Nozzle Unit Slit Width Regulation Motor Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nozzle units for applying damping material require complex disassembly to adjust the slit width of the discharge port, which complicates the process and can interfere with complex-shaped work pieces, especially when the motor is large and protrudes from the nozzle.
Innovation Solution
A nozzle unit with a motor fixed to the nozzle such that its rotary shaft extends in the direction of material discharge, using a rotation transmitting device to adjust the slit width through a second rotary shaft, allowing for precise control of the slit width without protruding and interfering with the work piece, and a controller to manage the application parameters for uniform thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the motor is made large to provide sufficient torque for adjusting the slit width, then the adjusting capability is improved, but the motor protrudes from the nozzle and interferes with complex-shaped work pieces
Solution Approach 1:
The patent changes the spatial orientation of the motor from a protruding configuration to an integrated configuration where the motor's rotary shaft extends in the direction of material discharge. This dimensional reorientation allows the motor to be positioned within the nozzle structure rather than protruding outward, eliminating interference with complex-shaped work pieces while maintaining sufficient torque for slit width adjustment.
2Ease of operation
If the slit width adjustment mechanism is simplified for easy operation, then the ease of operation is improved, but the precision of slit width control may be compromised
Solution Approach 1:
The patent replaces complex mechanical adjustment mechanisms with a motor-driven system that uses rotational motion to control the slit width. The motor's rotary shaft is directly coupled to the slit width adjustment mechanism, enabling precise control through electrical signals while maintaining ease of operation through automated or semi-automated control. This substitution of mechanical systems with an electromechanical system achieves both ease of operation and precision control.

AI summary
A nozzle unit for applying damping material onto a work piece includes a nozzle that has a slit-like discharge port and that discharges the damping material from the discharge port; a motor that is fixed to the nozzle; and a slit width changing device that changes the slit width of the discharge port using rotation of the motor.
