Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If field testing is performed with multiple illumination schemes, then lighting performance can be evaluated, but delays and additional expenses occur due to repeated setups and purchases of lighting equipment
Solution Approach 1:
The patent applies universality by creating a standardized test fixture that can evaluate multiple illumination schemes (different light sources, mounting configurations, and optical arrangements) without requiring separate fixtures for each scheme. This single versatile fixture replaces the need to purchase and set up multiple specialized fixtures, directly resolving the contradiction between evaluation comprehensiveness and setup time
Solution Approach 2:
The patent implements preliminary action by pre-configuring the test fixture with standardized mounting mechanisms, adjustable optical components, and interchangeable test targets. These preliminary preparations allow rapid reconfiguration between different illumination schemes during field testing, eliminating the need for time-consuming setup procedures each time a new scheme is evaluated
2Measurement precision
If field testing is performed with multiple illumination schemes, then lighting performance can be evaluated, but additional expenses occur due to purchases of lighting equipment
Solution Approach 1:
The standardized test fixture serves multiple functions by accommodating various light sources (LED, HID, fluorescent), different mounting styles (surface mount, recessed, pendant), and multiple optical configurations. This multi-functional design eliminates the need to purchase separate specialized fixtures for each illumination scheme, directly addressing the contradiction between evaluation capability and equipment quantity
Solution Approach 2:
The patent uses a standardized test fixture that creates a reproducible reference framework for evaluating different illumination schemes. Rather than purchasing multiple physical fixtures, the system uses this single standardized fixture to 'copy' or replicate testing conditions across different schemes, reducing equipment requirements while maintaining evaluation accuracy
3Loss of information
If computer-based lighting models are created, then illumination schemes can be visualized, but the models may not accurately represent the light distribution due to errors in inputs or site conditions
Solution Approach 1:
The standardized test fixture acts as an intermediary between computer-based lighting models and actual field installation. It provides a physical reference framework that validates and calibrates the digital models, ensuring that the virtual representations accurately reflect real-world light distribution by comparing modeled predictions against measurements taken using the standardized fixture
Solution Approach 2:
The patent implements feedback by using the standardized test fixture to measure actual light distribution and comparing these measurements against computer model predictions. This feedback loop allows for validation and correction of model inputs, improving the accuracy of future simulations by identifying and correcting discrepancies between modeled and actual performance
4Adaptability or versatility
If on-site evaluation is performed, then customer expectations can be assessed, but considerable planning and equipment setup are required prior to customer viewing
Solution Approach 1:
The standardized test fixture provides a universal platform that can demonstrate multiple illumination schemes and configurations without requiring different equipment setups for each demonstration. This versatility allows the evaluator to assess various options and gauge customer expectations using the same physical framework, reducing the complexity and planning required compared to setting up separate demonstrations for each scheme
Solution Approach 2:
The test fixture incorporates dynamic, adjustable components such as interchangeable optical elements, adjustable mounting angles, and replaceable test targets. These dynamic features allow rapid reconfiguration during the evaluation process without requiring complete setup changes, enabling flexible demonstration of multiple illumination schemes while maintaining simple, consistent equipment infrastructure
