Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional lighting control systems are used, then lighting control functionality is provided, but the system becomes expensive and inflexible
Solution Approach 1:
The handheld device serves multiple functions: capturing images of the space, analyzing luminance levels from the images, receiving user lighting parameters, and controlling lighting devices. By consolidating these diverse functions into a single universal device, the system achieves flexibility without requiring multiple specialized components, thereby reducing overall system complexity and cost.
Solution Approach 2:
The system replaces traditional manual mechanical dimmer controls with an automated digital control approach. The handheld device captures images, processes luminance data through algorithms, and sends wireless control commands to lighting devices, substituting manual mechanical adjustment with automated optoelectronic control that is both more flexible and less complex.
2Speed
If lighting fixtures are adjusted manually, then lighting control is achieved, but time is required for fixtures to reach steady state
Solution Approach 1:
The system performs preliminary analysis of the space by capturing images and calculating luminance levels before actual lighting control is applied. This preliminary action allows the system to pre-determine appropriate lighting parameters, enabling faster adjustment to steady state without requiring lengthy manual trial-and-error adjustments or waiting for gradual stabilization.
Solution Approach 2:
The system implements a feedback loop where the handheld device captures images of the illuminated space, analyzes the actual luminance levels, compares them with target values, and adjusts lighting device parameters accordingly. This closed-loop feedback mechanism enables rapid convergence to the desired steady state by continuously monitoring and correcting lighting conditions, significantly reducing stabilization time compared to manual adjustment.
