Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a small needle mode glue dispenser is used, then the glue dispensing precision is improved, but the glue dispensing needle cylinder capacity is limited requiring frequent replacement
Solution Approach 1:
The patent implements continuous glue supply by connecting a large capacity feed tank to the glue dispensing needle cylinder through a replenishing mechanism. The feed tank automatically replenishes the needle cylinder when glue level drops, eliminating interruptions and ensuring continuous operation without manual intervention for replacement.
Solution Approach 2:
The patent divides the glue storage system into two segments: a large capacity feed tank for bulk storage and a small capacity glue dispensing needle cylinder for precise dispensing. This segmentation allows the feed tank to supply glue continuously to the needle cylinder, maintaining precision while eliminating frequent replacements.
2Productivity
If a replenishing tank is used to continuously replenish the glue dispensing needle cylinder, then the operation continuity is improved, but glue overflow occurs due to lack of control mechanism
Solution Approach 1:
The patent employs fluid level detecting units that continuously monitor the glue level in the needle cylinder and provide feedback to the control unit. When the glue level reaches a predetermined threshold, the control unit automatically stops the replenishment process, preventing overflow while maintaining continuous operation.
Solution Approach 2:
The replenishing mechanism dynamically adjusts its operation based on real-time glue level conditions. The system transitions between replenishing mode and stopped mode automatically, with the control valve opening and closing based on fluid level feedback, ensuring continuous operation without overflow.
3Ease of operation
If frequent replacement of glue dispensing needle cylinder is performed, then the glue level control is simplified, but manpower and cost increase
Solution Approach 1:
The system performs self-service through automated replenishment. The fluid level detecting units and control unit work together to automatically monitor glue levels and trigger replenishment when needed, eliminating the need for manual monitoring and replacement while reducing overall system complexity through automation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures continuous glue supply, reduces manpower and time wastage, and lowers costs by automatically replenishing the glue dispensing needle cylinder and preventing glue overflow, while allowing for efficient control of glue flow direction.
Implementation Method 1
controls the flowing direction of the glue via a control valve in order to replenish the glue dispensing needle cylinder with the glue
Implementation Method 2
The first fluid level detecting unit is disposed on the glue dispensing needle cylinder in order to detect the position of the fluid level of the glue inside the glue dispensing needle cylinder. The second fluid level detecting unit is disposed on the feed tank in order to detect the position of the fluid level of the glue inside the feed tank.
Data Source
AI summary
A glue dispensing system and the glue supplying method thereof are disclosed. The glue dispensing system uses at least one feed tank to provide or supply the glue to a glue dispensing needle cylinder. Thus, the glue dispensing needle cylinder does not need to be replaced or the frequency of replacing the glue dispensing needle cylinder can be decreased in order to save more time, reduce manpower waste and decrease the cost.
