Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If electrical vaporization is used to atomize liquid, then atomization can be achieved, but the device requires battery or accumulator that must be replaced or recharged

Engineering Contradiction:
Improveatomization capabilityVSAvoidelectrical components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the electrical vaporization system with a mechanical pressurization system. A spring device mechanically pressurizes the liquid reservoir, forcing liquid through fine nozzle openings to achieve atomization without any electrical components, batteries, or accumulators.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses hydraulic pressure generated by a spring device to atomize the liquid. The spring pressurizes the liquid in the reservoir, and this pressure forces the liquid through the nozzle openings, creating an aerosol without requiring electrical heating elements.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Ease of operation

If propellant gas is used to atomize liquid, then atomization can be achieved, but the user also inhales the propellant gas

Engineering Contradiction:
Improveatomization capabilityVSAvoidpropellant gas inhalation
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the propellant gas system with a mechanical spring pressurization system. Instead of using compressed gas to force liquid through nozzles, a solid spring device provides the mechanical pressure, eliminating the need for inhalable propellant gases.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts and removes the propellant gas component from the system entirely. By using a spring device instead, the harmful propellant gas is completely eliminated from the atomization process, leaving only the therapeutic liquid to be delivered to the user.

Inventive Principle:
Principle #2Taking out (Extraction)

3Manufacturing precision

If small nozzle openings are used for fine atomization, then liquid can be effectively atomized, but the nozzle openings are prone to clogging by particles

Engineering Contradiction:
Improveatomization finenessVSAvoidnozzle clogging
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent implements preliminary filtration of the liquid before it reaches the nozzle openings. A filter is positioned upstream of the nozzles to remove particles and impurities from the liquid, preventing them from clogging the fine nozzle openings while maintaining effective atomization.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces a filter as an intermediary component between the liquid reservoir and the nozzle openings. This filter mediates the flow of liquid, capturing particles that would otherwise clog the nozzles, while allowing the liquid to pass through for atomization.

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The oral dispenser effectively atomizes and delivers nicotine or cannabis-containing liquids without the need for electrical components or drift gases, providing a user-friendly alternative for smoking cessation and respiratory health management.

AI summary

The invention relates to an oral dispenser (10) for discharging a liquid in atomized form, in particular for discharging a liquid containing nicotine or cannabis. This oral dispenser (10) has a liquid reservoir (20) of variable internal volume for receiving the liquid prior to the discharge, and a spring mechanism (30) by means of which, when the spring mechanism (30) is loaded, the liquid in the liquid reservoir (20) is placed lastingly under positive pressure. The oral dispenser (10) moreover has an atomization nozzle unit (40) with at least one nozzle opening (44), and an outlet channel (92) that connects the liquid reservoir (20) to the atomization nozzle unit (40). Provided in the outlet channel (92) is an outlet valve (50) which can adopt an opened state and a closed state. A mouthpiece (12) is provided for inhaling the liquid that is atomized by the atomization nozzle unit (40). The oral dispenser (10) moreover has a refill opening (60) which is separate from the atomization nozzle unit (40) and connected to the liquid reservoir (20), wherein the spring mechanism (30) can be loaded by liquid being fed through the refill opening (60) into the liquid reservoir (20).
