Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy-duty industrial unmanned aerial vehicles require disassembly of the entire body for energy part replacement, which is tedious and time-consuming due to the need for additional disassembling tools.
Innovation Solution
A quick disassembling structure featuring a first and second module connected via a guide and positioning piece, with detachable connection through threaded, interference, hook, or pin connections, allowing for simple and efficient assembly and disassembly, enabling detachable connection and circuit conduction between the body and energy-load module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the energy part is integrated with the body, then the structural strength is improved, but the replacement process becomes tedious and time-consuming
Solution Approach 1:
The integrated body-energy part structure is segmented into separable modules: the body (first module) and the energy-load module (second module). The quick disassembling structure includes a first connecting piece on the body and a second connecting piece on the energy-load module, allowing the energy part to be replaced independently without disassembling the entire body, thus reducing replacement time while maintaining structural integrity during operation
Solution Approach 2:
The connection between the body and energy-load module transitions from a fixed integrated state to a dynamic state where it can be quickly assembled and disassembled. The quick disassembling structure enables the system to switch between integrated operation mode and separated replacement mode, optimizing both structural strength during operation and replacement efficiency during maintenance
2Reliability
If additional disassembling tools are used for replacement, then the connection reliability is improved, but the operation complexity increases
Solution Approach 1:
The quick disassembling structure is designed to be self-sufficient for connection and disconnection operations. The first connecting piece and second connecting piece are configured to engage and disengage directly without requiring external disassembling tools, thereby maintaining connection reliability through precise fitting while significantly simplifying the replacement operation
Solution Approach 2:
The connecting pieces are designed with multi-functional characteristics, serving both as structural connection elements and as self-contained fastening mechanisms. The threaded connection and tapered design provide both secure attachment and easy manual operation, eliminating the need for specialized tools
3Ease of operation
If the body is disassembled for energy part replacement, then the replacement accessibility is improved, but the productivity decreases
Solution Approach 1:
The system is segmented such that the energy-load module is an independent replaceable unit with its own connecting piece. This segmentation allows direct access to the energy part through the quick disassembling interface without requiring disassembly of the entire body structure, thereby maintaining accessibility while preserving overall productivity
Solution Approach 2:
The energy-load module is pre-configured with the second connecting piece and mounting structures before installation. This preliminary preparation allows for quick alignment and attachment to the body's first connecting piece, eliminating the need for time-consuming on-site assembly or body disassembly operations
