Vehicle Light-Blocking Windshield Layout for Lower Cabin Heat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sunlight entering a vehicle through the windshield increases heat input to the accommodation space, leading to discomfort and increased air conditioning load.
Innovation Solution
A traffic mover with a light blocking member that blocks light entry, incorporating a heat transfer member and a driving assistance unit to enable operation even with blocked views, using a heat insulating material and inclined design to reduce heat input and air resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a windshield is provided to allow forward view, then visibility is improved, but heat input from sunlight increases
Solution Approach 1:
The front surface is divided into two functional zones: an upper light blocking member that blocks sunlight and heat, and a lower transparent windshield that provides forward visibility. This segmentation allows each zone to perform its specific function without compromising the other
Solution Approach 2:
Different parts of the front surface have different optical properties: the upper light blocking member has heat blocking properties while the lower windshield has transparency properties. This local differentiation of quality allows the system to simultaneously achieve heat reduction and visibility
2Temperature
If a light blocking member blocks forward view, then heat input is reduced, but driving capability deteriorates
Solution Approach 1:
The front surface is segmented vertically into a light blocking upper portion and a transparent lower windshield portion, allowing the driver to see through the windshield while the upper portion blocks heat
Solution Approach 2:
The solution moves from a single-dimensional choice (either block light or allow visibility) to a two-dimensional arrangement where vertical positioning creates functional zones: heat blocking at the top and visibility at the bottom
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
Reduces heat input, improves comfort, and decreases air conditioning load while enabling safe and efficient driving through imaging and control systems.
Implementation Method 1
A heating medium for cooling or heating the accommodation space (S) flows through the flow passages (91), and the heat transfer member (90) transfers heat between the heating medium flowing through the flow passages (91) and the air in the accommodation space (S)
Implementation Method 2
a light blocking member (40) that blocks light entering from a front side of the mover body (20) in a moving direction of the mover body (20)
Implementation Method 3
the light blocking member (40) is made of a heat insulating material

AI summary
A mover body (20) has a light blocking member (40) that blocks light entering from a front side of the mover body (20) in a moving direction thereof. The mover body (20) includes a driving assistance unit (60, 70) that enables the mover body (20) to be driven when the light blocking member (40) blocks a forward view of a human (H) in the moving direction of the mover body (20).
