Solution Approach 1:

The patent replaces manual mechanical adjustment with an automated electronic system. A smartphone or tablet with sensors (accelerometer, gyroscope) automatically measures the actual movement parameters of the handling device and uses application software to calculate optimal shock absorber settings, eliminating the need for time-consuming manual trial-and-error adjustment while ensuring precise parameter settings.

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

Solution Approach 2:

The handling device performs self-diagnosis and self-adjustment through the automated measurement and calculation system. The device itself generates the data needed for optimization through its own operation, and the system automatically determines the correct parameters without external intervention, enabling rapid and accurate setup.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If shock absorber parameters are incorrectly adjusted, then the handling device can operate, but this leads to overstressing, wear, and premature failure

Engineering Contradiction:
Improveoperational simplicityVSAvoidbraking system durability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system continuously monitors the actual movement parameters of the handling device using sensors in the smartphone or tablet. By comparing measured values with target values and automatically calculating optimal shock absorber settings, the system provides real-time feedback to ensure parameters are always correctly adjusted, preventing overstressing and wear while maintaining simple operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary measurement and calculation of optimal parameters before actual operation begins. By determining the correct shock absorber settings in advance based on measured movement characteristics, the system prevents incorrect adjustment from causing damage, ensuring reliability before the handling device is put into service.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If varying masses are handled regularly, then the handling device is versatile, but this necessitates frequent adjustments to end-position damping

Engineering Contradiction:
