Adjustable Carriage Platform for Accurate Workpiece Levelling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting systems face inaccuracies when replacing cutting devices of different sizes, as the object to be cut may not be perfectly levelled, leading to potential inaccuracies in cutting.
Innovation Solution
A carriage system with a platform that can be adjusted vertically and equipped with a scissor mechanism and ratchet to ensure the object is levelled correctly relative to the cutting device, using a combination of pivotally mounted flaps and a drive mechanism for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cutting device is replaced with another cutting device of different size or structure, then the cutting device can be adapted to different cutting needs, but the object to be cut may not be perfectly levelled leading to cutting inaccuracies
Solution Approach 1:
The carriage platform is made adjustable in height through a scissor mechanism that can be extended or retracted, allowing the platform to dynamically change its vertical position. This enables the carriage to adapt to different cutting device heights while maintaining proper leveling, thus resolving the contradiction between adaptability and cutting precision
Solution Approach 2:
The height of the carriage platform is changed as a variable parameter through the scissor mechanism adjustment. By modifying the platform height parameter, the system can accommodate different cutting device sizes and structures while maintaining accurate cutting levels, thereby achieving both versatility and precision
2Manufacturing precision
If the carriage platform is made adjustable to ensure proper leveling, then cutting accuracy is improved, but the device complexity increases
Solution Approach 1:
The height adjustment function is segmented into a separate scissor mechanism module that is independent from the main carriage structure. This modular approach allows the adjustment mechanism to be added without fundamentally redesigning the entire carriage, thus improving precision while limiting the increase in overall complexity
Solution Approach 2:
The scissor mechanism provides a mechanically self-leveling function that automatically maintains the platform in a horizontal position regardless of height adjustment. This self-leveling capability eliminates the need for additional complex control systems or multiple adjustment mechanisms, achieving precision without excessive complexity

AI summary
A carriage comprising: a housing able to be slidably mounted on a track, a platform on which can rest an object to be cut by a cutting device mounted on the track, a stop able to stop the object relative to the cutting device while the object rests on the platform, wherein the platform is movable relative to the housing between a raised position and a lowered position wherein the platform is closer to the track than in the raised position, when the housing is slidably mounted on the track.
