Card Removal Tool for Tight Wallet Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional card carrying cases face difficulties in easy access, removal, and reinsertion of personal cards due to tight slots, slick surfaces, and clutter, leading to wear and tear on both the case and cards, and potential damage to cards with magnetic stripes or electronics.
Innovation Solution
A multi-purpose auxiliary member tool with a flattened, rigid U-shaped attachment component and extension component, designed to securely grip and remove personal cards from slots without bending or breaking, featuring a tapered card slot for secure friction fit and a grippable surface for easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If slots are made tight to securely hold personal cards, then card security is improved, but card removal and reinsertion becomes difficult
Solution Approach 1:
The patent introduces a card removal tool as an intermediary device that mediates between the user and the tight slot. The tool has a tapered geometry that allows it to push cards through tight slots during removal and reinsertion operations, while the card remains securely held during normal use. This intermediary tool resolves the contradiction by providing ease of operation without compromising security.
2Quantity of substance
If multiple cards are stuffed in a single tight slot, then card capacity is improved, but card removal becomes even more difficult
Solution Approach 1:
The card removal tool serves as an intermediary that can manipulate multiple cards stacked in a tight slot. The tapered shape allows the tool to push through stacks of cards, enabling removal of individual cards or multiple cards simultaneously from densely packed slots, thus maintaining high card capacity while enabling easy removal.
3Reliability
If specialized pockets are made deep for security viewing, then card security is improved, but card grasping becomes difficult
Solution Approach 1:
The card removal tool acts as an intermediary that extends the user's reach into deep specialized pockets. The tool's shaft allows it to access cards positioned completely within deep pockets for security viewing, while the extended grip surface provides leverage for easy removal without requiring direct finger access to the card edges.
4Ease of operation
If repeated removal and reinsertion of cards occurs, then card accessibility is improved, but wear and tear on cards and case increases
Solution Approach 1:
The card removal tool serves as a protective intermediary between the user's fingers and the card edges during removal and reinsertion operations. By using the tool's grip surface and tapered shaft, users can manipulate cards without directly handling their edges, thereby reducing mechanical stress, preventing damage to magnetic stripes and electronics, and minimizing wear on both cards and case slots.
