Solution Overview

Problem

Conventional plant trimming devices require frequent maintenance and replacement of parts due to worn contact points between motors, tumblers, and blade mechanisms, leading to inefficiencies as belts lose tension and drive wheels lose contact points.

Innovation Solution

A removable motor housing that can be slidably or pivotably connected to the plant trimming device, utilizing a biasing device to maintain a constant force between the input and output shafts, allowing for easy adjustment and self-correction of motor positions, and featuring direct or indirect mechanical communication via gears, rollers, belts, or cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed motor housing is used in plant trimming devices, then the structure is simple and stable, but the contact points between motors, tumblers and blade devices become worn over time, necessitating constant maintenance and replacement of parts

Engineering Contradiction:
Improveoperational efficiencyVSAvoidmaintenance frequency
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The motor housing is made movable rather than fixed, allowing it to be repositioned along the tumbler to fresh contact points. The housing can slide or pivot to new positions, transforming from a static component to a dynamic one that can self-correct wear issues by changing its position relative to the tumbler and blade mechanisms.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If belts are used to transmit power from motors to tumblers, then the system is flexible and adaptable, but belts lose tension over time causing inefficiencies

Engineering Contradiction:
Improvetransmission flexibilityVSAvoidoperational efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The motor housing with belt transmission system is made dynamic, allowing the entire assembly to be repositioned when belt tension is lost. Instead of replacing the belt, the housing can be moved to a new position where the belt can be re-tensioned or replaced more easily, maintaining operational efficiency while preserving the flexible belt transmission advantage.

Inventive Principle:
Principle #15Dynamics

3Productivity

If drive wheels are used to transmit power, then the mechanical connection is direct and efficient, but drive wheels lose contact points over time

Engineering Contradiction:
Improvepower transmission efficiencyVSAvoidcontact point durability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The drive wheel assembly within the motor housing is made repositionable. When contact points are worn, the entire motor housing can be moved along the tumbler to engage with fresh sections of the tumbler surface, maintaining direct mechanical contact and power transmission efficiency while extending the overall system life.

Inventive Principle:
Principle #15Dynamics

4Stability of the object's composition

If motors are fixed in location relative to the tumbler and blade mechanisms, then the structure is stable, but worn contact points necessitate constant maintenance

Engineering Contradiction:
Improvestructural stabilityVSAvoidpart replacement frequency
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The motor housing is designed to be movable along the tumbler while maintaining stable operation. The housing can slide or pivot to new positions, providing structural stability during operation but allowing positional changes for maintenance. This dynamic capability enables the system to reset worn contact points without replacing entire components.

Inventive Principle:
Principle #15Dynamics
