Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a handheld cigarette purifier is designed with separate insertion steps (cigarette into holder, then holder into device), then the structure can be simple, but the operation becomes inconvenient and risks of scalding and ash falling increase

Engineering Contradiction:
Improveoperation convenienceVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cigarette holder and purification device are integrated into a single unified structure. The cigarette holding chamber is directly formed within the purification device housing, eliminating the need for separate holder and device components. This merging allows users to insert the cigarette directly into the chamber without intermediate steps, improving operational convenience while maintaining structural simplicity through functional integration.

Inventive Principle:
Principle #5Merging (Combining)

2Object-generated harmful factors

If the cigarette is inserted into the purification device after being lit, then the device structure can be simpler, but smoke gas is generated and pollutes the environment before purification

Engineering Contradiction:
Improvesecondhand smoke pollutionVSAvoidstructure complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The cigarette-lighting device is pre-positioned within the cigarette holding chamber at the opposite end from the chamber opening. This preliminary arrangement of the lighting component allows the cigarette to be lit automatically upon insertion, ensuring the burning cigarette remains contained within the purification device from the moment of ignition, thereby preventing unfiltered smoke release into the environment.

Inventive Principle:
Principle #10Preliminary action

3Object-generated harmful factors

If check valves are added to control airflow direction, then smoke containment is improved, but device complexity increases

Engineering Contradiction:
Improvesmoke leakageVSAvoidstructure complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

Check valves are integrated into the airflow pathways at the air intake port and air inlet of the smoke purification device. These valves utilize pneumatic pressure differential to automatically control airflow direction - allowing air to flow only toward the cigarette holding chamber and smoke purification device respectively, while preventing reverse flow. This pneumatic control mechanism ensures smoke containment without requiring complex mechanical or electronic control systems.

Inventive Principle:
Principle #29Pneumatics and hydraulics

AI summary

An automatic cigarette-lighting purifier includes a cigarette holding chamber and a smoke purification device, one end of the cigarette holding is provided with a chamber opening which is communicated with the smoke purification device and the cigarette holding chamber, and a cigarette positioning member is provided at the chamber opening. The automatic cigarette-lighting purifier further includes a ventilation end cap that is movable to cover the end of the cigarette holding chamber that is opposite to the chamber opening, and a cigarette-lighting member is at one side of the ventilation end cap. A cigarette can be lighted automatically by the cigarette-lighting device once it's placed in the automatic cigarette-lighting purifier, and the burned cigarette is always kept in the automatic cigarette-lighting purifier, thus no unfiltered second-hand smoke is produced. Furthermore, the structure of the automatic cigarette-lighting purifier according to the present invention is simple, the operation is convenient, and the possibilities of scalding and cigarette ash falling are prevented.
