Lamp Apparatus Single Optic Unit Merging Light Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle lamps with signal functions typically require multiple parts for each light source, increasing part costs and assembly time due to their complex installation.
Innovation Solution
A lamp apparatus design that reduces the number of parts by using a single optic unit for multiple light source modules, with a control unit to individually turn on/off the modules, and a fixing plate for precise positioning and spacing of the optic unit, thereby decreasing part costs and assembly time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one optic unit corresponds to one light source, then the lighting function and signal function are well implemented, but the number of parts is increased and part cost is raised
Solution Approach 1:
The patent merges multiple light sources (first and second light sources) into a single optic unit that serves both lighting and signal functions. The optic unit includes a light guide part that distributes light from multiple sources through multiple light entry parts, eliminating the need for separate optic units for each light source and reducing the total number of parts.
Solution Approach 2:
The single optic unit is designed to perform multiple functions simultaneously - it handles both lighting illumination and signal indication. The control unit enables different operating modes (lighting mode and signal mode) using the same optic unit, making it a multi-functional component that replaces what would traditionally require multiple specialized units.
2Reliability
If one optic unit corresponds to one light source, then the lighting function and signal function are well implemented, but the assembling time is increased
Solution Approach 1:
By combining multiple light sources and their corresponding optic units into a single integrated optic unit, the assembly process is simplified. Instead of assembling multiple separate optic units onto multiple light sources, the patent allows for a single optic unit to be assembled onto the light source assembly, significantly reducing assembly time and steps.
3Quantity of substance
If multiple light sources share one optic unit, then the number of parts is decreased and part cost is reduced, but the positioning precision of the optic unit may be affected
Solution Approach 1:
The optic unit is segmented into multiple functional regions with light entry parts positioned at specific locations corresponding to different light sources. The light guide part is divided into first and second light guide parts that independently guide light from respective light sources through specific light entry parts to the light exit part, ensuring precise light paths and positioning.
Solution Approach 2:
The light guide part acts as an intermediary structure that mediates between multiple light sources and the single optic unit. It ensures precise positioning and light transmission by guiding light from each light source through designated light entry parts to the light exit part, maintaining manufacturing precision despite the reduced number of parts.
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 design reduces part costs and assembly time while maintaining efficient light emission and control, allowing for easier installation and reduced weight, while enabling the optic unit to be reliably fixed at a preset position.
Implementation Method 1
a light guide part connected to the optic base part, covering the outer surfaces of the plurality of light entry modules, and configured to guide lights, entering the respective light entry modules, toward the light exit part
Implementation Method 2
The lens unit may diffuse light received from the optic unit
