Fluid Dispenser Cam Lug Rotary Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid product distributors face issues with the rotation of the reservoir during the connection process, which can lead to instability and an unpleasant user experience.
Innovation Solution
The distributor incorporates a cam path and a lug system with a spring mechanism, where the cam path and lug are formed by a rotary organ, allowing the lug to follow the cam path without rotating the reservoir.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cam path and lug system are used for connection, then the connection mechanism is improved, but the reservoir rotates during the connection process causing instability
Solution Approach 1:
The patent inverts the traditional cam mechanism by making the cam path fixed and the lug rotatable, or vice versa. Instead of the reservoir rotating to engage the cam path, the lug or cam path rotates independently while the reservoir remains stationary. This inversion resolves the contradiction by maintaining reliable cam-based connection while eliminating reservoir rotation and instability.
2Ease of operation
If the reservoir is made accessible for grasping, then connection/disconnection is enabled, but the aesthetics of the dispenser is compromised
Solution Approach 1:
The patent extracts the rotational connection mechanism from the reservoir body itself. By making the cam path or lug rotatable independently, the reservoir can be designed with a fully aesthetic, seamless appearance without visible grasping features. The operational interface is extracted to a separate rotating element that does not compromise the reservoir's visual design.
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
This design ensures that the reservoir remains stationary during the connection process, providing a sense of stability and quality to the user, while also masking the operation of the connection.
Implementation Method 1
a spring for urging the lug out of the cam path
