Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple workers (three to five workers) manually lift the heating pipes, then the supply lines can be lifted, but worker health deteriorates (back problems) and personnel costs increase
Solution Approach 1:
The patent replaces manual mechanical lifting with a hydraulic lifting system. The hydraulic unit (comprising hydraulic pump, hydraulic cylinder, and piston) converts hydraulic energy into mechanical lifting force, allowing a single operator to lift heavy supply lines that previously required multiple workers. This substitution eliminates the harmful physical strain on workers while maintaining the lifting function.
Solution Approach 2:
The patent employs a hydraulic system to provide the lifting force. The hydraulic unit uses fluid pressure (hydraulic fluid) to generate the necessary force for lifting heavy supply lines. The hydraulic pump generates pressure, which acts on the piston within the hydraulic cylinder, producing the lifting force. This hydraulic mechanism replaces the need for multiple workers to manually lift the heavy pipes.
2Productivity
If multiple workers (three to five workers) manually lift the heating pipes, then the supply lines can be lifted, but cleaning costs increase due to increased personnel requirements
Solution Approach 1:
The patent replaces manual mechanical lifting with a hydraulic lifting system. The hydraulic unit (comprising hydraulic pump, hydraulic cylinder, and piston) converts hydraulic energy into mechanical lifting force, allowing a single operator to lift heavy supply lines that previously required multiple workers. This substitution eliminates the harmful physical strain on workers while maintaining the lifting function.
Solution Approach 2:
The hydraulic lifting device is designed to be operated by a single person who controls the hydraulic pump and directs the lifting operation. The system serves itself by using the hydraulic fluid pressure generated by the pump to automatically lift the supply lines, eliminating the need for coordinated manual effort by multiple workers. This self-service capability reduces personnel requirements while maintaining cleaning productivity.
3Force
If heavy supply lines (80kg to 100kg) are lifted manually, then the supply lines can be moved, but physical strain on workers increases
Solution Approach 1:
The patent employs a hydraulic system to provide the lifting force. The hydraulic unit uses fluid pressure (hydraulic fluid) to generate the necessary force for lifting heavy supply lines. The hydraulic pump generates pressure, which acts on the piston within the hydraulic cylinder, producing the lifting force. This hydraulic mechanism replaces the need for multiple workers to manually lift the heavy pipes.
Solution Approach 2:
The hydraulic system effectively counteracts the weight of the heavy supply lines (80kg to 100kg) by generating an equal and opposite lifting force through hydraulic pressure. The piston, acted upon by hydraulic fluid pressure, creates a counterbalancing force that lifts the heavy load, eliminating the physical strain that would otherwise be experienced by workers attempting to lift the same weight manually.
