Frameless Car Unlocking Tool With Lever-Bending Hook Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to manually unlock automotive vehicles with frameless windows, particularly TESLA vehicles, when the key is unavailable or the 12-volt battery system is dead, without causing damage to the delicate laminate glass or vehicle components.
Innovation Solution
A tool comprising an elongated strip with a hook and a control wire is used to manually unlock the vehicle by inserting it between plastic shields in the space between the glass window and weatherstripping, allowing manipulation from outside to engage the manual release lever.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional unlocking methods are used on vehicles with frameless windows, then the vehicle can be unlocked, but the delicate laminate glass may be damaged
Solution Approach 1:
The patent introduces plastic shields as intermediary protective elements between the unlocking tool and the glass window. These shields are inserted into the gap between the glass and weatherstripping, allowing the tool to engage the door mechanism without direct contact with the glass, thus preventing damage while enabling unlocking
Solution Approach 2:
The unlocking tool is segmented into distinct functional components: an elongated strip for insertion, plastic shields for protection, and a control wire for actuation. This segmentation allows each component to perform its specific function - the shields protect the glass while the strip and wire provide the unlocking mechanism
2Ease of operation
If the vehicle door is pried open to access the interior, then the door can be opened, but the glass window may break
Solution Approach 1:
The plastic shields serve as mediators that enable door opening operations without direct tool contact with the glass. The shields are positioned between the tool and glass, transmitting the mechanical action of door prying while protecting the glass from damage
Solution Approach 2:
The plastic shields provide beforehand cushioning protection by being pre-positioned in the gap between the glass and weatherstripping before the unlocking operation begins. This preventive measure cushions against potential impact forces during the door opening process
3Length of moving object
If a tool is inserted between glass and weatherstripping to unlock the door, then the door release lever can be actuated, but the tool must be long enough to reach inside the vehicle
Solution Approach 1:
The tool is divided into multiple segments: an elongated insertion strip, separate plastic shields, and an attached control wire. This segmentation allows the tool to achieve the necessary length to reach the door release lever while maintaining manageable complexity through modular construction
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 tool effectively unlocks the vehicle without damaging the glass or other components, ensuring safe access even in emergency situations.
Implementation Method 1
a control wire, cord, or line operatively connected to the elongated strip of metallic material at the distal end that causes the distal end to bend when pulled at the operator proximate end
Data Source
AI summary
A tool designed to manually unlock automotive vehicles with frameless windows including TESLA® vehicles from the outside of the vehicle is described. The tool includes an elongated strip of material having an operator proximate end and terminating at a hook at a distal end, and a control wire, cord, or line operatively connected to the elongated strip of metallic material at the distal end that causes the distal end to bend when pulled at the operator proximate end. A kit and a method featuring the tool are also described.
