Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number and type of light source elements are kept uniform in all luminous units, then consistent luminance is achieved, but flexibility and adaptability for different applications are reduced
Solution Approach 1:
The illumination system is divided into multiple independent luminous units, each containing a plurality of light source elements connected in series. Each luminous unit can be independently configured with different numbers of light source elements (e.g., 3, 4, or 5 LEDs per unit) depending on the desired luminance level, allowing customization while maintaining series connection reliability within each unit.
Solution Approach 2:
The system allows dynamic reconfiguration by connecting multiple luminous units in parallel. The number of luminous units can be adjusted based on application requirements, enabling the same base structure to adapt to different luminance needs by simply adding or removing parallel units rather than redesigning the entire system.
2Reliability
If resistor elements are added to compensate for LED forward voltage irregularities, then luminance consistency is improved, but device complexity increases
Solution Approach 1:
The resistor elements are integrated within the same luminous unit structure as the LED elements. Each luminous unit contains both LEDs and resistors connected in series, merging the light-emitting function and the current-regulating function into a single modular unit, which simplifies the overall system architecture despite the added complexity within each unit.
Solution Approach 2:
The system compensates for LED forward voltage variations by introducing resistor elements with specific resistance values into each luminous unit. This parameter adjustment allows each unit to maintain consistent current flow and luminance output despite individual LED variations, achieving reliability through controlled parameter modification.
3Adaptability or versatility
If custom configurations of light source elements are implemented for specific applications, then adaptability is improved, but manufacturing standardization becomes more difficult
Solution Approach 1:
The system is segmented into standardized luminous units that can be manufactured uniformly. Each luminous unit contains a fixed number of LED elements (e.g., 3, 4, or 5) and corresponding resistors connected in series. These standardized modules can then be combined in parallel in different quantities to achieve various total luminance levels, maintaining manufacturing simplicity while providing configuration flexibility.
Solution Approach 2:
The luminous units are designed with universal characteristics that allow them to serve multiple functions. The same basic luminous unit structure can be used across different applications by simply varying the number of parallel units connected, making the manufacturing process standardized while the system remains adaptable to different luminance requirements through modular assembly.
