Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light sources with different functions are included in the flashlight, then lighting functionality and versatility are improved, but device complexity increases due to requiring multiple switches to control each light source
Solution Approach 1:
A single switch is designed to perform multiple functions by selectively activating different light sources based on its actuation state. The switch can activate a first light source, a second light source, or both simultaneously, eliminating the need for separate switches for each light source while maintaining full lighting functionality.
2Adaptability or versatility
If conventional battery configurations are used, then manufacturing simplicity is maintained, but power management flexibility is limited
Solution Approach 1:
The battery system is divided into separate battery compartments that can independently receive one or more batteries. This segmentation allows the device to accommodate different battery configurations (single battery, multiple batteries, different battery types) while maintaining a standardized interface and control mechanism through the single multi-functional switch.
