Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of the adjustment rod is used to change adhesive dripping amount, then the operation is simple in structure, but the operation is inconvenient, time-consuming, and difficult to ensure precise adhesive dripping amount
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an electromagnetic control system. The electromagnetic coil generates magnetic force to drive the core stem and adhesive dripping assembly, substituting manual rod adjustment with automated electromagnetic actuation. This enables precise control of adhesive dripping amount through electrical signals while improving operational convenience.
Solution Approach 2:
The patent implements a feedback control mechanism where the pressure sensor detects pressure changes in the mounting chamber caused by adhesive dripping, and the control unit adjusts the electromagnetic coil current accordingly. This closed-loop feedback system ensures precise control of adhesive dripping amount by continuously monitoring and adjusting the dripping process based on actual pressure conditions.
2Productivity
If manual adjustment of the adjustment rod is used to change adhesive dripping amount, then the structure is simple, but the operation is time-consuming
Solution Approach 1:
The electromagnetic control system replaces manual mechanical adjustment, enabling rapid response and control of adhesive dripping amount without the time-consuming manual rod adjustment process. The electromagnetic coil can quickly change its magnetic field strength to adjust the dripping assembly position and adhesive flow rate instantaneously.
Solution Approach 2:
The patent employs periodic pulsed control of the electromagnetic coil to achieve precise adhesive dripping. The control unit can apply periodic electrical signals to the electromagnetic coil, creating controlled periodic motion of the adhesive dripping assembly that enables precise dosage control while improving operational efficiency.
3Measurement precision
If manual adjustment of the adjustment rod is used, then no additional control components are needed, but the operation depends on operator proficiency and experience
Solution Approach 1:
The pressure sensor and control unit form a feedback control system that automatically adjusts the electromagnetic coil current based on detected pressure changes. This eliminates dependency on operator proficiency by using automated sensing and control, achieving precise adhesive dripping amount control through objective pressure-based feedback rather than subjective manual judgment.
Solution Approach 2:
The system performs self-adjustment through the feedback mechanism where the pressure sensor automatically detects dripping conditions and the control unit autonomously adjusts the electromagnetic coil current accordingly. The system serves itself by automatically compensating for variations in adhesive properties, temperature, and other conditions without requiring operator intervention or expertise.
