U-Shaped Adhesive Dispensing Assembly with Rotating Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring adhesive dispensing guns are difficult to use, especially in cold temperatures, as they require high dispensing pressure and cause user fatigue, leading to musculoskeletal disorders due to awkward positions and forceful contractions.
Innovation Solution
A U-shaped adhesive dispensing assembly with a screw receiving portion, cartridge holding portion, screw member, plunger pad, handle, and bolt head that allows for efficient dispensing of adhesive using an electric drill or socket wrench, reducing user strain and improving handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high dispensing pressure is applied to dispense high-viscosity adhesive, then the adhesive can be dispensed, but the dispensing gun breaks or causes excessive user fatigue
Solution Approach 1:
The dispensing mechanism is divided into separate functional components: a handle for user operation, a plunger for applying pressure, and a cartridge holder for containing the adhesive. This segmentation allows each component to be optimized independently, with the plunger designed to handle high pressures without requiring the entire gun structure to withstand them, thereby preventing breakdown while maintaining dispensing capability.
Solution Approach 2:
The plunger acts as an intermediary mechanism between the user's manual input and the adhesive dispensing process. Instead of requiring the user to directly apply high pressure to the adhesive, the plunger transmits this force gradually and controlledly, reducing the peak stresses on the dispensing gun structure while still achieving the necessary dispensing pressure.
2Productivity
If high dispensing pressure is applied to dispense high-viscosity adhesive, then the adhesive can be dispensed, but user fatigue and musculoskeletal disorders increase
Solution Approach 1:
The operation is segmented into a rotating handle motion and a linear plunger movement. This conversion of rotational to linear motion allows users to apply force more efficiently through a natural rotating motion rather than repeated forceful contractions, reducing fatigue while maintaining the necessary dispensing pressure.
Solution Approach 2:
The mechanism transitions from static high-pressure application to dynamic rotational motion. The handle can be rotated continuously or intermittently, allowing the user to control the rate of adhesive dispensing and take breaks without compromising the dispensing pressure, thereby reducing overall user fatigue.
3Productivity
If conventional dispensing guns are used for high-viscosity adhesive, then the adhesive can be dispensed, but awkward wrist positions and repetitive finger contractions are required
Solution Approach 1:
The handle is designed to rotate freely, allowing the user to naturally adjust the angle and position of their wrist and hand. This dynamic rotation eliminates the need for awkward fixed positions, as the user can comfortably hold the handle at any angle that suits their body mechanics while still achieving the necessary dispensing action.
Solution Approach 2:
The separation of the handle from the main gun body allows the handle to be positioned and oriented independently, enabling users to find ergonomic positions that reduce wrist strain. The handle can be rotated and positioned at optimal angles without affecting the structural integrity or dispensing capability of the overall system.
