Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual labor is used to move the utility table, then the table can be moved along the concrete surface, but the labor cost and effort increase significantly
Solution Approach 1:
The patent replaces the manual mechanical pushing system with an automated drive assembly that includes a motor, drive shaft, and drive wheels. This mechanical substitution eliminates the need for workers to manually move the utility table, thereby reducing labor effort while maintaining movement capability along the concrete surface.
Solution Approach 2:
The utility table is equipped with its own drive assembly that enables it to move autonomously without requiring external manual propulsion. The drive wheels, powered by the motor, allow the table to propel itself along the concrete surface, making the system self-sufficient in terms of movement.
2Productivity
If the utility table is moved long distances over concrete debris, then the finishing work can continue, but the labor cost increases
Solution Approach 1:
The manual mechanical system for moving the table over long distances is replaced with a motorized drive assembly. This substitution reduces the energy expenditure required from workers while enabling the table to traverse long distances over concrete debris, ensuring continuous finishing operations.
Solution Approach 2:
The drive assembly enables the utility table to move continuously along the concrete surface without interruption. The motorized propulsion system allows the table to cover long distances efficiently, maintaining the continuity of the concrete finishing work without requiring frequent stops or additional manual intervention.
3Ease of operation
If manual movement is used, then the table can be repositioned, but the time required for movement increases
Solution Approach 1:
The manual repositioning process is replaced with an automated motorized drive system. The drive wheels, controlled by the motor, enable rapid repositioning of the utility table along the concrete surface, significantly reducing the time required compared to manual pushing while maintaining full repositioning capability.
Solution Approach 2:
The utility table transitions from a static or manually moved structure to a dynamically controllable system. The motorized drive assembly allows the table to be quickly repositioned to different locations along the concrete surface, enabling adaptive and time-efficient repositioning based on finishing requirements.
