Freefall Loss Prevention Modules for Falling Object Deceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety solutions fail to effectively prevent loss and injury from objects in freefall, as they either require human intervention or are not designed to manage motion during freefall, leading to potential harm and damage.
Innovation Solution
A loss prevention device integrated into objects that detects freefall and deploys modules such as drag forces, trajectory diversion, or shock absorption mechanisms to manipulate the object's motion and prevent loss without human input, utilizing sensors, microcontrollers, and release mechanisms to activate loss prevention modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If safety nets are used to prevent falling objects from causing injury, then objects are prevented from reaching the ground, but the safety nets are immobile and cannot protect individuals not positioned below the net
Solution Approach 1:
The patent transforms the static safety net into a dynamic system by deploying inflatable cushions along the trajectory path. These cushions are positioned at multiple locations to create a moving protection zone that can cover larger areas and protect individuals positioned at different locations, not just directly below the fall point.
Solution Approach 2:
The invention extends protection from a single vertical plane (below the object) to a three-dimensional space by placing inflatable cushions at multiple heights and positions along the expected trajectory. This creates a volumetric protection zone that can intercept objects at various points in their fall path.
2Reliability
If behavioral guidelines such as the grab-and-twist method are used, then human intervention can prevent loss, but these methods can fail due to lack of training or human error during split-second windows
Solution Approach 1:
The system incorporates sensors that automatically detect freefall conditions and trigger the deployment of loss prevention modules without requiring human input. The device monitors its own state and autonomously activates protection mechanisms when freefall is detected, eliminating dependence on human reaction time or training.
Solution Approach 2:
The system uses sensors to continuously monitor the object's motion state and provides feedback to the control mechanism. When freefall conditions are detected through sensor data, the system automatically activates the loss prevention modules, creating a closed-loop control system that responds reliably to actual conditions.
3Reliability
If tethering tools or attachment points are used to prevent objects from dropping, then objects are secured during normal operation, but these solutions provide no remedy when the object is already in freefall
Solution Approach 1:
The loss prevention modules are pre-positioned and ready for deployment before freefall occurs. When freefall is detected, the system rapidly deploys these pre-positioned modules to intercept the object, providing immediate protection rather than attempting to secure an already-falling object.
Solution Approach 2:
The system transitions from a static tethering approach to a dynamic response system that activates loss prevention modules during freefall. The modules can deploy at various points along the trajectory based on real-time conditions, adapting to the object's motion state rather than relying on fixed attachment points.

AI summary
Disclosure are various embodiments of a loss prevention device responsive to freefall. The loss prevention device can be integrated into any object and incorporates physical, mechanical, and/or electrical modules configured to prevent the likelihood that dropping the object causes injury to persons or damage to structures in the vicinity. Such modules may constitute continuous or discrete, static or dynamic portions of the housing of the loss prevention device. Other modules may incorporate electromechanical components that allow for effective manipulation of the motion of the loss prevention device and the coupled object. The device can be configured to deploy said modules upon detecting freefall. In some cases, the device incorporate a release mechanism that facilitates said deployment.
