Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing devices for dispensing active ingredient-containing or active ingredient-carrying strips lack the ability to provide a substantially uniform active ingredient dose, relying on battery-fed electric drives and complex control systems.

Innovation Solution

A mechanical indexing coupling mechanism is introduced, allowing for manual actuation to drive the output roller in incremental steps, ensuring a defined angle of rotation and subsequent severing of strips, operating purely mechanically without the need for electric components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a battery-fed electric drive with electric control device is used, then the dosing quantity can be controlled, but the device complexity and reliance on power sources increase

Engineering Contradiction:

Improvedosing quantity controlVSAvoidelectric control system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the battery-fed electric drive system with a purely mechanical indexing coupling mechanism. The indexing mechanism uses a manually actuatable triggering element that drives the output roller in incremental steps through mechanical indexing, eliminating the need for electric motors, batteries, and electronic control devices while maintaining precise dosing quantity control

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The mechanical indexing coupling mechanism is designed to be manually operated by the user through a triggering element, making the system self-sufficient without external power sources. The mechanism automatically indexes the output roller through defined angular positions based on manual actuation, providing self-contained operation

Inventive Principle:

Principle #25Self-service

2Productivity

If a battery-fed electric drive is used, then the band can be conveyed and strips can be severed, but the device requires power sources and becomes less portable

Engineering Contradiction:

Improveband conveying and strip severingVSAvoidbattery power consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent replaces the electric drive system with a manual mechanical indexing mechanism. The triggering element mechanically indexes the output roller through a wheel transmission system, conveying the band and enabling strip severing through purely mechanical means without any power consumption

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If an indexing coupling mechanism with manual actuation is used, then the device operates purely mechanically without batteries, but the manual operation requires user effort

Engineering Contradiction:

Improveelimination of electric componentsVSAvoidmanual actuation effort

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The indexing coupling mechanism is designed with a manually actuatable triggering element that provides dynamic, step-by-step indexing of the output roller. Each actuation of the triggering element rotates the drive wheel through a defined angle, conveying a precise length of band and enabling controlled strip dispensing through repetitive manual motion

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The mechanism operates through periodic manual actuation of the triggering element, where each actuation cycle indexes the output roller through a fixed angular displacement, conveying a consistent length of band and enabling regular strip dispensing intervals through repeated manual operation

Inventive Principle:

Principle #19Periodic action
