Universal Collar Key Geometry for Multi-Dispenser Container Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face the inconvenience of needing multiple containers with different keys for various dispensers, leading to a desire for a universal container that can fit and be securely held in multiple dispenser housings without the need for unique keying systems.
Innovation Solution
A universal collar key with radially extending flanges and a notch design that allows a single container to be securely inserted into multiple dispenser housings by engaging with the housing's keyplate, providing axial support and preventing movement, thus bypassing the need for specific keyways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a keying system with specific keys and keyways is used to ensure proper container-housing matching, then manufacturing precision and reliability are improved, but device complexity and the need for multiple container types increase
Solution Approach 1:
The collar key is designed with a universal geometry that can engage with multiple different keyway configurations in various housing types. The collar key includes a body with a first keyway and a second keyway at different orientations, allowing it to function with both horizontally-oriented and vertically-oriented keyways in different dispenser housings, thereby eliminating the need for multiple specialized container types
Solution Approach 2:
The collar key is designed as a separable component that can be attached to or removed from the container. This segmentation allows the universal collar key to be used with different container types while maintaining the keying function, reducing the need for integrated keying features in each container design
2Reliability
If multiple container types with different keys are provided for different dispensers, then proper fit and securement are ensured, but ease of operation and user convenience deteriorate
Solution Approach 1:
The collar key incorporates multiple keyways at different orientations (first keyway and second keyway) that can engage with various housing keyway configurations. This universal design allows a single collar key to fit and securely engage with multiple different dispenser types, simplifying container replacement for users who operate different dispensers
3Productivity
If containers are sized or contoured to fit specific housings to maximize volume utilization, then productivity and space efficiency are improved, but adaptability deteriorates
Solution Approach 1:
The collar key is designed as a separate, attachable component rather than being integral to the container body. This segmentation allows the container to maintain its optimized size and contour for volume efficiency while the detachable collar key provides the adaptability to engage with multiple housing types through its multiple keyway configurations
