Key Organizer With Pivotable Reel For Protected Key Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional key holders, such as key rings and chains, expose keys to damage and make it difficult to find the correct key among multiple options, leading to time consumption and potential scratching of other items.
Innovation Solution
A portable key organizer with a key reel that securely stores multiple keys within a housing, using a central member and frictional restraint to maintain keys in a protected position until deployment, allowing easy pivoting for sorting and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If keys are stored on a key ring or chain in a pocket or purse, then multiple keys can be carried conveniently, but the keys are exposed to damage and can scratch other contents
Solution Approach 1:
The keys are nested within a protective housing structure. The reel containing multiple keys is inserted into a cavity within the housing, which protects the keys from external damage and prevents them from scratching other contents in the pocket or purse.
Solution Approach 2:
The key storage system is segmented into distinct functional zones: a protective housing exterior, an internal cavity for reel storage, and a deployment opening. This segmentation separates the keys from the external environment, providing protection while maintaining accessibility.
2Adaptability or versatility
If multiple keys are stored together on a key ring, then all keys are portable, but it becomes difficult to find the correct key quickly
Solution Approach 1:
The reel is designed to rotate freely within the housing cavity. When the housing is shaken or tilted, the reel rotates dynamically, causing keys to shift and present different faces. This dynamic behavior allows the correct key to be quickly identified among multiple keys without manual sorting.
Solution Approach 2:
The system uses the user's natural shaking or tilting motion to automatically rotate the reel and display the correct key. The mechanical design converts these everyday movements into key selection assistance, eliminating the need for deliberate sorting actions.
3Object-affected harmful factors
If keys are retracted within an interior cavity for protection, then keys are protected from damage, but access to keys requires additional manipulation
Solution Approach 1:
The keys are pre-positioned on the reel within the protective cavity. The reel is designed so that during normal pocket movements or when the user reaches for the housing, the reel automatically rotates to present the correct key at the deployment opening, eliminating the need for additional manipulation.
Solution Approach 2:
The reel acts as an intermediary mechanism between the protected internal cavity and the external access point. It rotates to bridge the gap between protection and accessibility, allowing keys to remain protected while enabling quick retrieval through automatic presentation at the opening.
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
The key organizer protects keys from damage, keeps them organized, and facilitates quick selection of the correct key, reducing time spent searching and minimizing risk of scratching other items.
Implementation Method 1
The frictional restraint herein employs a biasing member such as a spring, to impart a biasing force against the keys, so that they are held by friction in a substantially static positioning upon the key reel.

AI summary
A key organizer, having a housing and a reel pivotally engaged therewith, is configured for engagement of a key with said reel. The reel has a first position holding a key engaged therewith, within an internal housing of the housing. The reel is pivotable to a second position wherein a second end of a key engaged therewith is engageable with a lock to actuate it.
