Volatile Dispenser Button with Cam Guide for Activation Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing volatile composition dispensers lack a clear indication of activation, leading to user confusion and potential tampering issues, resulting in reduced consumer satisfaction and defective products being sold.
Innovation Solution
A volatile composition dispenser with a housing, rupturable cartridge, and a push button mechanism that includes a cam guide and protrusion, allowing axial and rotational movement, providing a visible signal of activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a push button actuator is used to rupture the cartridge, then the activation function is achieved, but there is no visible indication of activation
Solution Approach 1:
The button changes its visual appearance (color or position) to indicate activation status. When the button is pressed and rotated, it moves to a different position or changes color, providing a clear visual signal to the user that the cartridge has been ruptured and the air freshener is activated.
Solution Approach 2:
The button mechanism provides immediate feedback to the user through tactile and visual means. The rotation movement and position change of the button give real-time feedback about the activation state, eliminating uncertainty about whether the cartridge has been properly ruptured.
2Loss of information
If the button only moves axially, then the structure is simple, but there is no visible signal of activation
Solution Approach 1:
The button movement is extended from one dimension (axial) to two dimensions by incorporating rotational movement. This additional rotational dimension provides a visible indication of activation while maintaining a straightforward operating motion that users can easily perform.
3Reliability
If no indication mechanism is added, then the device complexity remains low, but users cannot detect tampering or activation
Solution Approach 1:
The button's visual appearance changes to indicate tampering or activation. This simple visual change mechanism provides reliable detection capability without adding complex sensors, electronics, or multiple moving parts.
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 dispenser offers a clear tactile and visual indication of activation, ensuring user satisfaction and preventing tampering detection, thereby reducing defective products.
Implementation Method 1
a cam guide disposed on the inner wall or the button body; wherein the cam guide is a helical guide rail on the inner wall or the button body; and a protrusion disposed on the other of the inner wall or the button body wherein the protrusion is engaged with the cam guide in response to the axial movement of the push button
