Adjustable Vehicle Restraint System with Sliding Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seat belts and child restraint systems often fail to provide adequate protection due to improper fitting, lack of adjustability for varying user sizes and clothing, and incompatibility with different vehicle seat belt systems, leading to increased risk of injury during crashes.
Innovation Solution
A restraint system comprising multiple adjustable straps that can be secured to various vehicle seat belts, including lap and shoulder straps, with features like sliding security members and a supplemental back strap for enhanced anchoring, allowing for universal fit and use across different vehicle types and user sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If seat belts are designed for adult-sized occupants, then the restraint system is simplified, but it cannot accommodate children or varying user sizes
Solution Approach 1:
The restraint system incorporates adjustable shoulder straps with sliding adjusters that allow dynamic repositioning of the strap height and tension. This enables the same restraint system to adapt to users of different sizes (children and adults) while maintaining proper fit and safety effectiveness.
Solution Approach 2:
The restraint system is designed with universal compatibility features including multiple attachment points for different seat belt types (lap belts, shoulder belts, tether lines) and adjustable components that accommodate various user sizes. This multi-functionality allows one restraint system to serve multiple purposes across different vehicle types and age groups.
2Adaptability or versatility
If seat belts are non-adjustable, then the device complexity is reduced, but they cannot accommodate growth, weight changes, or different clothing layers
Solution Approach 1:
The restraint system features adjustable shoulder straps with sliding adjusters that enable dynamic reconfiguration as the user grows, gains or loses weight, or changes clothing layers. This dynamic adjustability ensures continuous proper fit throughout the user's development and varying conditions.
Solution Approach 2:
The restraint system includes pre-positioned adjustment mechanisms and multiple attachment points that anticipate future needs for reconfiguration. The design allows easy adjustment as the user grows or conditions change, eliminating the need for replacement and ensuring continuous safety.
3Adaptability or versatility
If the restraint system is highly adjustable, then it fits various users better, but it becomes more complex and harder to operate
Solution Approach 1:
The restraint system uses sliding adjusters on the shoulder straps that can be easily moved along the strap length and locked into position. This dynamic adjustment mechanism allows users to quickly and intuitively achieve proper fit without complex procedures, maintaining ease of operation while providing extensive adaptability.
Solution Approach 2:
The restraint system is designed with intuitive adjustment mechanisms that allow users to independently configure the system to their needs without assistance. The sliding adjusters and clear attachment points enable self-service adjustment, reducing operational complexity while maintaining high adaptability.
4Adaptability or versatility
If the restraint system is designed for specific vehicle types, then it can be optimized for that vehicle, but it cannot be used across multiple vehicle types
Solution Approach 1:
The restraint system incorporates universal attachment features including multiple anchor points that accommodate different seat belt configurations (lap belts, shoulder belts, tether lines). This multi-functionality enables the same restraint system to be safely used across multiple vehicle types including cars, buses, and airplanes without requiring vehicle-specific models.
Solution Approach 2:
The restraint system uses adjustable shoulder straps with sliding adjusters that can be reconfigured to accommodate different vehicle seat belt geometries and attachment points. This dynamic adjustability maintains proper fit and safety effectiveness across multiple vehicle types with varying seat belt configurations.
