Innovation Solution

An operation control method and system that includes a display processing unit and a setting processing unit to display a horizontal control operation screen and perform settings related to the tilt control of the work implement with respect to the machine body, allowing users to adjust tilt angles through a control operation unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment of work implement tilt is used, then the machine can perform horizontal control, but work efficiency decreases depending on user skill level

Engineering Contradiction:
Improvehorizontal control operationVSAvoidwork efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent replaces manual mechanical adjustment of the work implement tilt with an automated control system that uses sensors to detect the machine body's tilt angle and automatically adjusts the work implement's horizontal position, substituting the mechanical manual operation with an automated control mechanism

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

Solution Approach 2:

The system enables the work machine to automatically adjust its own work implement horizontal control based on detected tilt angles without requiring external manual intervention, making the system self-regulating and independent of operator skill level

Inventive Principle:
Principle #25Self-service

2Productivity

If automated horizontal control is implemented, then work efficiency improves, but device complexity increases

Engineering Contradiction:
Improvework efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control system is designed to perform multiple functions: detecting machine body tilt angle, calculating required work implement adjustment, and executing the horizontal control, allowing a single integrated system to handle various control tasks rather than requiring separate specialized components for each function

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

Solution Approach 2:

The patent introduces a control unit as an intermediary component that receives tilt angle detection signals and translates them into appropriate control commands for the work implement, serving as a mediator between the sensing system and the actuation mechanism

Inventive Principle:
Principle #24Intermediary (Mediator)
