Solution Overview

Problem

Existing garden and forestry equipment systems lack user-friendly features that enhance operational efficiency and safety, particularly in handling heavy devices and navigating complex environments.

Innovation Solution

A garden and forestry system comprising a hand-held processing device and a separate assistance device, which can be controlled wirelessly through a user-actable control element. The assistance device supports the user by providing automatic assistance and issuing information through an output device, enhancing safety and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the user operates the gardening device with one hand, then the ease of operation is improved, but the ability to control assistance functions is lost

Engineering Contradiction:
Improveease of operationVSAvoidcontrol capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The handle integrates multiple functions: it serves as both the gripping element for operating the gardening device and as a control interface for the assistance device. The control element on the handle allows the user to control both the gardening device and the assistance device through a single unified interface, eliminating the need for separate controls.

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

2Adaptability or versatility

If the user lets go of the gardening device to control the assistance device, then the control capability is improved, but the operational continuity is interrupted

Engineering Contradiction:
Improvecontrol capabilityVSAvoidoperational continuity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The control element for the assistance device is merged with the handle of the gardening device. This integration allows the user to control the assistance device without releasing the gardening device, maintaining continuous operation and eliminating interruptions in the workflow.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the control element is integrated into the handle, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control system is segmented into a wireless communication module that receives signals from the control element on the handle and processes them independently. This segmentation allows the control functionality to be added without significantly complicating the main gardening device structure, as the control and power systems are kept separate and modular.

Inventive Principle:
Principle #1Segmentation
