Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle radiator covers have inadequate lighting effects, with optical fiber and LED structures either limited to peripheral light emission or causing driver distraction due to concentrated light, and lack variation in lighting patterns.
Innovation Solution
A luminous radiator cover device featuring a looped frame with hollow light-transmissive ribs and integrated lighting units, controlled by a unit that adjusts light frequency, brightness, and color in response to sound and temperature, and includes light diffusion ribs for uniform light distribution, preventing dazzling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If optical fiber cord is embedded in cover frame periphery for illumination, then lighting coverage is provided, but lighting effect is inferior due to peripheral radiation only
Solution Approach 1:
The patent divides the lighting function into multiple independent lighting units distributed across the radiator cover surface, rather than using a single peripheral optical fiber cord. Each lighting unit contains multiple light-emitting elements arranged in specific patterns, enabling segmented illumination zones that can be independently controlled for enhanced lighting effectiveness.
Solution Approach 2:
The patent transitions from one-dimensional peripheral lighting (optical fiber along the frame edge) to two-dimensional surface lighting by embedding lighting units directly into the radiator cover body. This dimensional expansion allows light to be emitted from multiple positions across the cover surface, dramatically improving lighting coverage and effect.
2Illumination intensity
If LED lighting structure is installed in cover frame with concentrated frontward radiation, then lighting coverage is improved, but driver safety is compromised due to dazzling effect
Solution Approach 1:
The patent applies different lighting characteristics to different regions of the radiator cover. Lighting units positioned in specific areas emit light at different intensities and angles, with those closer to the driver's line of sight using lower intensity or diffused emission patterns, while other areas provide stronger illumination. This localized quality variation ensures adequate lighting coverage without creating dazzling effects that distract drivers.
3Adaptability or versatility
If conventional lighting structures are used, then basic illumination is provided, but lighting effect lacks variation and adaptability
Solution Approach 1:
The patent incorporates control units that enable dynamic adjustment of lighting patterns, intensities, and colors based on various conditions such as ambient light levels, vehicle operating state, or external environmental factors. The lighting units can switch between different emission modes (e.g., steady illumination, flashing patterns, color changes), providing adaptability without requiring overly complex control systems.
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
The device achieves varied and safe lighting effects, enhancing visibility and safety by adapting light patterns to sound and temperature changes, while providing direction indication, thus improving market competitiveness and safety.
Implementation Method 1
Each of the lighting units is disposed in the inner receiving space of a corresponding one of the light-transmissive ribs, and is capable of emitting light
Implementation Method 2
a plurality of hollow light-transmissive ribs... Each light-transmissive rib extends in a second direction transverse to the first direction, and is configured with an inner receiving space
