Detachable Key Holder With Tensioned Tag Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face difficulties in organizing and individually accessing multiple similar-looking keys, as they often get confused and are hard to manage when stored on a key ring, leading to potential loss and accessibility issues.
Innovation Solution
A key holder system that includes a key tag attached to each key, with a device body featuring a slot and an attachment point, where the key tag wraps around the device body to provide tension, preventing the key from sliding out, and includes a peg or hook system for secure attachment, allowing easy insertion and removal while maintaining visibility and organization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If keys are placed on a key ring, then keys are prevented from getting lost, but individually accessing each key becomes difficult
Solution Approach 1:
The key organization system is segmented into individual slots, each capable of holding one key independently. This allows users to access a single key by simply removing it from its slot without disturbing other keys, solving the accessibility problem while maintaining overall key security through the organized structure.
Solution Approach 2:
A key tag with a stretchable portion acts as an intermediary mechanism between the key and the slot. The stretchable key tag provides tension to hold the key in place within the slot, enabling secure retention while allowing easy removal when needed, thus bridging the contradiction between security and accessibility.
2Quantity of substance
If multiple similar-looking keys are stored together, then storage efficiency is improved, but key identification and selection become difficult
Solution Approach 1:
Each key is assigned to its own dedicated slot within the device body, creating visual and physical separation between similar-looking keys. This segmentation allows users to easily identify and select the correct key by its position and associated label without confusion from other keys, while still maintaining efficient storage of multiple keys in a compact organizer.
Solution Approach 2:
Each slot is equipped with a dedicated key tag featuring a label at a specific location corresponding to that slot. This local quality approach ensures that identification information is positioned directly adjacent to each key, making it easy to distinguish between similar keys while maintaining high storage capacity.
3Ease of operation
If a detachable key holder system is used, then ease of access is improved, but device complexity increases
Solution Approach 1:
The key tag incorporates a stretchable portion that dynamically adjusts its tension as the key is inserted or removed from the slot. This dynamic mechanism provides automatic retention during normal use while allowing easy removal when intentionally pulled, achieving simple operation without complex mechanical locks or fasteners.
Solution Approach 2:
The stretchable key tag changes its physical parameter (tension/extension) based on the key's position. When the key is in the slot, the tag is stretched and provides holding tension. When the key is removed, the tag returns to its relaxed state. This parameter change enables automatic key retention and easy release without complex mechanisms.
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 system effectively organizes and secures keys, preventing loss and facilitating easy access, with the key tag providing sufficient tension to keep the key in place, ensuring quick and easy insertion and removal while maintaining visibility and organization.
Implementation Method 1
the key tag includes a stretchable portion, the stretchable portion stretched onto the device body to hold the key in the slot
Implementation Method 2
the attachment point is a peg and the key tag includes an aperture for interfacing with the peg
