Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging tubes for paste products, such as toothpaste, are inconvenient to squeeze by hand and often result in incomplete use and waste due to manual operation limitations.
Innovation Solution
An electric pump-type packaging tube with a columnar storage cavity and a piston electric driving device, featuring various structural configurations (integral, two-segment, integral push-rod, and three-segment) that utilize a pressurization and pressure relief system to efficiently dispense the contents without manual effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual squeezing method is used, then the packaging tube structure is simple, but it is inconvenient to operate and difficult to squeeze out fully
Solution Approach 1:
The patent replaces the manual mechanical squeezing operation with an electric pump system. The electric pump includes a piston, pressurization device, and pressure relief device that work together to automatically pressurize and dispense the paste, eliminating the need for manual squeezing while maintaining simple overall structure.
Solution Approach 2:
The packaging tube is designed to be self-operating through the electric pump system. When power is supplied, the piston automatically moves to pressurize the paste and dispense it through the discharge port without requiring user intervention for the actual squeezing action.
2Loss of substance
If manual squeezing is used, then the device is simple, but the paste cannot be squeezed out fully resulting in waste
Solution Approach 1:
The electric pump system provides automated control over the paste dispensing process. The piston can be precisely controlled to move to the appropriate position to completely empty the storage cavity, ensuring no paste is left behind while maintaining relatively simple device architecture.
3Productivity
If electric pump system is added, then the dispensing control is precise, but the device complexity increases
Solution Approach 1:
The patent uses a pneumatic/hydraulic principle where the piston moves within the storage cavity to directly pressurize and dispense the paste. This fluid-based approach provides smooth, controlled dispensing action with simple mechanical components, achieving efficient productivity without excessive complexity.
4Loss of substance
If piston electric driving device is added, then the paste can be squeezed out fully, but the manufacturing complexity increases
Solution Approach 1:
The packaging tube is divided into distinct segments: the storage cavity, the piston, the pressurization device, and the discharge port. This segmentation allows each component to be manufactured separately using standard processes and then assembled, simplifying the overall manufacturing complexity while ensuring complete paste dispensing through the coordinated action of all segments.
