Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional armless spectacles face issues with optical property variations due to different nose thicknesses and complex manufacturing processes, requiring multiple components and intricate mechanisms for secure fitting.
Innovation Solution
Spectacles designed as a single continuous element with flexible plastic sheets that adapt to the user's anatomy via a clip mechanism, incorporating optical properties and a spring system for secure fixation without additional supports, allowing for easy manufacturing and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional armless spectacles use multiple separate components (optics, frame, supports, bridge, spring), then the fixing system can be designed to accommodate different nose thicknesses, but the manufacturing process becomes complex and costly
Solution Approach 1:
The patent combines multiple separate components (optics, frame, supports, bridge, spring) into a single integrated piece made from one continuous sheet of material. This merging eliminates the need for complex assembly processes while maintaining the adaptability to different nose thicknesses through the flexible single-piece design.
Solution Approach 2:
The single sheet of material serves multiple functions simultaneously: it provides the optics area, the frame structure, the bridge, the supporting plates, and the spring mechanism all in one universal component, simplifying manufacturing while maintaining versatility for different anatomical features.
2Adaptability or versatility
If conventional armless spectacles use a spring mechanism to accommodate different nose thicknesses, then the spectacles can adapt to various anatomies, but the relative positions of optics change affecting optical properties
Solution Approach 1:
The patent uses a flexible single sheet that can curve and deform to accommodate different nose thicknesses while maintaining the fixed relative positions of the optics areas. The curvature of the material allows anatomical adaptation without compromising optical alignment.
3Reliability
If conventional armless spectacles use joints and springs for fixing, then the pressure for fixing can be achieved, but the manufacturing becomes more complicated and costly
Solution Approach 1:
The spring mechanism and fixing joints are merged into the single continuous sheet structure, eliminating separate components and complex assembly processes while maintaining secure fixing through the integrated elastic design.
Solution Approach 2:
The single sheet structure provides self-contained fixing functionality through its inherent elasticity and integrated design, eliminating the need for separate joints and springs that would require complex manufacturing and assembly processes.
4Ease of manufacture
If spectacles are manufactured from one single continuous piece of material, then manufacturing costs are reduced and process is simplified, but the structure must provide both flexibility for adaptation and rigidity for stability
Solution Approach 1:
The single sheet of material is designed with different local properties: areas requiring flexibility (such as the bridge and plate connections) have appropriate material characteristics, while areas requiring stability (such as the optics mounting areas) maintain geometric rigidity, all within one continuous piece.
Applied Scientific Principles
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 solution provides secure, adaptable, and cost-effective spectacles with simplified manufacturing, enhanced optical performance, and ease of use, while maintaining geometric stability and versatility across different anatomies.
Implementation Method 1
The material being used for its realisation may be operated to limit the deformation produced by the strain exercised by the plates
Implementation Method 2
the fixing force is exercised by a spring in 'C' being semi independent from the frame. This serves now as a pivot around which the mobile elements swing
