Arresting Net Vehicle Window Structure for Rollover Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with fixed windows, passengers are at risk of being thrown out during rollovers due to the lack of effective window protection, as airbags are not fixed and may deflate, and the installation of airbags in multiple windows is costly and complex.
Innovation Solution
A vehicle window structure comprising a fixing frame, an arresting net made of interlaced plastic ropes, and a light-permeable unit, where the arresting net is directly fixed to the frame to prevent ejection, providing a soft cushioning effect and maintaining functionality even if the light-permeable unit is damaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If airbags are installed in all windows to protect passengers during rollover, then passenger safety is improved, but installation cost and device complexity increase significantly
Solution Approach 1:
The patent extracts the essential safety function from complex airbag systems and implements it through a simpler arresting net structure made of plastic ropes that can be directly fixed to window frames, eliminating the need for inflators, sensors, and complex control systems while maintaining the core function of preventing passenger ejection
Solution Approach 2:
The patent employs inexpensive plastic ropes and simple fixing portions that can be easily replaced if needed, substituting expensive airbag systems with a cost-effective solution that achieves the same safety outcome through a disposable or replaceable net structure
2Reliability
If airbags are installed in all windows to protect passengers during rollover, then passenger safety is improved, but overall installation cost increases
Solution Approach 1:
The patent uses inexpensive plastic ropes and simple fixing portions that are much cheaper than airbag systems, making it economically feasible to install safety protection in all windows of vehicles with multiple windows without significantly increasing overall cost
3Reliability
If traditional airbags are used in fixed windows, then passenger protection is provided, but the airbag takes more time to be inflated and may deflate slowly over time
Solution Approach 1:
The patent pre-positions the arresting net structure in a ready-to-use state, fixed to the window frame with plastic ropes that are immediately functional, eliminating the inflation delay inherent in airbag systems and providing instant protection upon rollover occurrence
Solution Approach 2:
The patent removes the inflation mechanism and gas storage components from the safety system, using only the passive arresting net structure that provides immediate protection without the time delay associated with airbag inflation processes

AI summary
A vehicle window structure for preventing a person from being thrown out, applied to a vehicle, includes a fixing frame. An inner frame surface of the fixing frame is provided with a plurality of fixing portions spaced apart from each other. An arresting net includes at least one plastic rope fixedly connected to the fixing portions in an interlaced manner. The fixing frame is provided with a light-permeable unit that is mounted and fixed within the inner frame surface and covers the arresting net. When the vehicle has an accidental rollover unfortunately, even if the light-permeable unit is damaged or the fixing frame is deformed during the overturning of the vehicle, the arresting net is still able to arrest the user effectively because the arresting net is directly fixed to the fixing frame, thereby preventing the user from being thrown out of the vehicle.
