Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switch mechanisms fail to simultaneously change multiple electrical switches from one state to another in response to a single physical input, leading to inefficiencies in controlling devices like pumps, blowers, and valves.
Innovation Solution
A pressure switch mechanism that uses a diaphragm and fluid chambers to provide a physical input, coupled with a linkage lever and activation lever system, allowing all electrical switches to be actuated or de-actuated simultaneously through a single activation input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple electrical switches are controlled individually, then each switch can be actuated independently, but the operational efficiency decreases and time is lost due to sequential actuation
Solution Approach 1:
The patent combines multiple electrical switches into a single integrated switch mechanism where a diaphragm and linkage system simultaneously actuate multiple switches. The diaphragm responds to pressure differentials and through mechanical linkages transfers motion to multiple switch actuators, enabling simultaneous switching of multiple circuits in response to a single physical input, thereby improving productivity and eliminating time loss associated with sequential actuation.
2Productivity
If a single physical input actuates multiple switches simultaneously, then operational efficiency improves, but the device complexity increases due to the linkage lever and activation lever system
Solution Approach 1:
The diaphragm serves as a universal actuating element that responds to pressure differentials and simultaneously controls multiple switches through its linkage connections. This multi-functional design allows a single component to perform the work of multiple independent actuators, achieving synchronized control of multiple switches while managing complexity through functional integration rather than proliferation of separate components.
Solution Approach 2:
The linkage lever and activation lever system acts as an intermediary mechanism that translates the diaphragm's motion into simultaneous actuation of multiple switches. These levers serve as mechanical mediators that distribute the single input motion from the diaphragm to multiple output points (switch actuators), enabling synchronized control while maintaining a manageable level of mechanical complexity through well-defined transmission paths.
3Reliability
If manual reset is implemented, then the switch can be reset after actuation, but the ease of operation is reduced compared to automatic reset systems
Solution Approach 1:
The switch mechanism incorporates a manual reset feature where the same diaphragm and linkage system that actuates the switches also provides the reset function. When the pressure differential changes, the diaphragm returns to its neutral position, and through the linkage mechanism, automatically resets the switches to their initial state. This self-service approach allows the system to reset itself without requiring external intervention, maintaining reliability while improving ease of operation compared to purely manual reset systems.

Implementation Method 1
a first fluid chamber (34) in fluid communication with a diaphragm (30) and a second fluid chamber (36) in fluid communication with the diaphragm (30). The switches (114) are adapted to be changed from their first states to their second states in response to pressure differentials between the first fluid chamber (34) and the second fluid chamber (36).
Implementation Method 2
