Problem

Existing solder supply devices require complex construction and increased space due to the need for air cylinders or electromagnetic motors to increase pressure for solder dispensing, making them bulky and costly.

Innovation Solution

A solder supply device that uses a piston and air chamber mechanism within the solder container to increase pressure internally, eliminating the need for external air cylinders or electromagnetic motors, allowing for compact design and simplified construction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an air cylinder or electromagnetic motor is used to increase pressure inside the solder container, then solder can be supplied effectively, but the device construction becomes complex and the device size increases

Engineering Contradiction:
Improvesolder supply functionalityVSAvoidconstruction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the pressure generation function directly into the solder container by integrating a piston mechanism that moves relative to the container. The container body itself becomes part of the pressure generation system, eliminating the need for separate air cylinders or electromagnetic motors. This merging of functions reduces construction complexity while maintaining solder supply capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The piston is positioned inside the solder container, with the piston rod extending through the container wall. The air chamber is nested within the container structure, with the piston moving within the container's internal space. This nested arrangement eliminates external pressure-generating components and reduces overall device size.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If an air cylinder or electromagnetic motor is provided to increase pressure, then solder supply is achieved, but the device occupies more space

Engineering Contradiction:
Improvesolder supply capabilityVSAvoiddevice volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The piston mechanism is nested within the solder container, with the piston moving inside the container's internal volume. The air chamber is integrated into the container structure, utilizing the container's own space for pressure generation. This eliminates the need for external air cylinders or motors, significantly reducing the device's overall volume.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The pressure generation system is merged with the solder container structure itself. The container body serves dual purposes: holding solder and providing the chamber for the piston mechanism. This integration eliminates separate pressure-generating components and reduces the total device volume.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If external pressure-increasing components are used, then solder can be dispensed, but the construction becomes more costly

Engineering Contradiction:
Improvesolder dispensing functionVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent merges the pressure generation function into the solder container structure, eliminating the need for separate air cylinders or electromagnetic motors. This integration reduces the number of components that need to be manufactured and assembled, thereby reducing manufacturing costs while maintaining solder dispensing functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention extracts and eliminates the complex and costly external pressure-generating components (air cylinders or electromagnetic motors) by replacing them with a simpler integrated piston mechanism. This extraction of unnecessary components reduces manufacturing complexity and cost.

Inventive Principle:
Principle #2Taking out (Extraction)
