Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional presses for multisided cladding of parts with sheet material face high production costs and vulnerability due to manual setup and maintenance requirements, especially with articulated pins, which are prone to breakage and require frequent maintenance.
Innovation Solution
A press design featuring a part supporting tray with a grid of holes and variable-length actuation pins, where the pins can adjust between activation and deactivation positions using elastic means and actuators, allowing automated setup and reducing manual intervention, while being protected from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual arrangement of pins is used to create supporting shapes, then flexibility in adapting to different part shapes is improved, but setup time and labor costs increase significantly
Solution Approach 1:
The system automatically detects part contours and activates only the necessary pins without manual intervention. The detection means scan the part shape and the activation means automatically position pins based on detected features, making the system self-configuring for different part geometries.
Solution Approach 2:
Manual mechanical arrangement of pins is replaced by an automated system combining detection means (scanning devices) and activation means (controlled pin positioning mechanisms). This substitution eliminates manual labor while maintaining adaptability to various part shapes.
2Adaptability or versatility
If articulated pins are used to provide variable length support, then adaptability to different part geometries is improved, but reliability decreases due to pin breakage and maintenance requirements
Solution Approach 1:
The pin system transitions from static fixed-length pins to dynamic variable-length pins that can be activated or deactivated based on part geometry. This dynamic adjustment allows the same pin to serve multiple support positions, reducing the total number of pins needed while maintaining geometric adaptability.
Solution Approach 2:
Each pin is designed to perform multiple functions by being activatable at different positions and lengths. A single pin can serve as a support point for various part shapes by adjusting its activation state, eliminating the need for multiple specialized pins and reducing overall system complexity.
3Adaptability or versatility
If multiple supporting shapes are provided for different part batches, then adaptability to various part shapes is improved, but production costs increase due to manufacturing and management overhead
Solution Approach 1:
The supporting shape system is segmented into individual controllable pins rather than requiring complete pre-fabricated supporting structures. Each pin can be independently activated or deactivated, allowing the system to create only the specific support geometry needed for each part batch, reducing unnecessary components.
Solution Approach 2:
The system performs preliminary detection of part shapes before pin activation. By scanning and detecting part geometries in advance, the system pre-determines which pins need to be activated, optimizing the supporting configuration before the actual cladding process begins and avoiding unnecessary setup steps.
4Ease of operation
If pins protrude below the part supporting tray to raise parts, then support effectiveness is improved, but vulnerability to damage increases during insertion and extraction
Solution Approach 1:
The pins transition from a static protruding state to a dynamic state where they can be retracted or deactivated when not in use. This dynamic behavior protects pins from damage during tray insertion and extraction by minimizing their exposure to mechanical impacts while maintaining support effectiveness during the cladding operation.

AI summary
A press comprising an upper pressing surface (1) and a lower pressing surface (2), which face each other, and a part supporting tray (3) provided with a bottom (4) which forms a substantially horizontal supporting surface for the parts (5) to be clad and can be rested on the lower pressing surface (2). The bottom (4) of the part supporting tray (3) is crossed by a plurality of holes (6) which have a substantially vertical axis and are arranged in a grid, and the lower pressing surface (2) is provided with a plurality of actuation pins (7) which have a substantially vertical axis (7a) and are arranged so as to correspond to the holes (6) of the part supporting tray (3). The part supporting tray (3) can be arranged so that the axes of its holes (6) are aligned with the axes of the actuation pins (7) and the actuation pins have a vertical length which is variable as a function of the contour of the parts (5) arranged on the part supporting tray (3) in order to be inserted, in their maximum-length condition, through the holes (6), producing support regions which are raised, with respect to a substantially horizontal supporting surface formed by the part supporting tray (3), and make contact with the lower face of the parts (5) in regions which are spaced from the perimetric edge of the parts (5), or so as to not create, in their minimum-length condition, support regions which are raised with respect to the supporting surface formed by the part supporting tray (3).
