Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing planar transport devices with electromagnetically coupled platforms face complexity in payload removal due to the need for energy supply and line systems for suction elements, which increases complexity and limits location-independent removal, especially when handling payloads of different dimensions or geometries.
Innovation Solution
Incorporating a movable inertia element aligned with the platform's payload space, allowing kinetic energy transfer during deceleration to facilitate payload removal without additional actuators, enabling location-independent removal of various payloads by leveraging the platform's mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a suction element with energy supply and line system is used for payload removal, then payload removal capability is improved, but device complexity increases
Solution Approach 1:
The invention extracts the payload removal function from complex suction devices with energy supplies and line systems, isolating only the essential mechanical element (inertia element) needed for payload ejection. This removes the harmful complexity while preserving the useful payload removal capability.
Solution Approach 2:
The inertia element utilizes the platform's own motion and deceleration to generate the force needed for payload ejection. The platform's kinetic energy during deceleration automatically drives the inertia element to eject the payload, eliminating the need for separate energy supplies and control systems.
2Device complexity
If a stationary suction device is used for payload removal, then line system complexity is reduced, but location-independent removal is lost
Solution Approach 1:
The inertia element is made movable relative to the platform rather than stationary, allowing it to dynamically respond to the platform's motion and deceleration at any location on the drive surface. This dynamic configuration enables location-independent payload removal while maintaining simplicity.
Solution Approach 2:
The platform's own motion serves as the actuation mechanism for the inertia element at any location. The deceleration of the platform automatically generates the force needed to eject the payload, eliminating the need for external line systems while maintaining location independence.
3Reliability
If a suction element is tailored to specific payload shape and size, then payload holding capability is improved, but adaptability to different payloads decreases
Solution Approach 1:
Instead of adapting the ejection mechanism to each payload type, the invention inverts the approach by using a universal inertia element that ejects payloads through a common mechanism (platform deceleration). The payload's own mass and the platform's motion determine the ejection effectiveness, eliminating the need for payload-specific tailoring.
Solution Approach 2:
The inertia element serves as a universal payload ejection mechanism that works with payloads of different shapes, sizes, and materials. The same basic mechanism (inertia-driven ejection during platform deceleration) handles all payload types, providing multi-functionality without requiring customization.
