Hinged Key Holder Layout for Non-Blocking Key Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing key holders with cantilevered key arrangements cause frustration by blocking the removal of smaller keys when larger keys are present, requiring unnecessary removal of multiple keys before accessing the desired one.
Innovation Solution
A key holder with segments connected by a hinge that allows movement between aligned and unaligned positions, enabling perpendicular alignment of adjacent keys for easy removal without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If keys are positioned in a cantilevered arrangement within a holder, then the keys are presented in an orderly and compact manner, but the removal of smaller keys is blocked by larger keys
Solution Approach 1:
The holder segments are made movable relative to each other through a hinge connection, allowing the arrangement to transition from a static cantilevered configuration to a dynamic configuration where segments can be separated. This enables easy removal of any key by simply moving the relevant segment, while maintaining the compact orderly arrangement when segments are connected.
2Volume of moving object
If larger keys are positioned to cantilever over smaller keys, then a compact presentation is achieved, but time is wasted removing multiple keys to access a desired key
Solution Approach 1:
The holder is divided into multiple separable segments, each capable of holding one or more keys. This segmentation allows any segment to be independently removed from the holder without affecting other segments, enabling direct access to any key in constant time without the need to remove other keys, thus eliminating the time loss while maintaining compact storage when segments are connected.

AI summary
The present invention relates to a key holder for a set of graduated keys such as hexagonal (hex) or Allen keys. The key holder includes two or more segments each having at least one opening for receiving a key. The holder further includes a hinge that is configured to permit the movement of adjacent segments between and aligned position and an unaligned position. In the aligned position, the removal of the smaller of two graduated keys is blocked when said keys are in the openings of adjacent segments and are positioned in the same direction. In the unaligned position, graduated keys in adjacent segments are perpendicular to one another and the smaller key can be removed without interference from the larger key.
