Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed positioning lamps with batwing light distribution are used, then light emission characteristics are determined, but adaptability to varying shelf arrangements is poor
Solution Approach 1:
The patent applies the dynamics principle by making the lighting units adjustable and movable relative to each other and to the lamp housing. The lighting units can be positioned at different angles and locations to adapt the light distribution curve to various shelf arrangements, transforming a static system into a dynamic one that can be configured for different retail environments.
Solution Approach 2:
The patent divides the lamp into multiple independent lighting units that can be individually adjusted. Each lighting unit contains its own light source and optical components, allowing independent positioning and angle adjustment. This segmentation enables flexible configuration of the overall light distribution pattern to match different shelf layouts.
2Ease of operation
If lenses are used to achieve batwing distribution, then light emission characteristics are fixed, but flexibility in luminaire positioning is limited
Solution Approach 1:
Instead of relying on fixed lenses to determine light distribution, the patent uses adjustable lighting units that can be dynamically repositioned. This allows the light distribution characteristics to be changed by adjusting the physical position and angle of the lighting units, providing both ease of operation and adaptability.
Solution Approach 2:
The patent enables change of light distribution parameters by physically adjusting the lighting units rather than being constrained by fixed optical parameters of lenses. The position, angle, and orientation of each lighting unit can be modified to achieve different light distribution patterns suitable for various shelf configurations.
3Adaptability or versatility
If separate lamps are used for each beam of rays, then light distribution can be controlled, but device complexity increases
Solution Approach 1:
The patent merges multiple lighting units into a single integrated lamp housing while maintaining their individual adjustability. The lighting units share common mounting structures, control mechanisms, and housing, reducing overall device complexity compared to using completely separate lamps while still providing independent control over each light beam.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

AI summary
In a luminaire (100) with two lighting units (10), these are arranged side by side with respect to a longitudinal axis (I) of the luminaire (100) and are designed such that they produce light emission directed away from each other in a plane perpendicular to the longitudinal axis (I) of the luminaire (100), wherein both lighting units (10) are adjustable about a pivot axis (II) which runs parallel to the longitudinal axis (I) of the luminaire (100).
