Framed Partial Glass Transaction Card for Break-Resistant Contactless Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Credit cards made of glass materials face issues with damage susceptibility and need constructions that minimize damage risk while maintaining desirable weight and appearance.
Innovation Solution
A transaction card design featuring a partial glass layer with a non-glass frame, additional layers, and a payment module, which may include booster antennas and various materials like metal, polymeric, or ceramic, to enhance durability and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If glass members are used in transaction cards to add weight and modern appearance, then the card gains desirable weight and appearance, but the card becomes more prone to damage and weaker
Solution Approach 1:
The card is divided into multiple layers including a glass member layer, a frame layer, and a core layer. The glass member is segmented into a specific shape that fits within the frame, allowing the card to have glass appearance while using other materials for structural strength.
Solution Approach 2:
The card combines multiple materials including glass, polymer, and metal in a composite structure. The glass member provides appearance and weight, while the polymer core and metal frame provide structural strength and damage resistance, creating a composite material solution that balances aesthetics and durability.
2Shape
If a full glass card is used, then the card has modern appearance and desirable weight, but the card is more susceptible to breakage and scratches
Solution Approach 1:
Different regions of the card have different material properties. The glass member provides local appearance quality where visibility and modern look are desired, while the polymer core and frame provide local strength quality in regions requiring structural integrity and damage resistance.
Solution Approach 2:
The card structure transitions from a two-dimensional surface to a three-dimensional layered construction. Multiple layers are stacked and bonded together, creating a volumetric structure that combines the aesthetic surface of glass with the structural bulk of stronger materials.

AI summary
A transaction card having a partial glass layer including an interior glass member connected to a non-glass frame. The frame defines opposite planar surfaces, has an outer periphery coextensive with the outer periphery of the card, and has a frame inner periphery spaced radially inward from the frame outer periphery. The frame inner periphery defines an interior area occupied by the glass member. The transaction card further includes at least one additional layer having a periphery coextensive with the periphery of the card, and a payment module configured for contactless operation or dual interface contact/contactless operation.
