Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional pump mechanism is used to dispense formula, then the formula can be dispensed, but the device produces noise and increases mechanical complexity
Solution Approach 1:
The patent replaces the traditional mechanical pump system with a magnetic field-driven piston mechanism. The piston contains a magnetic element that responds to magnetic fields generated by the dispensing device, eliminating the need for mechanical pumps, motors, and associated moving parts. This substitution reduces mechanical complexity while maintaining the dispensing function and significantly reduces noise.
2Reliability
If a mechanical pump is used for dispensing, then formula can be dispensed, but the cost of the device increases
Solution Approach 1:
By replacing expensive mechanical pump components with a simple magnetic-responsive piston system, the patent reduces manufacturing costs. The piston can be manufactured as a simple plastic component with an embedded magnetic element, eliminating the need for costly mechanical assemblies, seals, and moving parts required by traditional pump systems.
3Measurement precision
If no measurement mechanism is implemented, then the device is simpler, but the amount of remaining formula cannot be accurately measured
Solution Approach 1:
The patent introduces a magnetic element within the piston that acts as an intermediary for measurement purposes. This magnetic element interacts with magnetic sensors in the dispensing device to provide information about the piston position and remaining formula volume, enabling accurate measurement without requiring complex mechanical measurement mechanisms within the applicator itself.

AI summary
A method of dispensing a formula, the method comprising attaching an applicator filled with a formula to a dispensing device, identifying the formula by reading the contactless chip on the applicator with a contactless reader on the dispensing device, generating a magnetic field with one or more magnets, wherein the magnetic field moves a piston magnet connected to a piston, and dispensing the formula as the piston moves.
