate components. This also facilitates maintenance, as the compact integrated design allows for quicker inspection and replacement of the hinge assembly as a whole, reducing the complexity of service operations.
4Ease of operation
If joint elements are located in hinging area working in free condition, then the temples can rotate between positions, but the perceived quality is low
Solution Approach 1:
The patent integrates the free-rotating joint functionality within a single compact hinge body, eliminating the need for distributed joint elements working in free condition. This integrated approach maintains smooth temple rotation while presenting a refined, high-quality appearance by concealing the mechanical complexity within the sleek hinge structure, thereby enhancing perceived quality.

AI summary
Glasses (200) comprising a front (210) and two temples (220) rotatably coupled to the front (210) so as to rotate between a first stable opening position and a second stable closing position, the front (210) comprises two first receiving seats (211), two hinge assemblies (100) each of which comprises a hinging body (110) coupled to a respective temple (210) so that it has an end portion (111) which protrudes overhanging with respect to the temple (220) and penetrates a respective one of such first receiving seats (211) in which it is rotatably coupled to the front (210), an elastic element (130) in abutment with a bottom wall of the respective first receiving seat (211) and the end portion (111), the elastic element (130) is preloaded in compression with a preloading force, the hinging body (110) and the elastic element (130) are configured in such a way that when the respective temple (220) is in the first stable opening position or in the second stable closing position, the elastic element (130) exerts a first thrust force that is equal and opposite to the preloading force on the end portion (111), and when the respective temple (220) passes from the first stable opening position to the second stable closing position, or vice versa, said elastic element (130) is compressed with a compressive force greater than said preloading force exerted by said end portion (111).
