Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If natural ventilation is used to dissipate heat from the control box, then the structure is simple, but the heat dissipation efficiency is poor
Solution Approach 1:
The patent replaces natural convection (passive thermal field) with forced convection using a fan-driven air circulation system. The fan actively moves air through the control box, significantly enhancing heat dissipation efficiency compared to relying solely on natural ventilation.
Solution Approach 2:
The patent changes the airflow parameter from passive natural convection to active forced convection by introducing a fan. This parameter change increases the air velocity and heat transfer coefficient, thereby improving heat dissipation efficiency while managing control box temperature.
2Force
If the hydraulic press is used to press mixed fiber felt, then the pressing function is achieved, but the telescopic resistance increases after long-term use due to material friction
Solution Approach 1:
The patent introduces lubricating oil as an intermediary substance between the moving parts of the hydraulic cylinder. This lubricating film reduces direct metal-to-metal contact and material friction, thereby decreasing telescopic resistance and maintaining reliable hydraulic cylinder performance over extended use.
Solution Approach 2:
The patent utilizes the hydraulic system to deliver lubricating oil to the hydraulic cylinder's moving parts. By employing the existing hydraulic infrastructure, the system efficiently distributes lubrication where needed, reducing friction and maintaining pressing force reliability.
