Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printer systems lack an efficient and versatile mechanism for collecting printed products, particularly in transitioning between flat surface and bag configurations, which affects the ease and stability of handling single or multiple sheets post-printing.
Innovation Solution
A convertible printed product collecting assembly featuring a tensioning and locking mechanism for the collecting fabric, allowing it to be rolled, unreled, and tensioned to form either a flat surface or a bag, with tiltable and telescopic supporting legs and stabilizing brackets for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the collecting fabric is kept in a fixed flat configuration, then it provides a stable surface for collecting printed products, but it cannot adapt to different collection needs such as bag configuration for multiple sheets
Solution Approach 1:
The collecting fabric is transformed from a static fixed configuration to a dynamic reconfigurable system. The fabric can be rolled around a bearing rod and unrolled as needed, allowing transition between flat surface configuration and bag configuration. This dynamic mechanism enables the fabric to adapt to different collection needs while maintaining stability during each configured state through the tensioning and locking mechanism.
Solution Approach 2:
The collecting fabric is rolled around the fabric bearing rod when not in use or when transitioning between configurations. This nesting approach allows the fabric to be compactly stored on the rod while maintaining easy accessibility for deployment. The rolled fabric on the rod serves as a compact reservoir that can be quickly unrolled to provide the needed collecting surface or bag configuration.
2Adaptability or versatility
If the collecting fabric is made loose and flexible for easy configuration changes, then it can form both flat and bag configurations, but it loses tension and stability required for proper printed product collection
Solution Approach 1:
The tensioning and locking mechanism operates automatically through user interaction without requiring external tools or complex adjustment procedures. When the fabric needs tensioning, the user simply activates the locking mechanism which automatically tensions the fabric to the appropriate level. The mechanism self-regulates to maintain proper tension during both flat and bag configurations, ensuring reliability without sacrificing flexibility.
Solution Approach 2:
The tensioning and locking mechanism allows dynamic adjustment of the fabric's tension parameter. The mechanism can tension the fabric to different degrees depending on the configuration mode (flat surface vs. bag configuration). This parameter control ensures that the fabric maintains adequate tension for reliable printed product collection while still allowing the flexibility needed for configuration changes between different modes.
3Ease of manufacture
If a simple fabric support structure is used, then the assembly is easy to manufacture and install, but it cannot provide adequate positioning and stability for the fabric in various configurations
Solution Approach 1:
The support structure is divided into modular functional components: the fabric bearing rod for fabric support and rolling, the tensioning and locking mechanism for tension control, and the supporting legs with stabilizing brackets for positioning. Each segment performs a specific function and can be independently manufactured and assembled. This segmentation provides adequate positioning and stability while maintaining ease of manufacture through standardized modular components.
Solution Approach 2:
The fabric bearing rod serves as an intermediary element between the fabric and the supporting structure. It provides a simple yet effective means of supporting the fabric while allowing it to be rolled and unrolled. The rod mediates between the need for fabric flexibility and the need for structural support, enabling configuration changes without requiring complex support mechanisms.

AI summary
A convertible printed product collecting assembly (10) includes a collecting fabric (11) rolled on a rotatable fabric bearing rod. Supporting legs (13) have a lower end tiltably connected to a printer (18) and are tillable in the collecting fabric's longitudinal direction. A tensioning and locking mechanism (15, 16) is arranged to release or to lock the fabric bearing rod to rotate. Stabilizing brackets (14) secure the supporting legs (13) in at least one tilting angle. The tensioning and locking mechanism (15, 16) is operable to tension and to hold the collecting fabric (11) in a flat, tensioned shape when in the locking state so as to provide a receiving desk for the printed product. Further, the collecting fabric (11) forms a collecting bag when unreeled from the fabric bearing rod.
