Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart distribution vehicles face challenges in stably fixing pallets with various shapes and materials due to the lack of a universal fixing method, which can lead to safety accidents.
Innovation Solution
The smart distribution vehicle is equipped with a fork arm, a fork, an electromagnet mounted on the fork arm, and a control system that determines the magnetic properties of the pallet to stabilize its fixation using an electromagnet for metal pallets and a clamp for non-metal pallets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple mechanical fixing method is used, then the device complexity is reduced, but the reliability of pallet fixation deteriorates due to inability to handle various shapes and materials
Solution Approach 1:
The patent implements a dynamic fixing system that adapts its behavior based on detected pallet properties. The control unit dynamically switches between electromagnetic fixation (for metal pallets) and mechanical clamp fixation (for non-metal pallets) based on real-time detection results, allowing the system to optimize fixation reliability for each pallet type without requiring a completely complex fixed-system design
Solution Approach 2:
The system changes the fixation parameter (method) based on the detected material property of the pallet. By detecting whether the pallet is metallic or non-metallic and then changing the fixation approach accordingly, the system achieves high reliability across different pallet types while managing complexity through parameter adaptation rather than structural complexity
2Adaptability or versatility
If a universal fixing method is implemented, then the adaptability to various pallet types is improved, but the device complexity increases
Solution Approach 1:
The patent creates a universal fixing system where a single electromagnet can handle both metal and non-metal pallets by switching between electromagnetic attraction mode (for metal) and mechanical clamp mode (for non-metal). This multi-functionality approach allows one system to adapt to various pallet types without requiring separate specialized systems for each material type
Solution Approach 2:
The system uses a detection unit to sense the pallet's material properties and provides feedback to the control unit, which then adjusts the fixation method accordingly. This feedback mechanism enables the system to adapt to different pallet types automatically, improving versatility while managing complexity through intelligent control rather than redundant hardware
3Reliability
If electromagnetic fixation is used for all pallets, then the fixation speed is improved, but the reliability deteriorates for non-metallic pallets
Solution Approach 1:
The system dynamically adjusts the fixation method based on pallet material detection. For metal pallets, it uses fast electromagnetic attraction; for non-metallic pallets, it switches to mechanical clamping. This dynamic adaptation ensures that each pallet type receives the most appropriate fixation method, maintaining both high reliability and efficient fixation speed without forcing a single method on all pallet types
