Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid pumps with integrated valves face wiring complexity and high component costs due to separate wiring bundles for power and control signals between the fluid pump and valve actuator, which are packaged as a single unit.
Innovation Solution
An apparatus and system using a lead-frame and bridge-frame with electrical conductors to electrically connect the valve section to a motherboard, integrating power and control signals for both the pump motor and actuator motor, reducing the need for separate wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate wiring bundles are used to connect the fluid pump and valve actuator to the central computer, then each device can be independently controlled, but wiring complexity and component costs increase
Solution Approach 1:
The patent combines the pump motor and valve actuator into a single integrated assembly with a common housing. The motor shaft of the pump motor directly drives the valve actuator mechanism, eliminating the need for separate wiring bundles. A single motor driver controls both components through integrated electrical connections, reducing wiring complexity while maintaining independent control capability through electronic signal management.
2Reliability
If separate wiring bundles are used for power and control signals, then signal transmission is reliable, but component costs increase
Solution Approach 1:
The integration of pump and valve actuator reduces the total number of wiring bundles and connectors required. The shared housing and integrated motor assembly allow for common power supply connections and reduced signal routing complexity, directly lowering component costs while maintaining reliable signal transmission through optimized electrical pathways.
Solution Approach 2:
The single motor driver serves multiple functions by controlling both the pump motor and valve actuator. The integrated electrical architecture allows one driver to manage power delivery and control signals for both components, reducing the need for separate drivers and associated wiring infrastructure, thereby reducing component costs while ensuring reliable operation.
3Volume of moving object
If the valve actuator motor is located within the same housing as the pump motor, then the device is compact and integrated, but electrical connectivity becomes complex
Solution Approach 1:
The pump motor and valve actuator are housed in a common housing with integrated mounting structures. The motor shaft directly couples to the valve actuator mechanism, creating a mechanically integrated assembly. Electrical connections are simplified through shared power supply terminals and integrated wiring pathways within the housing, reducing connectivity complexity despite the integrated layout.

AI summary
An apparatus and system for coupling electrical signals between a valve section and a motherboard located in a pump section of an integrated valve and fluid pump device. The apparatus and system includes a lead-frame located in the valve section having a plurality of lead-frame electrical conductors connected to at least one electrical component located in the valve section. A bridge-frame having a plurality of bridge-frame electrical conductors is connected to the motherboard on a first terminal end and to the lead-frame electrical conductors on a second terminal end. The bridge-frame couples the electrical signals between the motherboard and the lead-frame and the electrical component in the valve section.
