Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trigger dispensing devices face challenges in maintaining high assembly speed and reliability under harsh transportation conditions, particularly due to damage and deformation of valve components, leading to assembly stoppages and malfunctioning during suction and delivery.
Innovation Solution
A trigger dispensing head with a main valve body made from polyolefin polymer materials, featuring a shutter and flexible dispensing lip protected by an outer body wall, ensuring stable connections and seals, and incorporating recyclable components to reduce weight and enhance durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the trigger dispensing head components are made lightweight and recyclable, then the weight is reduced and environmental sustainability is improved, but the durability and resistance to damage during harsh transportation conditions deteriorate
Solution Approach 1:
The patent employs composite material construction for the main valve body, combining polyolefin polymer materials with reinforced structural elements. This allows the component to maintain reduced weight while achieving the necessary mechanical strength and damage resistance for harsh transportation conditions, resolving the contradiction between lightweight design and durability
2Productivity
If the assembly process is optimized for speed, then productivity increases, but the risk of damage to valve components during assembly increases
Solution Approach 1:
The dispensing head is designed as a segmented assembly with modular components that can be quickly connected and disconnected. The main valve body is separated into distinct functional sections with standardized connection interfaces, enabling fast assembly while protecting vulnerable valve components from damage during the assembly process
Solution Approach 2:
The patent incorporates protective features in the valve component design that provide beforehand cushioning against assembly damage. This includes reinforced mounting structures and protective positioning elements that prevent damage during high-speed assembly operations
3Manufacturing precision
If the valve components are designed for high precision, then manufacturing precision is improved, but the complexity of the device increases
Solution Approach 1:
The patent merges multiple valve functions into a single integrated main valve body component. By combining sealing, flow control, and mounting functions into one piece molded from polyolefin polymer material, the design achieves high manufacturing precision for critical valve functions while reducing overall device complexity and the number of separate precision components required
