Solution Overview
Problem
Conventional fluid dispensing systems, whether manually operated or air-driven, face challenges in accurately controlling the amount of fluid dispensed, leading to inefficiencies and inconsistencies, and lack portability due to the need for a direct pressurized air source.
Innovation Solution
A portable and programmable cartridge-based fluid dispensing apparatus that uses a controller and stepper motor to generate positive and negative pressures within a fluid cartridge, allowing for precise and reproducible dispensing of a given volume of fluid through a drive rod and piston mechanism, with control signals received from a base station via wired or wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional air-driven mechanisms are used to dispense fluid, then fluid can be dispensed to a worksite, but the system lacks portability due to the need for a direct pressurized air source
Solution Approach 1:
The invention extracts the air source requirement from the dispensing system by using a battery-powered motor instead. The motor drives a rack and pinion mechanism that moves a plunger to dispense fluid, eliminating the need for a pressurized air source and thereby improving portability while maintaining dispensing functionality.
2Measurement precision
If manually-operated mechanical mechanisms are used to dispense fluid, then the system is simple and portable, but the user has difficulty accurately controlling the amount of fluid dispensed
Solution Approach 1:
The controller receives feedback about the dispensing process and adjusts the motor operation accordingly to achieve precise control over the amount of fluid dispensed. The system can be programmed to dispense specific volumes by controlling the motor's rotation and the plunger's movement, ensuring accurate fluid delivery while maintaining system simplicity.
Solution Approach 2:
The invention replaces the manual mechanical operation with an electric motor-driven system. The motor, controlled by a programmable controller, precisely controls the plunger's movement through a rack and pinion mechanism, enabling accurate control of fluid dispensing amounts while maintaining ease of use.
3Productivity
If conventional fluid dispensing systems are used, then fluid can be dispensed, but there are inefficiencies and inconsistencies in the dispensing process
Solution Approach 1:
The invention replaces manual or air-driven mechanical systems with a controlled electric motor system. The motor drives a rack and pinion mechanism that precisely controls plunger movement, ensuring consistent and reliable fluid dispensing. The programmable controller ensures repeatable dispensing operations, improving both efficiency and consistency.
Solution Approach 2:
The system uses a dynamically controlled motor that can adjust its operation based on programmed parameters. The motor's speed and position are controlled to optimize the dispensing process, allowing for efficient and consistent fluid delivery. The system can adapt its operation to achieve precise dispensing results reliably.
