Solution Overview

Problem

Existing pouching machines rely on spring pressure to hold clamps closed, requiring external mechanical force for opening and closing, which is inefficient and prone to inadvertent separation during operations.

Innovation Solution

A magnetic pouch clamp assembly using slidably connected clamping arms with opposing magnets to maintain the closed or open position through magnetic attraction, supplemented by a mechanical latching assembly to hold the open position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If spring pressure is used to hold clamps closed, then the clamp can maintain closed position, but external mechanical force is required for opening and closing operations

Engineering Contradiction:
Improveclamp closed position maintenanceVSAvoidopening and closing operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the traditional spring pressure mechanism with a magnetic field-based holding system. Magnets embedded in the clamp arms generate magnetic attraction forces that hold the clamp in the closed position without requiring continuous mechanical spring pressure, thereby eliminating the need for external mechanical force during opening and closing operations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The clamp system uses periodic engagement of mechanical latches during opening and closing cycles. The latches engage at specific positions to assist the magnetic field in maintaining the closed position and to facilitate smooth opening transitions, creating a periodic action pattern that improves operational ease.

Inventive Principle:
Principle #19Periodic action

2Ease of operation

If external mechanical force is applied to open and close clamps, then the clamp can change position, but inadvertent separation may occur during operations

Engineering Contradiction:
Improveclamp position changeVSAvoidpouch retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces continuous mechanical force application with a magnetic field-based holding system. The magnetic attraction between oppositely polarized magnets embedded in the clamp arms provides reliable pouch retention without requiring continuous external mechanical force, thereby preventing inadvertent separation during operations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The mechanical latching assembly provides beforehand cushioning by engaging at specific positions to prevent inadvertent separation. The latches are positioned to engage before potential separation issues can occur, providing a safety mechanism that reinforces the magnetic holding force.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If spring pressure is used to hold clamps closed, then the clamp can maintain closed position, but continuous mechanical force application is required

Engineering Contradiction:
Improveclamp closed position maintenanceVSAvoidmechanical force application
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent replaces the energy-consuming spring pressure mechanism with a magnetic field-based holding system. The magnets generate holding forces through magnetic attraction without requiring continuous mechanical force application or energy input, thereby reducing the use of energy while maintaining reliable closed position.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic field system provides self-service by automatically maintaining the closed position through magnetic attraction without requiring external energy input or continuous mechanical force application. The system serves itself by utilizing the inherent magnetic properties of the embedded magnets.

Inventive Principle:
Principle #25Self-service
