Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a static cigarette is used for combustion test, then the test setup is simple, but the test data fails to reflect the actual smoking process performance
Solution Approach 1:
The patent applies the dynamics principle by transforming the static cigarette test into a dynamic simulation system. The robotic arm moves the cigarette holder along a predetermined trajectory that mimics human arm motion during smoking, while the air exhauster creates variable airflow conditions. This dynamic approach allows the system to replicate the complex interactions between moving cigarette, airflow, and ash behavior that occur in real smoking scenarios, thereby significantly improving measurement precision without requiring excessive complexity.
Solution Approach 2:
The patent employs the copying principle by creating a simulated smoking environment that replicates key characteristics of actual human smoking behavior. The robotic arm copies the motion trajectory of a human arm from mouth to ashtray, the air exhauster copies outdoor wind conditions, and the entire system copies the essential dynamics of real smoking. This copying approach enables accurate measurement of ash integration performance under conditions that closely mirror actual usage, resolving the contradiction between measurement accuracy and equipment simplicity.
2Measurement precision
If indoor static environment is used for test, then the environment is stable, but it cannot simulate outdoor wind speed influence on columnar ash
Solution Approach 1:
The patent applies pneumatics by using an air exhauster to generate controlled airflow that simulates outdoor wind conditions. The air exhauster creates variable air currents that pass over the burning cigarette and columnar ash, replicating the effect of wind on ash stability in outdoor smoking environments. This pneumatic approach allows the system to introduce controlled airflow disturbances that accurately represent real-world conditions, improving environmental simulation accuracy while managing airflow effects systematically rather than allowing uncontrolled disturbances.
Solution Approach 2:
The patent employs parameter changes by varying the airflow parameters (speed, direction, intensity) generated by the air exhauster to match different outdoor wind conditions. The system can adjust airflow parameters to simulate calm outdoor conditions as well as windy conditions, enabling comprehensive testing of ash integration performance under various environmental parameters. This ability to change parameters allows accurate environmental simulation while maintaining controlled experimental conditions.
3Measurement precision
If cigarette is held stationary during combustion, then measurement is simple, but it cannot simulate human arm swinging motion from smoking point to ashtray
Solution Approach 1:
The patent applies the dynamics principle by using a robotic arm to move the cigarette holder along a predetermined trajectory that replicates human arm motion during smoking. The system transitions from static positioning to dynamic movement, capturing the swinging motion from the smoking point to the ashtray. This dynamic motion simulation is essential for accurately measuring ash integration performance, as the movement affects airflow patterns and ash behavior in ways that static testing cannot capture.
Solution Approach 2:
The patent employs the copying principle by using the robotic arm to copy the motion trajectory of a human arm during the smoking process. The system replicates the characteristic swinging motion, the path from mouth to ashtray, and the timing of movements. By copying these essential motion characteristics, the system achieves accurate simulation of smoking actions without requiring a complex anthropomorphic replica, thus improving measurement precision with moderate device complexity.

AI summary
A robotic arm includes a base, a first robotic arm, a second robotic arm, a robotic hand and a cigarette holder connected in sequence. The cigarette holder includes a cigarette insertion hole and a cigarette smoking tube. The cigarette smoking tube is connected to a smoking simulator. The robotic arm further includes at least one air exhausting hole. The air exhausting hole is located around the cigarette holder and communicated with an air exhauster through an air exhausting pipe. The robotic arm swings to control the cigarette holder to carry a cigarette from a smoking position to an ash flicking position. Airflow is formed near the air exhausting hole by means of air exhaustion, so as to simulate influences of a wind speed in an outdoor environment on the columnar ash in the cigarette smoking process of the human body.
