Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional display units are used in handheld Raman spectrometers, then device complexity is reduced, but visibility and usability in all light conditions deteriorates
Solution Approach 1:
The patent applies parameter changes by transitioning from conventional display technologies to OLED (organic light-emitting diode) display technology, which fundamentally changes the display mechanism to achieve high brightness and visibility in all light conditions while maintaining a compact handheld form factor
2Ease of operation
If conventional user input methods are used, then device complexity is minimized, but ease of operation and user interaction quality deteriorates
Solution Approach 1:
The patent replaces conventional mechanical input methods (physical buttons, keyboards) with a multi-touch capacitive screen interface, substituting mechanical interaction with electrical field-based touch detection to enable more intuitive and convenient user operation
Solution Approach 2:
The multi-touch capacitive screen serves multiple functions including data entry, spectrum analysis, interactive guidance, and remote control capabilities, consolidating various user interaction needs into a single universal interface
3Duration of action of moving object
If standard battery capacity is used, then device size and weight are minimized, but duration of action and operational longevity deteriorates
Solution Approach 1:
The patent optimizes the power consumption parameters of various components (OLED display, multi-touch screen, processing unit) to enable the use of high-capacity rechargeable lithium-ion batteries, changing the energy management characteristics to support extended field operations
