Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If hydraulic hoses are replaced individually without pre-arrangement, then the replacement process becomes simple and flexible, but the time required for replacement increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-arranging multiple hydraulic hoses in bundles on support frames before transport to the work site. The hoses are pre-positioned and organized in the carrier according to the replacement sequence, so that when a hose needs replacement, the entire bundle is already prepared and can be quickly installed without time-consuming on-site arrangement.
Solution Approach 2:
The patent segments the hydraulic hose replacement system into modular bundles, each containing specific hoses arranged on individual support frames. These segmented bundles are organized in a carrier according to replacement priority, allowing systematic and efficient replacement by processing one segment at a time rather than handling all hoses individually.
2Productivity
If hydraulic hoses are transported separately without organization, then the transport is flexible, but the installation process becomes time-consuming and complex
Solution Approach 1:
The support frames are used to pre-arrange and pre-position the hydraulic hoses in their correct spatial relationships before transport. This preliminary arrangement ensures that when the bundles are delivered to the work site, the hoses are already in the correct configuration for installation, eliminating the need for time-consuming on-site arrangement and improving both productivity and ease of operation.
Solution Approach 2:
The patent merges multiple hydraulic hoses into organized bundles on common support frames. By combining related hoses into integrated units that maintain their spatial relationships, the system improves handling efficiency during transport and installation, making the replacement process more productive and easier to execute.
3Shape
If multiple hoses are bundled together without support structure, then the kit size is reduced, but the hoses lose their correct spatial shape and positioning
Solution Approach 1:
The support frames act as rigid structural shells that maintain the three-dimensional spatial arrangement of the hydraulic hoses within the bundles. These frames provide the necessary geometric support to preserve the correct shape and positioning of hoses while allowing the entire assembly to be compactly organized in the carrier, balancing shape preservation with space efficiency.
