Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workpiece carrier devices for stacking components, such as batteries and fuel cells, face challenges in maintaining stacking accuracy due to the need for frequent repositioning of storage locations, which increases the risk of inaccuracies during component placement.
Innovation Solution
A workpiece carrier device with a first fixing unit that allows side plates to be releasably fixed to supporting walls without tools, enabling the support plate to be moved step-by-step to maintain a stationary storage location, combined with guide mandrels and adjustable guide sections to ensure precise alignment and reduce tilting risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the support plate is moved to new storage heights after each component deposition, then components can be stacked in sequence, but stacking accuracy deteriorates due to the multitude of new positions
Solution Approach 1:
The support plate is made movable along the stacking direction through a drive mechanism, allowing it to be dynamically repositioned to create new deposit locations. This enables continuous stacking without manual intervention while maintaining consistent positioning accuracy through controlled movement.
Solution Approach 2:
The stacking process is segmented into discrete steps where the support plate moves to predetermined positions between component depositions. Each movement is controlled to reach specific intermediate positions, allowing systematic stacking while maintaining accuracy through position control.
2Stability of the object's composition
If side plates are permanently fixed to support walls, then structural stability is improved, but adaptability and ease of removal deteriorates
Solution Approach 1:
The side plates are designed with movable connections to the support walls through fixing units that allow tool-free attachment and detachment. This creates a dynamically adjustable structure that provides stability during operation but can be easily reconfigured or disassembled when needed.
Solution Approach 2:
The connection between side plates and support walls is segmented into modular fixing units that can be independently attached or detached. This allows the structure to be assembled and disassembled in sections without requiring tools, combining stability during use with ease of removal.
3Quantity of substance
If multiple new storage locations are created for stacked components, then stacking capacity increases, but positioning accuracy worsens due to increased movement requirements
Solution Approach 1:
The support plate's controlled movement along the stacking direction enables creation of multiple predetermined deposit locations. Each location is reached through controlled displacement, ensuring consistent positioning accuracy even as the number of stackable components increases.
Solution Approach 2:
Each deposit location is essentially a copied version of the starting position, displaced by a controlled amount along the stacking direction. This systematic copying of positions ensures uniformity and precision across multiple storage locations without requiring complex positioning for each new level.
