Container Pump Locking Pin for Adjustable Discharge Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pump systems for containers holding cosmetics and kitchen rinses face issues with inaccurate discharge control, potential contamination, and safety risks due to unsecured press buttons, which can lead to waste and accidental use by children.
Innovation Solution
A pump safety device featuring an adjusting member and safety pin mechanism that securely locks the press button when not in use, allowing for adjustable discharge control and preventing accidental activation, ensuring safe operation by allowing the press button to be pressed only when intended.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the press button is left unsecured to allow easy operation, then ease of operation is improved, but safety deteriorates due to accidental use by children
Solution Approach 1:
The safety pin is pre-installed in the locking hole of the cap, creating a preliminary safety mechanism. Before the press button can be used, the safety pin must first be removed by unscrewing the cap, which adds a preliminary safety step to prevent accidental use by children while maintaining ease of operation for intended use
2Reliability
If the press button is locked to prevent accidental use, then safety is improved, but ease of operation deteriorates due to additional locking procedures
Solution Approach 1:
The safety pin is pre-installed in the locking hole, creating a preliminary safety barrier that is automatically in place before use. This eliminates the need for users to actively engage a locking mechanism, reducing operational steps while maintaining safety
Solution Approach 2:
The safety function is extracted as a separate component (safety pin) that can be independently removed from the system. Users can take out the safety pin when intended use is required, separating the safety function from the main operation and allowing easy activation when needed
3Productivity
If the pump allows free discharge of contents, then productivity is improved, but loss of substance worsens due to inaccurate discharge control
Solution Approach 1:
The pump mechanism is pre-configured with a piston, cylinder, and spring system that automatically controls the discharge process. When the press button is activated, the piston moves within the cylinder to pump out a controlled amount of contents, then automatically returns to its initial position, providing accurate discharge control without user intervention
4Adaptability or versatility
If the container is equipped with a pump system, then functionality is improved for controlled discharge, but device complexity worsens
Solution Approach 1:
The pump components (piston, cylinder, spring, discharge tube) are merged into a single integrated assembly that fits within the cap structure. The piston is combined with the support tubular member, and the spring is integrated within the cylinder, reducing the number of separate parts while maintaining full pump functionality
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 device allows for precise control over discharge amounts, prevents contamination, and ensures safety by locking the press button to prevent accidental use, particularly by children, while allowing convenient use and adjustment of the discharge quantity.
Implementation Method 1
the piston 27 returns back by an elastic force of the spring 28 provided in the interior of the cylinder part 26
Implementation Method 2
a male screw part 31 which is formed at an outer side of a bottom of the adjusting member 30 for an engagement with the female screw part 23a of the cap 23
