Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If robot assisted technologies are used to move heavy objects and perform automated storage and retrieval, then worker safety is improved and order fulfillment efficiency is increased, but stability issues arise due to tip-overs, navigation problems, and inaccurate item selection
Solution Approach 1:
The patent applies beforehand cushioning by incorporating a suspension system with shock-absorbing elements before stability issues occur. The suspension system includes springs and dampers positioned at the mobile base that proactively absorb shocks and vibrations during operation, preventing tip-overs and navigation problems before they happen. This allows the robot to operate reliably among human workers by cushioning against potential instability triggers.
2Productivity
If automated storage and retrieval systems are implemented, then workers can remain at workstations for packing orders, but the system complexity increases with mobile base, suspension system, robotic arm, and storage component integration
Solution Approach 1:
The patent applies universality by designing the mobile base with a suspension system that serves multiple functions: it provides shock absorption for stability, enables mobile movement for navigation, and supports the storage component and robotic arm. This multi-functional design reduces overall system complexity by consolidating functions into integrated components rather than separate systems.
Solution Approach 2:
The patent applies segmentation by dividing the automated storage and retrieval system into modular components: a mobile base with suspension system, a storage component, and a robotic arm component. Each module can be independently designed, tested, and maintained, reducing the complexity of the overall system while maintaining high productivity through coordinated operation of these segmented parts.
