Solution Overview

Problem

Existing forestry and agricultural trailer workstations lack a simple, adaptable structure that can withstand mechanical loads and prevent damage to essential components during use, particularly when handling varying loads and equipment.

Innovation Solution

A trailer workstation with a frame consisting of a central tube and auxiliary tubes, featuring longitudinally displaceable axle carriers, hydraulically extendable support legs, and a console for a loading crane, along with an extension bridge and protective features like plastic caps and grip strips on stanchions, allowing for stability and easy handling of loads without risking damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the frame structure is simplified for ease of manufacture, then manufacturing cost and complexity are reduced, but structural strength and stability under mechanical loads may be compromised

Engineering Contradiction:
Improveframe construction simplicityVSAvoidstructural strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The frame is divided into a central tube and two auxiliary tubes, creating a segmented structure that is both simple to manufacture and mechanically strong. This segmentation allows each component to be produced independently and assembled easily, while the distributed structure provides adequate strength to withstand mechanical loads during forestry and agricultural operations.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the workstation is designed with fixed components for structural stability, then mechanical strength is maintained, but adaptability to different loads and equipment is reduced

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability to loads and equipment
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The stanchions are designed to be exchangeable and repositionable along the auxiliary tubes, transforming the structure from static to dynamic. This allows the workstation to adapt to different load requirements and equipment configurations while the overall frame structure remains stable. The stanchions can be moved to optimal positions depending on the specific forestry or agricultural task being performed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The console on the trailer head is designed to receive various types of work equipment including loading cranes, making the workstation universal. The same basic frame structure supports multiple different equipment types and configurations, allowing a single workstation to perform multiple forestry and agricultural functions.

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

3Reliability

If protective features are added to prevent damage to components, then component reliability is improved, but device complexity increases

Engineering Contradiction:
Improvecomponent protectionVSAvoidprotective feature complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The stanchions are equipped with protective caps and grip strips as standard features, providing beforehand protection against damage during handling and operation. These protective elements are integrated into the basic design rather than added as separate complex systems, preventing damage before it occurs while maintaining simplicity.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

AI summary

The work station has a frame (1) provided with an axle carrier (2), an axle and wheels (4), and fastened at a post (9). A console (5) is located at a trailer head to receive a derrick. The frame is provided with a central tube (6) and two parallel running auxiliary frame tubes (7), where a set of recesses (8) is arranged in the respective auxiliary frame tubes for receiving an anti-swiveling post retainer. The axle carrier is arranged in the frame in a longitudinally displaceable manner. A set of hydraulic extensible lateral supporting legs (10) is formed at the trailer head.
