Perforated Plate Press Base for Non-Rectangular Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing woodworking pressing devices are limited in their ability to effectively press both large-sized and small, non-rectangular objects such as triangular or polygonal shapes, as they lack the necessary adaptability and flexibility to accommodate these diverse forms.
Innovation Solution
A pressing device featuring a flat, frame-shaped base frame with a perforated plate integrated as a rear wall, allowing for adjustable support shoes and arm-like clamping rails, and pressure application devices that can be rotated and positioned within the grid of openings to accommodate objects of various sizes and shapes, including triangular or polygonal ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flat frame-shaped base frame with adjustable support shoes is used, then large-sized objects can be pressed effectively, but small-sized and non-rectangular objects cannot be pressed
Solution Approach 1:
The base frame is segmented into a modular structure with a perforated plate containing multiple openings. Pressure application devices can be selectively attached to different openings based on the object size and shape, allowing the same base structure to handle various pressing tasks through configuration changes rather than requiring multiple specialized devices
Solution Approach 2:
The pressing device achieves multi-functionality by allowing different pressure application devices to be attached to the same base frame structure. The perforated plate with multiple openings serves as a universal mounting interface, enabling the device to press rectangular, triangular, polygonal, and other shaped objects using the same fundamental structure with different attachments
2Adaptability or versatility
If fixed pressure application points are used, then pressing of rectangular objects is simple, but pressing of triangular or polygonal objects is not possible
Solution Approach 1:
The pressure application devices are made dynamically positionable through the perforated plate structure. Instead of fixed mounting points, the openings allow devices to be attached at various locations and orientations, enabling adaptation to triangular, polygonal, and other non-rectangular shapes while maintaining ease of operation through standardized attachment mechanisms

AI summary
The pressing device (2) comprises: - a flat, frame-shaped base (4, 10, 12) which forms a lateral, optionally slightly inclined relative to the vertical, contact plane for an object to be pressed, and - short, clamping jaw-like, adjustable support shoes (14) or elongated, arm-like clamping and support rails (16) attached to the base (4, 10) and arranged above the contact plane, on which the object to be pressed is to be arranged and between which the object to be pressed is to be pressed, - a pressure-acting device acting on the upper support shoes (14) or the lower support rail (16), characterized in that the flat, frame-shaped base (4, 10, 12) has a perforated plate.
