Quick-Release Windshield System with Exterior Pull Wire
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The removal of a vehicle windshield is often time-consuming and challenging, especially in emergency situations where rapid and safe removal is critical, and can result in damage to the vehicle interior due to the lack of effective means to cut through the urethane adhesive securing it to the frame.
Innovation Solution
A quick-release windshield system that employs a release wire with a leveraging handle and retaining fasteners to cut through the urethane adhesive from the exterior, allowing for rapid and safe removal of the windshield without damaging the vehicle interior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional windshield removal methods are used, then the windshield can be removed, but the process is time-consuming and may cause damage to the vehicle interior
Solution Approach 1:
A wire cutting tool is pre-installed within the vehicle interior, positioned to contact the urethane adhesive bond between the windshield and flange. The tool includes a cutting element that can be engaged by pulling a release mechanism from the exterior, allowing the adhesive to be severed before windshield removal begins, enabling rapid and damage-free removal
Solution Approach 2:
The wire cutting tool acts as an intermediary device between the exterior release mechanism and the adhesive bond. When activated from the exterior, the wire cuts through the urethane adhesive, separating the windshield from the flange without requiring forceful removal that could damage the vehicle interior
2Strength
If the windshield is secured with urethane adhesive for strong bonding, then the windshield remains firmly attached, but rapid removal becomes difficult without damaging the vehicle interior
Solution Approach 1:
The wire cutting tool is pre-positioned to contact the urethane adhesive bond. Upon activation from the exterior, the wire immediately cuts through the adhesive, breaking the strong bond before removal begins. This allows the windshield to be detached easily without damaging the vehicle interior, while maintaining strong bonding during normal operation
Solution Approach 2:
The wire cutting tool is extracted or deployed from its stored position within the vehicle interior when removal is needed. The wire is pulled through the adhesive bond from the interior, cutting through the urethane sealant and freeing the windshield for removal without damaging surrounding structures
3Reliability
If no interior cutting mechanism is installed, then the vehicle interior remains simple, but emergency windshield removal becomes unsafe and time-consuming
Solution Approach 1:
A wire cutting tool is installed within the vehicle interior as an intermediary device. The wire can be pulled from the exterior to cut through the urethane adhesive bond, enabling rapid and safe windshield removal in emergency situations. The device adds minimal complexity while significantly improving rescue reliability
Solution Approach 2:
The wire cutting tool serves multiple functions: it acts as a cutting element to sever the adhesive bond, a release mechanism when activated from the exterior, and a structural component integrated into the vehicle interior. This multi-functionality improves emergency removal capability without adding excessive complexity

AI summary
A quick-release windshield system is a system that allows the rapid and safe removal of a windshield panel from a windshield frame from the exterior of a vehicle. A release wire is releasably attached onto a seat rim of the windshield frame and may be pulled in order to cut through an adhesive that secures the windshield panel to the seat rim. A first end of the release wire is fixed to the windshield frame while a second end of the release wire is externally located to the windshield frame and may be accessed from the exterior of the vehicle. The release wire may be attached to the seat rim via a plurality of retaining fasteners or adhesively. The release wire is separated from the seat rim and may cut through the adhesive when the release wire is pulled from the exterior of the vehicle.
