Solution Overview

Problem

Existing remotely controlled forestry machines lack provisions for maintaining operator comfort by keeping food and clothing warm and dry in varying weather conditions.

Innovation Solution

Integration of storage compartments within the hood-like housing that are heated by waste heat from the drive unit components, such as the internal combustion engine and hydraulic pumps, to maintain warmth for food and clothing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If storage compartments are added to the machine for keeping food and clothing warm, then operator comfort is improved, but the machine's external dimensions would increase

Engineering Contradiction:

Improveoperator comfortVSAvoidmachine external dimensions

Core Design Contradiction:

Ease of operationVSLength of stationary object

Solution Approach 1:

The storage compartments are nested inside the hood-like housing, utilizing the internal space of the existing structure. The compartments are positioned within the hood to exploit waste heat from the drive unit while maintaining the compact external dimensions of the machine.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The waste heat generated by the drive unit (internal combustion engine and hydraulic pumps) during operation is converted into a beneficial resource for heating the storage compartments. This eliminates the need for separate heating systems while providing warmth for food and clothing storage.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Ease of operation

If heating system is added to storage compartments, then food and clothing can be kept warm, but energy consumption increases

Engineering Contradiction:

Improvestorage heating capabilityVSAvoidenergy consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The waste heat from the drive unit, which would otherwise be dissipated into the environment, is captured and utilized for heating the storage compartments. This converts a harmful waste product into a useful heating source, eliminating additional energy consumption.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The drive unit's waste heat automatically serves the heating function of the storage compartments without requiring additional energy input or active control systems. The heating is a byproduct of the normal operation of the drive unit.

Inventive Principle:

Principle #25Self-service

AI summary

The present disclosure relates to a mobile machine, in particular a forestry machine, which has a chassis and a drive unit which has an internal combustion engine and at least one hydraulic pump driven by the internal combustion engine, which hydraulic pump supplies a hydraulic system with pressure medium. The internal combustion engine with the hydraulic pump is located in an engine compartment formed inside a hood-like housing. The machine has no driver workplace for an operator and is in the form of a machine that can be remotely controlled by means of a remote control. Inside the hood-like-housing there is at least one storage compartment that can be heated by the waste heat of the drive unit.
