Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid sprayers require external power sources, which can be inconvenient and pose safety hazards, especially in locations where power is not readily available.
Innovation Solution
A battery-powered fluid sprayer with an electric motor and piston pump, where the battery is mounted vertically below the sprayer body, protected from overspray by the sprayer's design, allowing for portable and cordless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If AC power is used to power the pump, then the sprayer can operate with unlimited electric power, but the sprayer requires external power sources which pose safety hazards and reduce portability
Solution Approach 1:
The patent extracts the power source from the external environment and incorporates it into the sprayer system itself by using a battery pack. This eliminates the need for external AC power sources and their associated safety hazards, while maintaining unlimited electric power operation capability.
Solution Approach 2:
The battery pack serves as an intermediary energy storage device between the environment and the electric motor. It converts chemical energy to electrical energy, providing a safe intermediate power source that eliminates direct connection to hazardous AC power sources while still delivering the required electrical power.
2Use of energy by moving object
If AC power is used to power the pump, then the sprayer can operate with unlimited electric power, but the sprayer requires power cords which reduce operational flexibility in locations where power is not readily available
Solution Approach 1:
The patent extracts the power source from external infrastructure and embeds it within the sprayer unit itself through the battery pack. This enables the sprayer to operate independently of external power infrastructure, significantly improving adaptability to various work locations.
Solution Approach 2:
The battery-powered system transforms the sprayer from a static, location-dependent device to a dynamic, mobile unit. The ability to move the power source with the device enables operational flexibility across different locations without requiring fixed power infrastructure.
3Object-affected harmful factors
If the battery is mounted vertically below the sprayer body, then the battery is protected from overspray, but the center of gravity shifts which may affect handling
Solution Approach 1:
The patent converts the potential harm of overspray contact into a protective arrangement by positioning the battery vertically below the sprayer body. The sprayer body and its components serve as a shield, using the spray trajectory itself to protect the battery from overspray contamination.
