Pivoting Key Holder with Spring Ball Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing key chain attachment devices do not effectively secure keys within a purse while allowing easy location and secure attachment to various accessories.
Innovation Solution
A pivoting apparatus with a spring and ball mechanism that retains the key holder at a specific angle, allowing easy insertion into a purse and secure attachment to other items, featuring a clasp for holding keys and an ornament for external visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the key locator is attached to a purse with a fixed structure, then the attachment is secure, but the ease of operation and quick access to keys is reduced
Solution Approach 1:
The key locator employs a pivoting member that can rotate between a first position (for easy access) and a second position (for secure attachment). The spring mechanism enables dynamic transition between these states, allowing the device to adapt its configuration based on operational needs rather than being fixed in one position.
2Adaptability or versatility
If the key locator uses a simple attachment mechanism, then the ease of operation is improved, but the adaptability to different accessories is reduced
Solution Approach 1:
The attachment mechanism is designed with a pivoting member and spring system that can accommodate various accessory types (purses, belts, attachments) through different attachment positions. The same basic mechanism adapts to different applications by adjusting the pivot angle and spring tension rather than requiring different mechanisms for each accessory type.
3Reliability
If the key holder is firmly attached to the purse, then the reliability of attachment is improved, but the ease of removing and repositioning is reduced
Solution Approach 1:
The spring mechanism is pre-loaded to automatically engage and hold the pivoting member in place, creating a self-locking effect that secures the attachment without requiring additional fastening actions. This preliminary engagement action ensures firm attachment while allowing easy release by simply overcoming the spring force.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure and easy access to keys within a purse while allowing temporary and firm attachment to different types of accessories, ensuring keys are easily located and the device remains securely attached.
Implementation Method 1
The spring and the ball may fit within the cavity of the first member. The spring and the ball may help to retain the apparatus in a first state in which the first member is at a first angle with respect to the second member.
Implementation Method 2
The spring may press against the ball and the ball may press against a portion of the first end of the second member and thereby retain the apparatus in the first state in which the first member is at the first angle with respect to the second member.
Implementation Method 3
The first end of the first member may be attached to the first end of the second member so that the first member pivots with respect to the second member.

AI summary
An apparatus is provided including a first member, a second member, a device for holding one or more keys, and an ornament. The ornament may be attached to a second end of the first member. The first member may be attached to the second member so that the first member pivots with respect to the second member. The device for holding one or more keys may be attached the second member. The apparatus may further include a spring and a ball, which help to retain the apparatus in a first state in which the first member is at a first angle with respect to the second member. The apparatus can be attached to a purse to easily locate keys.
