Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current restraining systems for vehicles are inefficient and lack flexibility, failing to effectively prevent motion-related injuries during travel.
Innovation Solution
A locking harness apparatus comprising adjustable straps with a retainer apparatus and a braking mechanism, including a spring assembly and compression mechanism, which applies resistance to hold the retainer portions in a stationary position, and an optional sensor and alarm system to detect movement and alert users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional restraining system is used, then the structure is simple, but the flexibility and effectiveness in preventing motion-related injuries is insufficient
Solution Approach 1:
The restraining system is divided into multiple independent components: adjustable harness straps with sliding adjusters, retainer portions that can be positioned independently, and braking mechanisms that can be engaged separately. This segmentation allows each component to be optimized for its specific function while providing overall system flexibility.
Solution Approach 2:
The system incorporates dynamic elements including sliding adjusters that allow continuous position adjustment along the straps, movable retainer portions that can be repositioned as needed, and braking mechanisms that can be engaged or disengaged to change the restraint state. This dynamic capability enables the system to adapt to different usage scenarios.
2Reliability
If a locking mechanism with spring assembly and braking device is added, then the effectiveness in preventing motion-related injuries is improved, but the device complexity increases
Solution Approach 1:
The braking mechanism incorporates a spring assembly that automatically engages the braking device when the retainer portion is pulled taut, providing self-activating restraint without requiring additional control inputs. The compression mechanism automatically compresses the spring when the retainer is released, preparing it for the next engagement cycle.
Solution Approach 2:
The spring assembly acts as an intermediary energy storage element between the user's pulling action and the braking mechanism. It accumulates energy during strap adjustment and releases it to activate the braking device, providing a smooth and reliable engagement without requiring direct mechanical coupling between all components.
3Reliability
If sensor and alarm systems are integrated, then the safety monitoring capability is enhanced, but the device complexity and cost increase
Solution Approach 1:
The sensor detects the position and movement state of the retainer portions and provides feedback signals to the control system. When abnormal movement or release is detected, the alarm system provides immediate warning to the user, creating a closed-loop safety monitoring system that continuously verifies proper restraint engagement.
