Rotating Dispensing Button Prevents Accidental Perfume Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing perfume dispensing devices with manually operated pumps risk unwanted perfume dispensing due to accidental or involuntary activation of the dispensing button.
Innovation Solution
A nebuliser device with a rotating dispensing button that has distinct angular positions, including a mounting position, a dispensing position, and a closing position, featuring engagement means to prevent axial movement when in the mounting position, allowing secure assembly and preventing involuntary dispensing during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manually operated pump with a dispensing button is used, then perfume can be dispensed through the nozzle, but the device risks unwanted perfume dispensing due to accidental or involuntary activation
Solution Approach 1:
The dispensing button is designed to rotate between different angular positions (mounting position, dispensing position, closing position) rather than simply pressing axially. This dynamic rotational movement allows the button to be locked in a closing position during transport, preventing accidental activation while maintaining ease of operation when needed.
Solution Approach 2:
The button's functional positions are segmented into distinct angular positions (mounting, dispensing, closing), each serving a specific purpose. This segmentation allows the button to be securely locked in the closing position during transport, eliminating the risk of accidental activation while preserving the dispensing function when intentionally activated.
2Ease of operation
If the dispensing button is designed for easy activation, then perfume dispensing is convenient, but the device cannot prevent involuntary dispensing during transport
Solution Approach 1:
The button transitions from a static press-only design to a dynamic rotational design with multiple angular positions. During transport, the button can be rotated to the closing position where engagement means prevent axial movement, blocking the nozzle and preventing involuntary dispensing while maintaining easy activation when rotated to the dispensing position.
Solution Approach 2:
Engagement means are introduced as an intermediary mechanism between the button and the nozzle. These engagement means prevent axial movement of the button when in the closing position, effectively mediating between the button's rotational freedom and the nozzle's need to remain blocked during transport.
3Ease of manufacture
If the button structure is simplified for manufacturing, then production cost decreases, but the button cannot be securely locked in different positions
Solution Approach 1:
Rather than creating a complex multi-component locking mechanism, the invention uses the button's own rotational dynamics combined with simple engagement means (such as cam profiles or detent mechanisms) to achieve secure positioning. This approach maintains manufacturing simplicity while ensuring reliable locking in mounting, dispensing, and closing positions.
Solution Approach 2:
The engagement means are integrated into the button structure itself rather than being separate components. This merging of the locking function into the button design simplifies manufacturing while maintaining the ability to securely lock in different angular positions through the button's rotational movement.
