Collectible Card Case with Stacking Ridges and Flared Corners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protective cases for collectible cards lack features for stacking, easy card removal, and tamper-proof sealing, which are essential for long-term storage and preservation.
Innovation Solution
A protective case design featuring dual magnet clasps, ridges for stacking, a finger slot for card removal, and areas for applying a tamper-proof seal or sticker, with a magnetic engagement system and a card recess that allows non-contact corner accommodation to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional transparent flat plastic cases are used to preserve collectible cards, then the cards are protected from physical damage, but the cases lack features for stacking, easy card removal, and tamper-proof sealing
Solution Approach 1:
The case is divided into distinct functional segments: a front piece with a finger slot for card removal, a rear piece with a ledge, and stacking ridges. This segmentation allows each part to perform its specific function independently while maintaining overall protection.
Solution Approach 2:
The case incorporates a pivot mechanism that allows the front and rear pieces to rotate between open and closed positions. This dynamic feature enables easy card insertion and removal while maintaining secure protection when closed.
2Reliability
If traditional protective cases are used, then cards are preserved, but there is no structure to facilitate stacking of multiple cases
Solution Approach 1:
The stacking ridges serve multiple functions: they provide structural support for individual cases, enable stable stacking of multiple cases, and maintain the protective enclosure. This multi-functionality reduces overall system complexity.
Solution Approach 2:
The stacking ridges are self-aligning features that automatically guide cases into proper stacking positions without requiring external alignment tools or complex mechanisms.
3Reliability
If traditional cases are used, then cards are protected, but there is no feature to facilitate proper application of tamper-proof seals
Solution Approach 1:
The case includes pre-designed sealing surfaces and notches that are prepared in advance for seal application. These features guide the seal into the correct position and ensure proper adhesion without requiring additional alignment steps.
Solution Approach 2:
The sealing surfaces act as intermediaries between the case components and the tamper-proof seal. They provide a dedicated interface that ensures the seal is applied correctly and maintains the integrity of the enclosure.
4Reliability
If cards are tightly confined in traditional cases, then protection is maximized, but corner damage can occur
Solution Approach 1:
The case includes corner protection features and a flared-out cutout that create a buffer zone between the card corners and the case edges. This preemptive cushioning prevents corner damage before it can occur during handling or stacking.
Solution Approach 2:
The case provides differentiated protection at critical locations: the corner protection features and flared cutouts specifically address corner vulnerability, while the rest of the enclosure maintains tight confinement for overall protection.
5Reliability
If magnet clasps are added to secure the case, then sealing is improved, but manufacturing complexity increases
Solution Approach 1:
The magnetic sealing function is extracted as a separate feature (magnet clasp) that can be independently manufactured and then integrated into the case assembly. This reduces the manufacturing complexity of the main case body while still achieving secure sealing.

AI summary
A case for a flat collectible item. The case provides pivotably coupled front and rear pieces that move between an open condition and a closed condition encasing the collectible item in a card recess. The card recess provides flared corners to prevent damage to the encased collectible item. The front and rear pieces each have exterior surface that provide stacking ridges that are uniformly offset from their respective perimeters so that when a first case is stacked on a second case, the front stacking ridge of the first case circumscribes the second rear stacking ridge of the second case, preventing or restricting lateral shifting of the stacked cases.
