Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card packages fail to effectively prevent cards from dropping out during use due to inadequate fastening mechanisms, leading to a suboptimal user experience.
Innovation Solution
A push-pull anti-dropping card package design featuring a movable fastening block and anti-slip block mechanism that securely clamps and limits card movement, using elastic pressing blocks and fastening strips to prevent cards from falling out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single elastic piece is used for card fastening, then the device complexity is reduced, but the card can still be thrown out during carrying
Solution Approach 1:
The patent divides the fastening function into multiple independent components: a first elastic piece and a second elastic piece, each providing fastening force from opposite sides. This segmentation allows the system to achieve better reliability without excessive complexity, as each elastic piece is a simple, independent element that works in conjunction with the other to securely hold the card.
Solution Approach 2:
The patent applies different fastening mechanisms at different locations: the first elastic piece provides fastening at one end of the card, while the second elastic piece provides fastening at the other end. This local differentiation ensures that the card is securely held at multiple points, preventing it from being thrown out during carrying while maintaining overall structural simplicity.
2Ease of operation
If a pushing device is added to enable easy card retrieval, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent merges the pushing function with the existing fastening structure by using the same elastic pieces and blocking components to both secure and release the card. The blocking piece, when moved, simultaneously releases the fastening action and pushes the card outward, combining two functions into a unified mechanism that improves ease of operation without adding significant complexity.
Solution Approach 2:
The elastic pieces serve multiple functions: they act as fastening elements to hold the card securely, and they also serve as pushing elements to eject the card when the blocking piece is moved. This multi-functionality reduces the need for separate components, maintaining device simplicity while enabling easy card retrieval.
