Fluid Dispenser Drive Segmentation for Compact Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid applicator apparatuses require significant structural space for their drive devices, leading to potential collisions and operational inefficiencies due to the need for extensive support structures, which complicates mobility and installation.
Innovation Solution
A compact clamping device is introduced to fix the closure body in various positions, allowing the drive device to be separated from the closure body, reducing structural space requirements and enabling quick assembly and disassembly without complex or expensive parts, using a piston rod and clamping screw mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional drive device with screwthreaded spindle and holding device is used to move the closure body, then the closure body can be displaced along the distributor passage, but the apparatus requires significant structural space in both longitudinal and radial directions
Solution Approach 1:
The drive device is segmented into a movable drive unit that can be detached from the closure body. The drive unit includes the screwthreaded spindle and holding device, while the closure body remains separate. This segmentation allows the drive device to be removed when not in use, reducing the structural space occupied by the apparatus while maintaining the ability to displace the closure body when needed.
Solution Approach 2:
The drive device transitions from a static, permanently mounted configuration to a dynamic, movable configuration. The drive unit can be moved into position to displace the closure body and then removed afterward. This dynamic approach allows the apparatus to occupy minimal space during non-operational periods while maintaining full functionality during operation.
2Ease of operation
If the screwthreaded spindle is made long enough to ensure mobility of the closure body between limit positions, then the closure body can be fully displaced, but additional structural space is required for the holding device and engagement portion
Solution Approach 1:
The drive device is divided into a movable drive unit containing the screwthreaded spindle and a separate closure body. The spindle length is optimized for functionality within the drive unit, while the drive unit itself can be positioned as needed. This segmentation allows the spindle to be sufficiently long for operation without requiring the entire apparatus to have extended dimensions.
3Reliability
If the drive device is integrated permanently with the closure body, then the closure body can be reliably displaced, but the apparatus cannot be compact and may collide with adjoining machines or walls
Solution Approach 1:
The drive device is made dynamically configurable rather than permanently integrated. The drive unit can be moved into position to perform closure body displacement reliably, then removed when not needed. This dynamic configuration eliminates the risk of collisions with adjoining machines or walls while maintaining reliable displacement functionality during operation.
Solution Approach 2:
The drive unit is extracted from permanent integration with the closure body and nozzle arrangement. It can be taken out when not in use, allowing the apparatus to have a compact profile that avoids collisions with surrounding equipment or structural elements while maintaining full operational capability when the drive unit is installed.
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 solution reduces structural space requirements, facilitates quick assembly and disassembly, and prevents collisions, while maintaining the mobility and functionality of the closure body, thereby enhancing operational efficiency and reducing downtime.
Implementation Method 1
The clamping element (72) is arranged movably in a bore (74) extending from the opening (70) into the interior of the housing (66). A clamping screw (76) is arranged in the housing (66), with its longitudinal axis being transverse to the longitudinal axis of the piston rod (30). The clamping element (72) is movable in the longitudinal direction by means of the clamping screw (76) and embraces the piston rod (30).

AI summary
A dispenser of viscous fluid, in at least one embodiment a hot melt glue adhesive, has a heater element, an adhesive source, a main common passage, and a series of valves that all fluidly connect to the main passage. A sheet of receiving material, such as an envelope, has hot melt glue applied to its surface as it passes under the series of valves. A variable amount of valves can be activated by moving control rods inwardly or outwardly of the main common passage. The moving control rods have indicator markers, a securing screw and are housed in U-shaped beds which collectively make adjusting the dispensing pattern very easy.
