Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spectacle cases do not effectively protect glasses and lenses from mechanical and mild shocks, abrasion, and are not designed for reduced size and increased flexibility, making them inconvenient for carrying.
Innovation Solution
A flexible spectacle case with a material body made of natural or synthetic leather, paper, textile, or plastic, featuring a rectangular design with rounded corners, a central trapezoidal recess, and a helical spring clamp for secure attachment and protection, allowing for adjustable sizing and easy carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid spectacle case is used, then protection against mechanical shocks is improved, but weight and flexibility worsen
Solution Approach 1:
The patent applies beforehand cushioning by incorporating a foam insert within the spectacle case that is pre-formed to cushion and absorb mechanical shocks before they reach the glasses. This foam layer acts as a protective barrier that mitigates impact forces during transport or storage, resolving the contradiction by providing shock protection without requiring the entire case to be rigid and heavy.
2Reliability
If a rigid spectacle case is used, then protection against abrasion is improved, but flexibility and reduced size worsen
Solution Approach 1:
The patent employs flexible shells and thin films by using a flexible outer case material combined with a foam insert that can be compressed and adapted to different case sizes. This flexible construction allows the case to be reduced in size for portability while still providing abrasion protection through the foam layer's dense cellular structure that resists surface damage.
Solution Approach 2:
The patent applies composite materials by combining different materials with complementary properties: a flexible outer shell material for adaptability and size reduction, and a foam insert material for abrasion protection. This composite structure resolves the contradiction by allowing each material to perform its specialized function - the flexible shell provides adaptability while the foam provides abrasion resistance.
3Stability of the object's composition
If a traditional spectacle case design is used, then structural stability is improved, but device complexity and manufacturing cost worsen
Solution Approach 1:
The patent applies segmentation by dividing the spectacle case into distinct functional segments: an outer shell structure for structural stability and a separate foam insert for protection. This segmentation allows each component to be manufactured independently using simple processes, reducing overall device complexity and manufacturing cost while maintaining structural stability through the shell and protective functionality through the foam insert.
