Resilient Dispensing Gun Member for Steady Viscous Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand-held lever action dispensing guns, such as caulking guns, suffer from inconsistent product flow due to the need for re-cocking the hand lever, leading to disrupted flow and gaps in the application, requiring skilled operation to maintain consistency.
Innovation Solution
The use of a resiliently deformable member, such as a compression spring or air bladder, integrated into the dispensing gun or viscous material container, which modulates flow by storing and releasing energy to maintain consistent pressure during re-cocking, ensuring a steady flow of viscous materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a hand-held lever action dispensing gun is used, then the device complexity is low and cost is reduced, but the product flow consistency deteriorates due to re-cocking interruptions
Solution Approach 1:
The resiliently deformable member is pre-compressed by the plunger during the cocking phase, storing elastic potential energy before dispensing begins. This preliminary energy storage ensures that when the lever is released, the stored energy immediately drives consistent material flow without interruption or gaps, resolving the flow consistency issue while maintaining simple hand-held lever action device design
2Ease of operation
If pressure is applied by compressing a hand lever, then the ease of operation is maintained, but the duration of continuous pressure application deteriorates due to re-cocking requirements
Solution Approach 1:
The system converts the periodic hand lever compression into continuous pressure application through the resiliently deformable member. Each lever compression cycles the spring through compression and expansion phases, but the spring's continuous elastic deformation maintains unbroken pressure on the material throughout the entire dispensing cycle, eliminating gaps and extending effective pressure duration beyond what manual lever action alone could achieve
3Reliability
If a resiliently deformable member is added to modulate flow, then the product flow consistency is improved, but the device complexity increases
Solution Approach 1:
The resiliently deformable member is self-actuating through the natural compression and expansion cycles of the hand lever operation. It automatically compresses when the plunger advances and expands when the lever is released, modulating flow without requiring external control systems, sensors, or additional power sources. This self-regulating mechanism improves flow consistency while adding minimal structural complexity to the dispensing system
