Modular Saw Disc Spacer Structure Reducing Material Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing spacer structure for saw disc assemblies in sawing machines results in significant material waste during manufacturing due to the cutting of elongated spacer means and hub devices in a single piece, complicating the manufacturing and repair processes.
Innovation Solution
A modular spacer structure design where the hub device is detachably or non-detachably arranged with the elongated spacer means, allowing for separate production and connection between saw discs, reducing material waste and simplifying assembly and repair by enabling the use of interchangeable parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the elongated spacer means and hub device are cut out in one single piece, then the structural integrity is improved, but the material waste becomes large
Solution Approach 1:
The spacer structure is divided into separate components: the elongated spacer means and the hub device are produced as separate pieces rather than one single piece. This segmentation allows for reduced material waste during manufacturing while maintaining structural integrity through the connection means that join these components together.
2Ease of manufacture
If the spacer structure is produced as one single piece, then the manufacturing process is simpler, but the repair process becomes more complicated
Solution Approach 1:
By dividing the spacer structure into separable components (elongated spacer means and hub device), the design enables easier repair through replacement of individual damaged parts rather than requiring replacement of the entire single-piece structure, while still maintaining manufacturing simplicity through standardized connection interfaces.
3Loss of substance
If the hub device and elongated spacer means are produced separately, then the material waste is reduced, but the assembly process becomes more complex
Solution Approach 1:
The connection means acts as an intermediary element that joins the separately produced hub device and elongated spacer means. This intermediary component simplifies the assembly process by providing standardized interfaces, making the combination of separate parts as straightforward as working with a single integrated piece.
