Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lotion pumps with mixed materials, such as plastic and metal components, require manual disassembly for recycling, leading to inefficiency and high costs due to the need for separate classification and processing.
Innovation Solution
A single-material all-plastic lotion pump design comprising a plastic pump casing, pressing head, cylinder casing, and double piston mechanism, allowing for direct recycling without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mixed materials (plastic and metal) are used in lotion pump components, then functional performance is improved, but recycling difficulty increases and costs increase
Solution Approach 1:
The patent applies homogeneity by replacing all metal components with plastic components, creating a uniform material composition throughout the lotion pump. The pump head, cylinder, spring, and piston are all made from plastic materials, eliminating the complexity of mixed material recycling while maintaining functional performance through careful material selection and design.
Solution Approach 2:
The patent merges previously separate material types into a single material system. By combining the functions of metal and plastic components into entirely plastic alternatives, the invention simplifies the overall material composition, making the entire pump assembly recyclable as a single material type without requiring disassembly for material separation.
2Loss of substance
If manual disassembly is performed for recycling metal springs, then material recovery is improved, but time consumption and labor costs increase
Solution Approach 1:
The patent extracts the metal spring from the system entirely and replaces it with a plastic spring. This removal of the problematic metal component eliminates the need for separate recovery processes, allowing the entire pump to be recycled through simple plastic recycling channels without time-consuming manual disassembly.
Solution Approach 2:
The patent adopts a disposable approach where the entire plastic pump assembly is designed for single-use and then recycled as a complete unit. The all-plastic construction allows the entire device to be discarded and recycled together without needing to preserve or separately recover specific components, significantly reducing recycling time and labor.
3Strength
If metal components are used in pump head, then mechanical strength is improved, but recycling cost increases
Solution Approach 1:
The patent changes the material parameter from metal to plastic for all components. By selecting appropriate plastic materials with sufficient mechanical properties and optimizing the design, the invention maintains the required mechanical strength while dramatically reducing recycling costs through uniform material composition that requires no special handling or separation processes.
