Resin-Embedded Display Card for Floating Precious Metal Ingot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cards that incorporate small precious metal ingots or valuable coins fail to display the object effectively, as the thick frames and transparent plastic sheets cause visual deformation, air trapping, and limited longevity due to non-compactness.
Innovation Solution
A card design with a through aperture larger than the object, embedded in transparent resin to fill the surrounding space, and covered by two transparent films, allowing the object to appear as if floating and enhancing visibility from all sides while maintaining a compact and durable structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a thick frame is used to hold the ingot in a central position, then the ingot remains stable in the aperture, but the frame causes visual deformation and prevents the side surface of the ingot from being properly seen
Solution Approach 1:
The patent removes the thick frame structure that was previously used to hold the ingot in position. Instead, the ingot is held by adhesive applied to the inner surface of the aperture, eliminating the visual obstruction caused by the frame while maintaining the ingot's stable positioning and full visibility from all sides.
2Stability of the object's composition
If two transparent plastic sheets are laminated on both surfaces to confine the ingot, then the ingot is secured in position, but air is trapped between the sheets causing the card to be non-compact and reducing longevity
Solution Approach 1:
The patent eliminates the dual transparent plastic sheet lamination structure that trapped air between layers. Instead, a single transparent plastic sheet is used, with the ingot adhered directly to its inner surface facing the aperture. This removes the air-trapping multi-layer structure while maintaining secure positioning of the ingot and achieving a compact, durable card construction.
3Illumination intensity
If a through aperture larger than the ingot is used, then the ingot can be displayed from all sides, but a transparent peripheral area is created that allows air to be trapped and the structure to be deformed
Solution Approach 1:
The patent introduces adhesive as an intermediary substance applied to the inner surface of the aperture to hold the ingot in position. This allows the use of a larger through aperture for full visibility while the adhesive prevents air trapping and structural deformation in the transparent peripheral area, maintaining both visibility and structural integrity.

AI summary
The card forming a support for a valuable object, particularly a small precious metal ingot incorporated in said card, includes a core with a through aperture in which said valuable object is arranged, said through aperture having larger dimensions than those defined by the contour of said valuable object in the main geometric plane of said card. This valuable object is located in a central area of the through aperture so that a transparent peripheral area surrounds the valuable object inside said through aperture. The valuable object is embedded in a transparent resin which entirely fills the area peripheral to said valuable object between said object and the contour of the through aperture, so that the space remaining in the aperture around the valuable object is entirely filled by the resin.
