Solution Overview
Problem
Current testing systems for electronic devices, such as robotic arms, often misposition electronic devices during delivery due to multiple degrees of freedom, leading to increased maintenance costs and potential device damage.
Innovation Solution
A conveyor arrangement with a plate system that elevates and lowers through openings, allowing precise movement and positioning of electronic devices within a drawer-type testing system, reducing degrees of freedom and eliminating the need for expensive robotic arms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a robotic arm is used to deliver electronic devices to testing areas, then the device can be moved to different locations, but the device may be positioned incorrectly due to multiple degrees of freedom
Solution Approach 1:
The robotic arm is segmented into multiple modular components (base unit, extension units, testing units) that can be independently positioned and controlled. Each segment has reduced degrees of freedom compared to a traditional robotic arm, allowing precise positioning while maintaining delivery capability to multiple testing areas.
Solution Approach 2:
The system dynamically adjusts the configuration of extension units between the base and testing units, allowing the structure to adapt to different device sizes and testing locations while maintaining stable, precise positioning through controlled mechanical connections rather than multiple independent degrees of freedom.
2Adaptability or versatility
If a robotic arm with multiple degrees of freedom is used, then the device can be delivered to various testing areas, but maintenance work and costs increase
Solution Approach 1:
The system is divided into independent modular units (base unit, extension units, testing units) that can be maintained separately. Each module has simplified mechanics with fewer degrees of freedom, reducing maintenance complexity while the modular architecture allows easy replacement or repair of individual components without affecting the entire system.
Solution Approach 2:
Extension units serve multiple functions: they extend the reach to different testing areas, provide structural support, and enable positioning adjustments. This multi-functionality reduces the need for multiple specialized components, simplifying maintenance while maintaining versatility.
3Extent of automation
If a robotic arm is used for device delivery, then automation is achieved, but the system complexity and cost increase
Solution Approach 1:
The automated delivery system is segmented into standardized modular units with simple, repeatable mechanical connections. Each unit has reduced degrees of freedom compared to a traditional robotic arm, simplifying the control system while maintaining automation capability through coordinated movement of multiple simple modules rather than one complex robotic arm.
