Spray Gun Control Module for Battery Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray guns lack the ability to efficiently manage battery power usage, leading to potential battery drain during cleaning tasks and inefficient operation.
Innovation Solution
A spray gun with a control module that displays battery power and fluid driving element state in real time, allowing users to adjust power settings based on need, and a detachable design for the display screen to prevent damage during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the spray gun operates at high power continuously, then cleaning efficiency is improved, but battery life is reduced
Solution Approach 1:
The spray gun implements dynamic power adjustment through a speed regulation switch that allows users to change operating power levels during use. The system transitions from static high-power operation to dynamic power management, enabling users to switch between high power (for stubborn stains) and low power (for routine cleaning) based on real-time needs, thereby extending battery life while maintaining cleaning efficiency when required
Solution Approach 2:
The patent applies parameter changes by modifying the power consumption parameter of the fluid driving element based on cleaning requirements. The control module adjusts operating parameters (power level, speed) according to battery status and cleaning needs, transforming the fixed-parameter operation into variable-parameter operation that optimizes both productivity and energy conservation
2Stability of the object's composition
If the display screen is fixedly installed on the gun body, then structural integrity is improved, but damage risk during assembly/disassembly increases
Solution Approach 1:
The display screen is segmented from the main gun body structure through a detachable mounting design. Instead of being permanently fixed, the display screen can be independently removed and reinstalled, separating it from the primary structural assembly. This segmentation allows the display screen to be protected during assembly and disassembly operations while maintaining structural integrity when installed
Solution Approach 2:
The detachable display screen design provides beforehand protection by allowing the display screen to be removed before assembly operations that might cause damage. Users can install or remove the display screen at appropriate stages during assembly/disassembly processes, preventing potential damage before it occurs while maintaining structural integrity during normal operation
Data Source
AI summary
A spray gun includes a gun body, a flow passage, a fluid driving element, a control module, a switch assembly and a battery pack. The control module is configured to obtain power information of the battery pack and/or working state information of the fluid driving element, and display the power information of the battery pack and/or the working state information of the fluid driving element through a visual interface module.
