Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional heated hoses in plural component dispensing systems simultaneously receive electrical energy, leading to potential inefficiencies and challenges in independently controlling the temperature of each hose.
Innovation Solution
The system employs independent electrically heated hoses, where a controller alternates the supply of electric current to each hose, allowing for independent temperature control and resistance measurements without separate temperature sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single circuit is used to heat both hoses simultaneously, then the system structure is simplified, but independent temperature control of each hose is lost
Solution Approach 1:
The patent divides the heating system into two independent heating circuits, with each circuit dedicated to heating one hose. This segmentation allows independent control of temperature for each hose, resolving the contradiction between simplified structure and independent temperature control capability.
2Measurement precision
If separate temperature sensors and measurement circuits are used for each hose, then temperature control precision is improved, but system complexity and cost increase
Solution Approach 1:
The patent makes the single measurement circuit multi-functional by enabling it to measure temperature of either hose through alternating excitation. The same circuit serves both measurement purposes at different time intervals, achieving precise temperature control without increasing system complexity or cost.
Solution Approach 2:
The measurement circuit operates periodically by alternating between measuring the first hose and the second hose. This periodic switching allows the single circuit to gather temperature data from both hoses over time, maintaining measurement precision while avoiding the need for separate continuous measurement circuits for each hose.
3Temperature
If electrical current is continuously supplied to both hoses, then heating effectiveness is maximized, but energy consumption increases
Solution Approach 1:
The patent implements periodic heating by alternating the supply of electrical current between the two hoses. At any given time, only one hose receives heating power while the other maintains temperature passively. This periodic heating strategy reduces overall energy consumption while still maintaining adequate temperature in both hoses through thermal inertia and alternating reinforcement.

Function Achieved in This Case
This approach enables efficient and precise temperature control of each fluid component, improving the mixing and properties of the activated plural component spray material, while also reducing costs by eliminating the need for separate measurement circuits.
Implementation Method 1
The heated hoses increase the temperature of the material components flowing through each hose to a desired temperature, ensuring a proper activated mixture is achieved. Traditional heated hoses simultaneously receive a supply of electrical energy to increase the temperature through resistance heating of the hose.

AI summary
A plural component dispensing system includes a first heated hose, a second heated hose, a controller, and a dispensing device. The first heated hose and the second heated hose include electrical wires that supply heat to the first and second heated hoses to heat fluid components within the first and second heated hoses. The first and second heated hoses are electrically coupled to the controller and are fluidly coupled to the dispensing device. The controller is configured to control and alternate the electrical power supplied to the first heated hose and the second heated hose to heat the first heated hose independent of the second heated hose.
