Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional decal is used on a vehicle, then the vehicle can display a logo or graphic, but the decal lacks dynamic display capability and cannot indicate operational status
Solution Approach 1:
The decal transitions from a static graphic to a dynamic display element by incorporating a luminescent structure that can be selectively illuminated. The light guide and light source enable the decal to change its visual state based on operational conditions, allowing it to display different information dynamically while maintaining a relatively simple overall structure.
Solution Approach 2:
A light guide structure is introduced as an intermediary between the light source and the luminescent decal. This light guide efficiently directs light to the decal, enabling dynamic illumination without requiring the light source to be in direct contact with the decal, thus maintaining structural simplicity while achieving dynamic display capability.
2Illumination intensity
If a luminescent structure with light guide is integrated into the vehicle window, then the indicia can be dynamically illuminated to enhance attractiveness and provide information, but the structural complexity increases
Solution Approach 1:
The luminescent structure is integrated directly into the vehicle window assembly, merging the decal, light guide, and lighting components into a unified window structure. This integration eliminates the need for separate mounting systems and reduces overall structural complexity while achieving dynamic illumination of indicia.
Solution Approach 2:
The vehicle window serves multiple functions: it provides the structural barrier function of a window, while simultaneously housing the luminescent indicia display system. The window structure itself becomes the mounting platform for the light guide and luminescent elements, eliminating the need for additional structural components.
3Illumination intensity
If the light source is continuously activated, then the indicia are always visible and attractive, but energy consumption increases
Solution Approach 1:
The light source is activated periodically or on-demand based on specific conditions rather than continuously. The controller activates the light source only when relevant information needs to be displayed, such as when the vehicle is in a particular operational state or when a user interacts with the system, thereby reducing overall energy consumption while maintaining visibility when needed.
Solution Approach 2:
The system incorporates a controller that monitors operational status and user interactions, and selectively activates the light source based on this feedback. This feedback mechanism ensures the indicia are illuminated only when information needs to be communicated, optimizing energy usage while maintaining visibility functionality.
