Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If fluorescent tubes are used for product lighting, then energy efficiency is improved, but luminosity and adaptability are reduced
Solution Approach 1:
The patent divides the lighting system into multiple independent LED modules that can be individually controlled. Each module contains multiple LEDs of different colors that can be independently adjusted, allowing the system to achieve high luminosity while maintaining energy efficiency through selective activation of only the needed light sources.
Solution Approach 2:
The patent implements dynamic control of LED intensity and color through a control device that reads product information and automatically adjusts lighting parameters. This dynamic adaptation allows the system to optimize luminosity for each product while consuming minimal energy, resolving the contradiction between high luminosity and energy efficiency.
2Illumination intensity
If incandescent bulbs are used for product lighting, then luminosity is improved, but heat generation and energy consumption increase
Solution Approach 1:
The patent replaces traditional incandescent bulb heating-based illumination with LED electroluminescence technology. LEDs produce light through electrical excitation of semiconductor materials, generating minimal heat compared to the thermal radiation of incandescent bulbs. This substitution maintains high luminosity while dramatically reducing heat generation and energy consumption.
3Device complexity
If fixed lighting sources are used, then device complexity is reduced, but adaptability and flexibility are limited
Solution Approach 1:
The patent creates a universal lighting system where a single LED module can serve multiple products by reading their information carriers and automatically adjusting lighting parameters. The control device enables one lighting unit to adapt to different product types, colors, and requirements, providing high versatility without requiring multiple specialized lighting fixtures or frequent manual reconfiguration.
Solution Approach 2:
The patent implements self-service functionality where the lighting system automatically reads product information from information carriers, processes the data, and adjusts its own lighting parameters without human intervention. This automation maintains system simplicity while achieving high adaptability, as the system independently configures itself for each product.
4Temperature
If spotlights are positioned at a distance from products, then heat impact on products is reduced, but lighting effectiveness and flexibility are diminished
Solution Approach 1:
The patent employs thin LED light sources that can be positioned in close proximity to products without excessive heat transfer. The compact LED modules emit focused light directly onto the product surface, achieving high lighting effectiveness. The low heat output of LEDs allows intimate positioning for optimal illumination angles and coverage, unlike distant spotlights that suffer from light diffusion and reduced effectiveness.

AI summary
A product display system has a product carrier and a lighting device including a plurality of light sources, each having two or more LEDs of different light color, and a control device. The control device can control the various light sources, and even the various LEDs in the light sources, in order, in this way, to achieve a different luminosity and/or light color per light source. The control device reads an information carrier having information associated with the product, and adjusts a light source which illuminates a place of the product carrier designed for the product on the basis of information read from the information carrier.
