Solution Overview

Problem

Existing telescopic loading devices in charging vehicles face challenges in achieving stable and collision-free movement of the loading tool, requiring significant operator attention and effort to avoid obstacles and maintain stability, especially when loading or unloading materials.

Innovation Solution

The telescopic loading device is equipped with a swivel drive and control system that divides the movement path into sections, allowing for targeted and collision-free movement by requiring operator approval before transitioning to the next section, ensuring stability and preventing collisions, with adaptable movement sequences based on load conditions and specific applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the loading tool is guided on a curved path to enable vertical movement close to obstacles, then the loading tool can approach vertically extending obstacles, but the operator must maintain high attention to avoid collisions and unnecessary movements

Engineering Contradiction:
Improveability to approach obstaclesVSAvoidoperator attention required
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The automated guiding function is divided into multiple independent guiding sections (first guiding section, second guiding section, etc.). Each section can be independently activated and controlled, allowing the operator to manage the loading tool's movement in discrete steps rather than as a continuous automated sequence, thereby reducing cognitive load and attention requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A control device acts as an intermediary between the operator and the automated guiding system. This control device manages the transition between guiding sections and coordinates the automated movements, shielding the operator from directly managing complex automated sequences while still enabling controlled approach to obstacles.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the telescopic arm extension and swiveling are limited by control systems to maintain stability, then vehicle stability is improved, but the loading tool's movement flexibility is restricted

Engineering Contradiction:
Improvevehicle stabilityVSAvoidloading tool movement flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The control system dynamically adjusts the limiting values for telescopic arm extension and swiveling based on the loading tool's position and the selected guiding section. As the loading tool progresses through different guiding sections, the control device modifies the permissible movement ranges, allowing maximum flexibility when stability is not compromised and enforcing limits only when necessary for stability.

Inventive Principle:
Principle #15Dynamics

3Productivity

If automated movement of the loading tool is implemented, then movement efficiency is improved, but the operator must override the automated movement to perform loading or unloading work steps

Engineering Contradiction:
Improvemovement efficiencyVSAvoidoperator intervention required
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The automated guiding path is segmented into multiple sections, with the ability to pause or stop at specific sections. This allows the operator to intervene at predetermined points in the sequence to perform loading or unloading operations, rather than requiring continuous override of the automated system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system automatically manages the guiding sequence and positions the loading tool at appropriate locations for loading/unloading operations. The operator only needs to trigger the automated sequence and perform simple loading/unloading actions, rather than manually controlling the entire movement and positioning process.

Inventive Principle:
Principle #25Self-service
