Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display-type component or multiple light-emitting diodes are included in the aerosol generating device, then visual information can be displayed to the user, but the material cost and number of components increase, failing to meet miniaturization and weight reduction trends
Solution Approach 1:
The patent merges the functions of multiple light-emitting diodes into a single light-emitting diode by using different control modes (blinking patterns and brightness levels) to convey various visual information, thereby reducing the number of components while maintaining information display capability
Solution Approach 2:
The single light-emitting diode is designed to perform multiple functions by varying its operational characteristics (blinking vs. steady light, different brightness levels) to indicate different device states, replacing what would traditionally require multiple dedicated indicators
2Loss of information
If a display-type component or multiple light-emitting diodes are included in the aerosol generating device, then visual information can be displayed to the user, but the material cost increases
Solution Approach 1:
The patent consolidates multiple light-emitting diodes into a single component, directly reducing material costs while maintaining the ability to display various visual information through controlled operational patterns
3Device complexity
If a single light source is used with controlled power supply modes, then manufacturing costs are reduced and miniaturization is achieved, but the ability to provide clear visual information for different device states must be maintained
Solution Approach 1:
The patent employs dynamic control of the single light-emitting diode by switching between different operational modes (blinking pattern for binary state changes, adjustable brightness for continuous values) to clearly communicate different device states to the user
Solution Approach 2:
The patent utilizes brightness level variations of the single light-emitting diode to convey different information, with higher brightness indicating certain states and lower brightness indicating other states, providing clear visual differentiation
