Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wood processing systems with multi-articulated robots have complex structures and large exclusive spaces, making it difficult to fix processing objects of various shapes, such as flat plates, curved members, and increasing the system's cost and complexity.
Innovation Solution
A fixing device for multi-axis robots comprising a plurality of fixing units with a support member and a pressing device, where the support member includes a first frame and a second frame positioned vertically, allowing the pressing device to press the processing object against the first frame, enabling the fixation of various shapes by inserting them between the frames, and utilizing pneumatic or hydraulic pressure for the pressing device to simplify the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-articulated robot with movable saddles and tilt tables is used to process wood, then the robot can perform multiple processing operations, but the system structure becomes complicated and the exclusive space increases
Solution Approach 1:
The system divides the processing function into two independent parts: a fixed multi-articulated robot and separate movable saddles. Each saddle is an independent unit that can be moved to different positions along the guide rail, eliminating the need for complex integrated structures while maintaining processing versatility.
Solution Approach 2:
A guide rail serves as an intermediary structure that enables the saddles to move between different processing positions. This simple rail-saddle mechanism replaces complex integrated robot-saddle systems, reducing overall system complexity while preserving adaptability.
2Adaptability or versatility
If a multi-articulated robot with movable saddles and tilt tables is used to process wood, then the robot can perform multiple processing operations, but the exclusive space in the system increases
Solution Approach 1:
By separating the robot from the saddles and arranging saddles linearly along a guide rail, the system minimizes the footprint area. The linear arrangement allows saddles to share the same spatial zone at different positions, reducing the exclusive space required compared to having multiple fixed processing stations.
Solution Approach 2:
The guide rail extends the working space along one dimension (length), allowing multiple saddles to be arranged in a line rather than requiring two-dimensional or three-dimensional separation. This dimensional strategy reduces the area occupied by the system while maintaining the ability to process multiple workpieces.
3Reliability
If a vise and tilt table are used to attach processing objects, then the objects can be secured, but the shape of processable objects is restricted
Solution Approach 1:
The saddle is designed as a universal support structure that can accommodate various workpiece shapes through its flat upper surface and adjustable vise. The vise can clamp different geometries, and the flat surface provides stable support for diverse object forms, making the fixation system adaptable to plates, curved members, and other shapes without requiring specialized fixtures.
