Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED light sources are used to reduce energy consumption, then energy efficiency is improved, but light distribution control and glare reduction become more challenging
Solution Approach 1:
The patent segments the light distribution control by separating the LED light source from the optical control components (lenses, reflectors, baffles). This allows independent optimization of energy efficiency in the LED module while achieving precise light distribution control through the optical components. The modular design enables each segment to be optimized for its specific function.
Solution Approach 2:
The patent introduces optical intermediaries (lenses, reflectors, baffles) between the LED light source and the target area. These intermediary components mediate the light distribution, controlling glare and spill while maintaining the energy efficiency benefits of LED technology. The intermediaries transform the raw LED output into controlled, directional light patterns.
2Ease of manufacture
If standardized LED modules are used to simplify installation, then ease of installation is improved, but customization of lighting patterns becomes limited
Solution Approach 1:
The patent creates a universal LED module design that can be adapted to multiple lighting applications. The standardized module incorporates interchangeable optical components (lenses, reflectors, baffles) that enable the same basic module to achieve different lighting patterns and functions. This multi-functionality allows easy installation while maintaining customization capability.
Solution Approach 2:
The patent enables dynamic customization by allowing different optical component configurations to be applied to the standardized LED module. The system can be dynamically adapted to different lighting requirements by changing the optical intermediaries while keeping the core LED module standardized, thus maintaining both ease of installation and adaptability.
3Loss of energy
If optical control components are added to reduce glare and spill, then light utilization is improved, but device complexity increases
Solution Approach 1:
The patent merges the optical control components (lenses, reflectors, baffles) into an integrated optical assembly that works with the LED module. This combining approach improves light utilization by coordinating multiple optical elements while managing the overall complexity through integrated design. The merged assembly presents a unified interface for installation and adjustment.
Solution Approach 2:
The patent applies local quality optimization by selecting specific optical components (lenses, reflectors, baffles) positioned at particular locations around the LED module based on the desired lighting pattern. Each optical element is strategically placed and configured to address specific local lighting requirements, improving overall light utilization while keeping the complexity localized rather than distributed throughout the entire system.
