Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned vehicles lack the ability to dynamically change form or split into sub-drones in response to environmental conditions or task requirements, limiting their versatility and efficiency in complex or changing scenarios.
Innovation Solution
The development of polymorphic unmanned vehicles (UVs) that can morph based on sensed conditions, utilizing programmable polymers, electromagnetic latches, and servo mechanisms to change shape, split into sub-drones, or reconfigure sensors, allowing for adaptive task execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If unmanned vehicles use fixed form and configuration, then device complexity is reduced, but adaptability to different conditions and tasks deteriorates
Solution Approach 1:
The unmanned vehicle is divided into multiple detachable sub-drones that can separate from the main body. Each sub-drone can operate independently or remain attached to the mothership, allowing the system to adapt between single-vehicle and multi-vehicle configurations based on task requirements, thereby improving adaptability without permanently increasing device complexity.
Solution Approach 2:
The unmanned vehicle employs dynamic reconfiguration capabilities where the form and configuration can change during operation. The vehicle can transition between different morphologies (e.g., attached vs. detached sub-drones, different sensor orientations) in response to sensed environmental conditions, enabling adaptability while maintaining a relatively simple base structure.
2Ease of operation
If unmanned vehicles maintain constant configuration, then ease of operation is improved, but ability to navigate constrained spaces deteriorates
Solution Approach 1:
The vehicle can detach into smaller sub-drones that are capable of navigating constrained spaces that would be inaccessible to the full-sized mothership. This segmentation allows the system to operate easily in both open environments (as a unified vehicle) and constrained environments (as smaller independent units).
Solution Approach 2:
The sub-drones can nest within or attach to the mothership structure, allowing compact storage and simplified operation when the full capability is not needed. The nested configuration reduces the operational complexity while preserving the ability to deploy smaller units for constrained space navigation.
3Reliability
If unmanned vehicles do not change form, then loss of time for reconfiguration is avoided, but ability to avoid damage from environmental conditions deteriorates
Solution Approach 1:
The unmanned vehicle uses sensors to detect environmental conditions in advance and proactively reconfigures its form before damage can occur. For example, it can detach sub-drones or change orientation preemptively when hazardous conditions are sensed, reducing the time available for damage avoidance while maintaining high reliability through advance detection and action.
