Solution Overview

Problem

Existing multifunctional lifting vehicles require costly and time-consuming modifications to their control systems to accommodate new equipment types, and manufacturers may refuse to approve unknown equipment, limiting operational flexibility and safety due to the need for pre-defined load diagrams.

Innovation Solution

A control system with an electronic control unit and human-machine interface that can recognize and calculate a load diagram for both predetermined and unknown equipment types, allowing manual entry of parameters to determine safe operating limits, displayed on a user interface, enabling operation within defined working areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the control system uses pre-defined load diagrams for predetermined equipment, then safety is ensured, but adaptability to new equipment types is reduced

Engineering Contradiction:
ImprovesafetyVSAvoidadaptability to new equipment
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The control system automatically recognizes new equipment types through RFID tags or manual input and autonomously generates appropriate load diagrams without requiring manufacturer intervention. The system serves itself by expanding its equipment database and adapting safety parameters dynamically.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The load diagram is transformed from a static, pre-defined configuration to a dynamic structure that adapts in real-time based on detected equipment type. The control system dynamically generates customized load diagrams matching the specific characteristics of each equipment piece.

Inventive Principle:
Principle #15Dynamics

2Reliability

If manufacturer approval is required for new equipment, then safety standards are maintained, but implementation time and cost increase

Engineering Contradiction:
Improvesafety standardsVSAvoidimplementation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary equipment recognition and load diagram generation automatically upon equipment attachment, eliminating the need for time-consuming manufacturer approval processes. Safety standards are maintained through automated validation against pre-established criteria.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The manual manufacturer approval process is replaced with an automated electronic recognition and validation system using RFID tags, sensors, and algorithmic load diagram generation, dramatically reducing implementation time while maintaining safety.

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

3Adaptability or versatility

If the control system stores multiple predetermined equipment types, then versatility is improved, but device complexity increases

Engineering Contradiction:
Improveequipment compatibilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control system implements a universal equipment recognition framework using RFID tags and standardized identification protocols that work across all equipment types. This single universal interface replaces the need for multiple specialized recognition systems.

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

Solution Approach 2:

Instead of storing complete physical specifications for every possible equipment variant, the system uses RFID tags and identification codes as simplified copies or representations of equipment characteristics, enabling recognition without storing extensive detailed data.

Inventive Principle:
Principle #26Copying
