Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources and optical lenses are used to form a beam pattern, then illumination function is improved, but stray light irradiates to unnecessary regions causing glare
Solution Approach 1:
The optical lens is divided into multiple light guiding lenses, each responsible for guiding light from a specific light source. This segmentation allows precise control of light paths and prevents stray light from reaching unnecessary regions, resolving the contradiction between beam pattern formation and glare prevention.
Solution Approach 2:
Light guiding lenses serve as intermediary elements between light sources and the external environment. These lenses precisely control light transmission, allowing the system to achieve optimal beam patterns while blocking stray light through the integrated shield structure.
2Object-generated harmful factors
If light guiding lenses are integrated to control light paths, then stray light is blocked, but device complexity increases
Solution Approach 1:
Multiple light guiding lenses are integrated into a single unified structure with a common shield. This merging approach maintains the light control functionality of individual lenses while reducing overall structural complexity and simplifying the optical system assembly.
Solution Approach 2:
The integrated light guiding lens structure performs multiple functions simultaneously: guiding light from multiple sources, forming beam patterns, and blocking stray light through the shared shield. This multi-functionality reduces the need for separate components, thereby lowering device complexity.
3Length of moving object
If multiple light sources are arranged vertically, then slim exterior design is achieved, but light control becomes more difficult
Solution Approach 1:
The vertical arrangement of multiple light sources is managed by segmenting the optical system into multiple light guiding lenses, each handling light from a specific source. This segmentation simplifies light path control despite the compact vertical configuration, maintaining both slim design and effective light management.

Function Achieved in This Case
The design achieves a slim aesthetic appearance while forming a focused beam pattern, reducing glare and improving visibility by blocking and diffusing stray light, enhancing the lamp's functionality and safety.
Implementation Method 1
a transmission portion that transmits at least a portion of the light incident on the incident portion to the exit portion
Implementation Method 2
a reflective surface that reflects light incident on the protruding surface to allow the light to travel toward the exit portion
Implementation Method 3
a shield hole formed between the first light guiding lens and the second light guiding lens to block at least a portion of light incident on the first light guiding lens
