Solution Overview

Problem

Existing harvesting machines lack an efficient method to automatically control the operation of side elements used for dividing harvested crops, leading to unnecessary energy consumption and reduced element lifespan due to continuous operation or cumbersome manual switching, especially during field turning operations.

Innovation Solution

An electronic control device is integrated to automatically switch the drive of side elements on or off based on operating data, such as position determination systems, sensors, or camera image processing, to determine the presence of crops and adjust element operation accordingly, reducing unnecessary operation and enhancing operator ease.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the side elements are continuously operated to ensure crop division functionality, then the harvesting process can proceed without interruption, but energy consumption increases and element lifespan decreases

Engineering Contradiction:
Improveharvesting continuityVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The side elements are designed with dynamic on/off capability, allowing their operation state to change based on real-time harvesting conditions. The electronic control device dynamically switches the drive motors on or off depending on whether crop division is currently needed, transforming a static continuous operation system into a dynamic conditional operation system that optimizes energy consumption while maintaining harvesting productivity.

Inventive Principle:
Principle #15Dynamics

2Use of energy by moving object

If manual switching of side elements is implemented to reduce energy consumption, then unnecessary operation can be avoided, but operator workload increases during critical operations

Engineering Contradiction:
Improveenergy consumptionVSAvoidoperator workload
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The system implements self-service automation where the electronic control device autonomously monitors harvesting conditions and automatically switches the side elements on or off without requiring operator intervention. The control device uses operating data from sensors and position determination systems to make intelligent decisions about when side elements are needed, freeing the operator from manual switching tasks while optimizing energy consumption.

Inventive Principle:
Principle #25Self-service

3Use of energy by moving object

If automated control using position determination systems is implemented, then element operation can be optimized, but device complexity increases

Engineering Contradiction:
Improveenergy consumptionVSAvoidcontrol system complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The electronic control device serves multiple functions: it monitors operating data from various sensors, processes position information from determination systems, controls the switching of side elements, and optimizes energy consumption. By consolidating these diverse functions into a single multi-functional control unit, the system achieves automated optimization without proportionally increasing overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
