Solution Overview
Problem
Existing window-breaking emergency escape devices require manual strength and precision to break a car window, which may not be feasible in urgent situations, and they often leave the user with a cumbersome tool.
Innovation Solution
A window breaking device with a generally orb shape and multiple point structures is designed to be thrown at a window, allowing it to break without the need for special tools or strength, and the device can be easily held and controlled in the user's hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional hammer-like or club-like tools are used to break windows, then the user can break the window, but the user must manually hold and control the tool requiring special strength and precision
Solution Approach 1:
Instead of the user holding and controlling the breaking tool (conventional approach), the invention inverts the approach by having the tool thrown at the window, eliminating the need for the user to maintain grip or control during the breaking action. The tool becomes a projectile that delivers the breaking force without requiring manual strength.
Solution Approach 2:
The invention extracts the breaking function from a manual tool and transforms it into a throwable projectile. By removing the handle and grip components typical of hammers or clubs, the device becomes a self-contained breaking element that can be thrown with minimal force, separating the breaking action from manual control requirements.
2Ease of operation
If conventional breaking tools are used, then the window can be broken, but the tools are cumbersome and require the user to maintain grip
Solution Approach 1:
The invention extracts only the essential breaking elements (points) from conventional breaking tools, removing handles, grips, and other cumbersome components. This leaves a simple, lightweight device that can be easily held and thrown, significantly reducing device complexity while maintaining breaking effectiveness.
Solution Approach 2:
The breaking surface is segmented into multiple points distributed across the device body. This segmentation allows the device to be compact and simple in overall structure while providing multiple contact points for effective glass breaking, reducing the need for complex single-point mechanisms.
3Adaptability or versatility
If multiple points are distributed on the device body, then the device can effectively break various types of glass, but the device requires precise manufacturing
Solution Approach 1:
The invention specifies parameter ranges rather than exact values: 6-12 points per device, 0.25-1.0 inch spacing, and 0.05-0.25 inch point height. These parameter ranges provide manufacturing flexibility while ensuring effective glass breaking across different glass types, reducing the need for ultra-precise manufacturing.
Solution Approach 2:
The multi-point design provides universal applicability for breaking different types of glass (side windows, windshields, various thicknesses). The distributed points ensure that regardless of the specific glass type or throwing angle, at least one point will effectively contact and break the glass, enhancing versatility without requiring precise customization for each application.
