Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional card clips are inconvenient for inserting and retrieving cards due to their fixed structure, which limits user accessibility.
Innovation Solution
A card clip design featuring upper and lower clamping plates connected by elastic bands, allowing adjustable opening angles for easy card insertion and retrieval, with optional features like fixing shafts, protrusions, and accommodating grooves for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed structure card clip is used, then the structure is simple and stable, but it is inconvenient for inserting and retrieving cards
Solution Approach 1:
The card clip transitions from a fixed structure to a dynamic structure by introducing elastic bands that allow the clamping plates to move relative to each other. The elastic bands enable the upper and lower clamping plates to open to different angles, providing adaptability for easy card insertion and retrieval while maintaining structural simplicity through the use of flexible elastic elements rather than complex mechanical joints.
2Ease of operation
If the card clip allows large-angle opening for easy card access, then ease of operation improves, but the risk of excessive stretching increases
Solution Approach 1:
The elastic bands are pre-configured with appropriate elasticity and tension to cushion against excessive opening angles. When the user opens the clamping plates to access cards, the elastic bands stretch to provide the necessary movement freedom, but they naturally resist and stop excessive stretching through their elastic recovery force, preventing damage to the structure before it can occur.
Solution Approach 2:
The elastic properties of the bands are carefully selected to change their stiffness characteristics based on the opening angle. At normal operating angles, the elastic bands provide smooth movement for card access. When the opening angle approaches excessive limits, the elastic resistance increases nonlinearly, automatically limiting the range of motion and protecting the structure without requiring additional mechanical stops or complex control mechanisms.

AI summary
A card clip configured to accommodate card includes an upper clamping plate, a lower clamping plate, and two elastic bands. The upper clamping plate includes two first portions arranged opposite to each other. The lower clamping plate is arranged opposite to the upper clamping plate. The lower clamping plate includes two second portions arranged opposite to each other. The two second portions are respectively corresponding to the two first portions. The two elastic bands are arranged on two opposite sides of the card clip. A first end of each of the elastic bands is fixedly arranged in a corresponding first portion, and a second end of each of the elastic bands is fixedly arranged in a corresponding second portion.
