Hybrid Material Dispensing Device Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional material application devices are heavy and difficult to mount on desk-top robots due to their weight, making them inefficient for use in material dispensing applications.
Innovation Solution
A material application device with a pushing part that uses a combination of a motor-driven first driving part and a fluid-driven second driving part to impart force to a pushing member, which includes a sealing member and a clamping member to discharge materials from a storage container, reducing the overall device weight and improving temperature stability of material dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a motor and ball screw are used to rotationally drive a piston shaft for pushing out material, then the material can be discharged from the storage container, but the device becomes relatively heavy in weight
Solution Approach 1:
The patent uses a piston shaft that is pushed by air pressure (pneumatics) instead of a motor and ball screw system. The air pressure source pushes the piston shaft to discharge material from the storage container, eliminating the need for heavy mechanical driving components while maintaining the necessary pushing force.
2Reliability
If a sealing member is used to seal the gap between the plunger and filling part, then material leakage is prevented, but the device complexity increases due to additional clamping mechanism
Solution Approach 1:
The clamping mechanism is segmented into a simple two-point clamping system using clamping members that can be independently positioned. This segmentation allows the sealing member to be effectively clamped between the piston shaft and filling part without requiring a complex integrated clamping mechanism, thus maintaining reliability while reducing overall device complexity.

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 device effectively reduces weight, enhances temperature stability of material dispensing, and allows for more precise control over material application, making it suitable for use on desk-top robots without increasing the device's size or weight significantly.
Implementation Method 1
The second driving part is configured to be able to impart a driving force to the pushing part by supplying a fluid into an inner space isolated from the outside
