Solution Overview
Problem
Traditional electronic fountain devices are limited by their large size, which prevents them from being set off at multiple angles due to consumable blockages in the ejection tube, compromising user experience and functionality.
Innovation Solution
A handheld intelligent electronic fountain device with a material guiding component featuring a first rotating shaft and transmission gear system that can reverse rotate to overcome blockages, allowing for efficient and intelligent removal of consumable obstructions, enabling operation at various angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the device uses a fixed material guiding tube structure, then the device size can be reduced for handheld portability, but consumables will block the ejection tube when set off at multiple angles
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed material guiding tube into a rotatable structure. The first material guiding tube can rotate relative to the housing, and the first rotating shaft can rotate to adjust the angle of the ejection tube. This dynamic adjustment allows the device to be set off at multiple angles (0-360 degrees) without consumable blockage, while maintaining a compact handheld size when not in use.
2Device complexity
If the transmission gear rotates slowly with low torque, then the device structure remains simple, but it cannot overcome blockages caused by consumables
Solution Approach 1:
The patent applies periodic action through the reciprocating rotation of the transmission gear. The gear rotates forward to drive the rotating shaft during normal operation, then reverses and rotates backward with increased torque to clear blockages. This periodic alternation between low-torque forward rotation and high-torque reverse rotation enables the system to both operate normally and clear obstructions without requiring a completely separate high-torque mechanism.
Solution Approach 2:
The patent changes the torque parameter of the transmission system dynamically. During normal material guiding, the gear rotates with lower torque. When blockage is detected or during the reverse stroke, the gear rotation direction changes and torque increases to overcome the blockage. This parameter change allows a single transmission system to handle both normal operation and blockage removal effectively.
3Ease of operation
If the first transmission gear rotates in the same direction continuously, then the material guiding is simple, but it cannot release blockages in the ejection tube
Solution Approach 1:
The patent applies the inversion principle by making the transmission gear rotate in reverse direction to clear blockages. During normal operation, the gear rotates in one direction to guide materials smoothly. When blockage occurs, the gear reverses its rotation direction, causing the rotating shaft to rotate in the opposite direction, which dislodges and removes the blockage from the ejection tube.
