Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The removal and attachment of build plates from and to robotic arms in three-dimensional printing systems are slow and can lead to positioning difficulties, affecting printing speed and efficiency.
Innovation Solution
A mounting rack and tool system featuring a support member with recesses and magnets, along with spring ball plungers, to securely hold and position printing tools, allowing for efficient transfer and alignment of build plates without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If build plates are manually removed and attached from robotic arms, then the system can handle build plate changes, but the printing speed decreases and positioning accuracy deteriorates
Solution Approach 1:
The mounting rack with magnets and spring ball plungers enables the build plate to be automatically retained and positioned without human intervention. The robotic arm can directly pick up and place build plates onto the self-retaining rack, eliminating manual handling steps and reducing exchange time while maintaining printing speed.
2Ease of operation
If build plates are manually positioned at the mounting rack, then flexibility in handling is maintained, but positioning precision deteriorates making subsequent picking difficult
Solution Approach 1:
The manual mechanical positioning process is replaced with a magnetic field-based retention system combined with spring ball plunger mechanical guidance. The magnets provide automatic alignment and holding force, while the spring ball plungers ensure precise positional registration, eliminating positioning errors without requiring manual dexterity.
3Device complexity
If simple mounting racks without retention mechanisms are used, then the structure remains simple, but the build plates cannot be securely held during automated handling
Solution Approach 1:
Magnetic fields serve as an intermediary force between the mounting rack and build plate, providing secure retention without direct mechanical contact. The magnets embedded in the mounting rack create an invisible holding field that reliably secures build plates during automated robotic handling while keeping the rack structure relatively simple.
