Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand pumps are limited in versatility, often clogging with thick or viscous liquids like paint, and require electrical systems for handling heavy or hard liquids, failing to efficiently deliver both fluids and gases with continuous flow.
Innovation Solution
A hand pump design featuring a chemically resistant hose, pressure cam mechanism, and integrated nozzle with duckbill valves for efficient fluid or gas delivery, combined with a fastening system for versatile use, including a roller and ergonomic handle, allowing for secure attachment and easy handling of various containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing hand pumps are used for thick or viscous liquids like paint, then they can deliver the liquid, but they clog with thick or viscous liquids
Solution Approach 1:
The pump system is divided into separable components including the pump body, hose, and nozzle assembly. The hose can be detached and cleaned separately, and the nozzle can be removed to prevent clogging in the delivery system.
Solution Approach 2:
The nozzle is designed to be removable from the hose assembly, allowing easy extraction and cleaning of the nozzle tip where clogging most commonly occurs. This enables maintenance without disassembling the entire pump system.
2Adaptability or versatility
If existing hand pumps are designed for single or dual functions, then they are simple in structure, but they lack versatility for multiple applications
Solution Approach 1:
The pump system is designed with universal components that can handle multiple functions: the pump body can deliver various liquids and gases, the hose connects to different nozzles for spraying or direct delivery, and the roller attachment enables paint application. This multi-functionality is achieved through standardized connection points rather than complex mechanical changes.
Solution Approach 2:
The system allows dynamic configuration where attachments like rollers or spray nozzles can be added or removed based on the specific task. The hose routing and nozzle positioning can be adjusted during operation to adapt to different application requirements.
3Power
If electrical systems are used to throw hard or liquid, then delivery power is sufficient, but portability and simplicity are reduced
Solution Approach 1:
The pump system is designed to be manually operated without external power sources. The user provides the mechanical input force to operate the pump mechanism, eliminating the need for electrical motors, batteries, or power connections while maintaining portability and operational simplicity.
4Reliability
If hose is not secured properly, then the structure is simple, but the connection reliability deteriorates
Solution Approach 1:
The fastening mechanism is extracted as a separate, simple component system involving clips or clamps that can be independently attached to the hose at key points. This allows the hose to be secured without redesigning the entire pump structure.
Solution Approach 2:
Reinforcement is applied locally at specific points along the hose where connections occur, rather than strengthening the entire hose uniformly. This provides enhanced connection reliability at critical locations while maintaining overall hose flexibility and simplicity.
