Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency medical services and military Prolonged Field Care (PFC) operations face challenges in delivering medical supplies and resupply to remote and hazardous locations efficiently, with existing systems lacking in safety and reliability for payload delivery.
Innovation Solution
A payload delivery device designed for manned and unmanned aerial vehicles, featuring a reinforced harness with a parachute system, capable of securely holding and protecting payloads during descent, incorporating a 5,000-pound tensile strength material and fireproof design, with an automatic deployment system to ensure safe landing and flotation devices for water landings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a payload delivery device is used to deliver medical supplies to remote locations, then the response time is reduced, but the safety and reliability of payload delivery is compromised
Solution Approach 1:
The patent applies beforehand cushioning by incorporating a parachute system that deploys prior to landing to cushion the payload's descent. The parachute creates aerodynamic drag to slow the falling payload, and the harness system is designed to absorb impact forces during touchdown, preventing damage to medical supplies before they reach the ground.
Solution Approach 2:
The patent uses composite materials in the harness construction, combining materials with different properties to achieve both strength and energy absorption. The harness incorporates high-tensile-strength materials for structural integrity alongside energy-absorbing materials that dissipate impact forces during landing, thereby protecting the payload while maintaining delivery speed.
2Device complexity
If a simple harness system is used for payload delivery, then the device complexity is reduced, but the payload protection from external forces is insufficient
Solution Approach 1:
The patent applies anti-weight principles by using the parachute system to counteract the gravitational force acting on the payload during descent. The aerodynamic drag generated by the parachute balances the weight of the payload, creating a controlled descent that reduces impact forces upon landing while maintaining a relatively simple harness structure.
Solution Approach 2:
The harness system incorporates dynamic elements that adapt to loading conditions. The harness uses flexible connections and energy-absorbing components that activate under impact loads, providing enhanced protection only when needed during landing while maintaining simplicity during normal transport and deployment phases.

Function Achieved in This Case
Enhances the survivability of patients and victims in emergency situations by securely delivering payloads, reducing injury and damage, and supporting operations like PFC and Tactical Combat Casualty Care, while accommodating various environments and planetary bodies.
Implementation Method 1
The present invention may include various connectors such as metal clasps. The metal clasps are rated for a breaking strength of 18 kilonewtons (kN) (4,046.56 pounds per clasp). Each clasp is also ANSI-approved. Furthermore, the incorporated parachute of the present invention may be deployed upon release of the harness from the aerial vehicle giving the vehicle time to clear the area and to allow the proper deployment of the parachute.
Implementation Method 2
a payload delivery device that protects the payload from any external forces resulting from the landing of the payload

AI summary
A payload delivery device is an apparatus designed to facilitate the delivery of emergency items to a target location via aerial vehicles. The apparatus includes a base strap, a plurality of holder straps, and a plurality of cargo straps. The base strap serves as the central structure of the apparatus that supports the plurality of holder straps and the plurality of cargo straps. The plurality of holder straps includes several straps designed to retain a parachute and the devices necessary to facilitate the deployment of the parachute. The plurality of holder straps is also designed to facilitate the operation of the parachute while securing the parachute to the base strap. The plurality of cargo straps include several straps that secure the payload to the apparatus. The plurality of cargo straps can also be arranged to accommodate the shape and size of the payload to be delivered using the apparatus.
