Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing key management systems are cumbersome, insecure, and costly, lacking simplicity, compactness, and reliability in organizing and securing multiple keys.
Innovation Solution
A key ring with a moveable latch mechanism, electro discharge machined from titanium, featuring a first and second channel with a movable latch that secures keys by closing a gap between the ends, utilizing cantilever springs for secure engagement and disengagement, and a design that allows for easy assembly and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional spring-loaded latches or carabiner-style latches are used, then the key ring can securely hold keys, but the device becomes more complex and costly
Solution Approach 1:
The patent combines the latch mechanism and the ring body into a single integrated component. The latch is formed as an integral part of the ring, eliminating the need for separate latch components, springs, and fasteners that would be required in traditional designs. This merging reduces device complexity while maintaining security functionality through the interlocking geometry of the integrated latch and ring structure.
2Ease of manufacture
If multiple separate components are used for the latch mechanism, then the device can be manufactured using standard processes, but the manufacturing cost and assembly complexity increase
Solution Approach 1:
The latch and ring are manufactured as a single integrated component, reducing the number of parts that need to be manufactured, stored, and assembled. This integration simplifies the manufacturing process by eliminating multiple assembly steps and reducing inventory requirements for separate components.
Solution Approach 2:
The integrated latch structure serves multiple functions simultaneously: it provides the locking mechanism, forms the structural body of the ring, and creates the engagement features for keys. This multi-functionality reduces the overall component count and simplifies the device while maintaining all necessary security and operational functions.
3Volume of moving object
If a compact design is used, then the key ring is portable and easy to carry, but the latch mechanism may lack sufficient engagement strength
Solution Approach 1:
The latch features an asymmetric geometry with a curved engagement surface that complements the corresponding asymmetric feature in the ring body. This asymmetric interlocking design maximizes engagement strength within a compact form factor by distributing mechanical loads efficiently across the contact surfaces, preventing both accidental opening and excessive size.
Solution Approach 2:
The latch and ring engagement features utilize curved and spherical geometric elements that provide smooth stress distribution and strong mechanical interlocking. The curved engagement surfaces allow for gradual load transfer and maintain strength while minimizing the overall size of the engagement mechanism, achieving both compactness and durability.

Implementation Method 1
The latch can further comprise a cantilever spring for engaging the catch of the first end of the ring portion when the latch is in the closed position
Implementation Method 2
The ring portion and the latch can be wire electro discharge machining (EDM) cut from a metal, such as titanium

AI summary
A key ring comprising a ring portion having a first end and a second end where the first end includes a first channel and a catch and the second end includes a second channel and a latch disposed within the second channel of the second end. The latch is moveable between an open position such that the latch is withdrawn into the second channel exposing a gap between the first end and the second end of the ring portion and a closed position such that the latch is moved outward from the second channel to close the gap and engage the first channel and the catch of the first end of the ring portion.
