Transparent A-Pillar with Embedded Wiring for Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current adjustable seating systems and reduced A-pillar widths do not provide adequate visibility to blind spots, posing safety concerns, and minimizing pillar widths compromises structural performance and passenger safety.
Innovation Solution
A fiber-reinforced vehicle A-pillar with a transparent opening made of materials like polycarbonate or PMMA, embedded with resistance wiring for defogging and deicing, and strategically oriented reinforcing fibers to maintain structural integrity while enhancing visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the A-pillar width is reduced to improve driver visibility, then the blind spot is reduced, but the structural performance and passenger safety are compromised
Solution Approach 1:
The A-pillar is segmented into three functional zones: transparent opening sections (for visibility), opaque structural sections (for strength), and reinforced fiber sections (for structural integrity). This segmentation allows each zone to perform its specific function optimally without compromising overall pillar performance
Solution Approach 2:
The patent employs composite materials including transparent polycarbonate or PMMA plastic sections combined with opaque structural sections and reinforcing fiber sections. These composite materials provide both optical transparency where needed and structural strength where required, resolving the contradiction between visibility and structural performance
2Ease of operation
If adjustable seating systems are used to improve visibility, then drivers can adjust to their stature, but blind spots hidden by the A-pillar structure remain
Solution Approach 1:
The patent extracts the obstructing portion of the A-pillar by creating a transparent opening that removes the solid material blocking the driver's view. This extraction of the obstructing element directly addresses the blind spot problem that seating adjustments cannot resolve
3Area of stationary object
If the A-pillar width is reduced to improve visibility, then the field of view is enhanced, but the pillar can no longer maintain structural integrity
Solution Approach 1:
The A-pillar is designed with varying local qualities: transparent sections with specific optical properties for visibility, opaque sections with high structural properties for strength, and reinforced sections with enhanced mechanical properties. Each local region is optimized for its specific function
Solution Approach 2:
The patent adds dimensional complexity by incorporating reinforcing fibers oriented in specific directions within the pillar structure. This dimensional reinforcement allows the pillar to maintain structural integrity despite reduced overall width, enabling larger transparent openings
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 solution improves driver visibility without reducing the vehicle frame's size, maintaining structural performance and safety, by creating a transparent opening that optimizes the field of view while allowing for increased pillar width.
Implementation Method 1
The transparent material is selected from materials having a transmission coefficient of at least 50 percent for light in the infrared (IR), visible, and ultraviolet (UV) wavelengths
Implementation Method 2
resistance wiring is embedded within the transparent material. The resistance wiring provides defogging and/or deicing for the optically transparent portion

AI summary
Technical methods described herein include a motor vehicle frame having an improved field of view. The motor vehicle frame includes a pillar body, such as an A-pillar, having an opening positioned between opposite sidewalls of the pillar body. A transparent material is disposed within the opening in the pillar body. The transparent material is selected from materials having a transmission coefficient of at least 50 percent for light in the infrared (IR), visible, and ultraviolet (UV) wavelengths and a refractive index between 1 and 2 for visible light, such as polymethylmethacralate (PMMA) or an optically transparent polycarbonate.
