Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single workpiece of stone is used and chiseled into desired shape, then the headstone has structural integrity and durability, but the manufacturing process is time-consuming and labor-intensive
Solution Approach 1:
The headstone is divided into multiple separate components including a base panel, frame members, and mounting assembly parts. These segmented components are manufactured independently using less time-consuming processes and then assembled together using the mounting assembly with T-nuts and bolts, thereby improving manufacturing productivity while managing assembly complexity through standardized connection mechanisms.
2Weight of moving object
If traditional stone headstones are used, then the headstone provides durability and permanence, but high cost is incurred in transporting and installing due to high weight
Solution Approach 1:
The headstone is segmented into multiple lighter components that can be transported separately and assembled on-site. The base panel, frame members, and mounting assembly are manufactured as separate pieces with reduced individual weights, lowering transportation costs while maintaining overall structural strength through the integrated frame design and secure mounting system.
Solution Approach 2:
The headstone assembly uses composite construction combining the base panel, frame members, and mounting assembly components. This composite structure achieves the required structural strength and durability through the combination of multiple materials and the interlocking mounting system, while reducing the overall weight compared to a solid stone monolith.
3Ease of manufacture
If chiseling and cutting processes are used on stone workpieces, then the desired headstone shape is achieved, but significant environmental impact and resource consumption occur
Solution Approach 1:
The manufacturing process is segmented into separate steps for different components (base panel, frame members, mounting assembly), allowing each to be manufactured using simpler, less environmentally damaging processes. This avoids the need for extensive chiseling and cutting of large stone blocks, thereby reducing environmental impact while maintaining manufacturing simplicity.
4Quantity of substance
If a modular assembly approach is used, then material and energy consumption is reduced, but the device complexity increases due to multiple components
Solution Approach 1:
The headstone is segmented into a base panel, frame members, and mounting assembly components, which reduces material consumption by eliminating excess stone and allowing precise manufacturing of each part. The complexity of multiple components is managed through standardized mounting interfaces using T-nuts and bolts, which simplify the assembly process and reduce the need for complex joining mechanisms.
Solution Approach 2:
The mounting assembly serves multiple functions: it connects the base panel to the surface, secures the frame members to the base panel, and provides a standardized interface for assembly. This multi-functional design reduces the need for separate specialized components, thereby reducing overall material consumption while managing device complexity through functional integration.
