Solution Overview
Problem
Existing drives for whirlpool systems are complex and costly due to the need for secondary circuits to drive high-voltage motors and luminous signals for operation condition indication, with increased manufacturing and installation complexity.
Innovation Solution
A drive system that uses a purely mechanical device accessible at the bathtub edge to control the high-voltage motor switch, eliminating the need for secondary circuits and luminous signal indicators, featuring a rotating knob with a cam mechanism to interact with a switch and indicating operation conditions through distinct mechanical positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If secondary circuits with transformers and relays are used to drive high-voltage motors, then safety is improved by providing a secondary interface, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts and eliminates the complex secondary circuitry (transformers, relays, electronic boards) from the system. Instead of using a secondary low-voltage circuit to control the high-voltage motor, the invention uses a purely mechanical push-button switch that directly actuates the high-voltage circuit through mechanical linkage, thereby maintaining safety while removing electrical complexity.
Solution Approach 2:
The patent replaces the electrical secondary circuit control system with a mechanical control system. The mechanical push-button switch directly mechanically actuates the high-voltage circuit breaker or contactor, eliminating the need for electrical transformation and relay mechanisms while achieving the same control function.
2Loss of information
If luminous signals (LEDs) are used to indicate operation conditions, then user information is improved, but device complexity and cost increase due to additional electrical circuits
Solution Approach 1:
The patent removes the luminous indication system (LEDs, optical fibers, electronic circuits) from the device. Instead of using electrical signals to indicate operation status, the invention uses the mechanical position and visual appearance of the push-button switch itself (pressed vs. released state) to directly indicate the operation condition, eliminating the need for separate indication circuitry.
Solution Approach 2:
The push-button switch serves dual functions: it both controls the motor operation and simultaneously indicates the operation status through its own mechanical position. The switch itself becomes the indicator, eliminating the need for separate luminous or electrical indication systems.
3Adaptability or versatility
If multiple circuits and components are assembled into the drive system, then functionality is improved, but installation complexity increases
Solution Approach 1:
The patent merges the control function and the indication function into a single integrated push-button switch assembly. This consolidation reduces the number of separate components that need to be installed and connected, thereby simplifying installation while maintaining full functionality for both motor control and status indication.
