Flexible Cable Light Guide for Long Vehicle Display Controls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display type control devices in vehicles suffer from decreased visibility due to increased distance between the light emitting body and the display, limiting design flexibility and increasing costs with separate substrates.
Innovation Solution
A display type control device with a housing containing a flexible cable having a light emitting part, guided by guides within the housing, and a light collector to ensure optimal light transmission to the display, allowing for improved visibility and design diversity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between the light emitting body and the display is increased to accommodate longer control device designs, then the design flexibility is improved, but the visibility and brightness of the display deteriorates
Solution Approach 1:
A light guide member is introduced as an intermediary component between the light emitting body and the display. This light guide member transmits and distributes light from the light emitting body to the display, enabling the light emitting body to be positioned at a greater distance while maintaining display brightness and visibility.
2Illumination intensity
If a separate substrate is configured for the knob to maintain display quality, then the screen quality is preserved, but the device complexity and cost increase
Solution Approach 1:
The light emitting body, flexible cable, and light guide member are integrated into a single unified structure. This merging eliminates the need for separate substrates and additional components, reducing device complexity and cost while maintaining display quality through the light guide member.
3Length of moving object
If the distance between the light emitting body and the display is increased, then the control device length can be extended, but the uniformity of illumination deteriorates
Solution Approach 1:
The light guide member acts as a mediator that evenly distributes light from the light emitting body across the display surface. This ensures uniform illumination even when the control device is extended in length, as the light guide member maintains consistent light distribution throughout.
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
Enhances visibility and manipulability of the display, enabling longer designs without additional components and maintaining screen quality, thus diversifying the shape of control devices.
Implementation Method 1
a light emitting part for emitting light is disposed on one surface of the flexible cable
Implementation Method 2
a light collector positioned between the display and the light emitting part and configured to guide light emitted from the light emitting part to the display
