Solution Overview

Problem

Chainsaw chains often become dull quickly and require frequent replacement, leading to inefficient work and untangling issues when stored haphazardly, especially in outdoor and hard-to-reach locations.

Innovation Solution

A device for releasably picking up and holding chainsaw chains, featuring a support structure with receiving, deflecting, and fixing elements that allow chains to be securely mounted and deflected in multiple planes, using magnets or clamping for retention, preventing tangling and facilitating organized storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If chainsaw chains are stored haphazardly, then storage is simple and quick, but the chains become tangled and difficult to untangle, delaying chain replacement

Engineering Contradiction:
Improveease of storageVSAvoidtime for untangling
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The chain storage device divides the chain into multiple sections (first chain section, second chain section, third chain section, fourth chain section) and stores each section in a dedicated location (receiving element, first deflecting element, fixing element). This segmentation prevents the chain from tangling while maintaining simple storage access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first deflecting element is designed to receive the second chain section in a first plane and the third chain section in a second plane. By utilizing multiple planes/dimensions, the device organizes the chain in three-dimensional space, preventing tangling while keeping the storage device compact and accessible.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If chainsaw chains are carried on tool belt or transport, then accessibility is improved, but chains may become tangled during transport

Engineering Contradiction:
Improveaccessibility of chainVSAvoidchain organization
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The device pre-organizes the chain into a specific configuration with defined receiving, deflecting, and fixing elements before the chain is needed. This preliminary organization ensures the chain remains untangled during transport while staying easily accessible on the tool belt or transport.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The deflecting elements act as intermediaries that guide and maintain the chain's configuration during transport. These elements mediate between the chain sections, preventing them from tangling while allowing the chain to remain accessible and easily removable when needed.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If multiple chain sections are deflected in the same plane, then the device structure is simpler, but chain sections may interfere with each other and cause tangling

Engineering Contradiction:
Improvedevice structureVSAvoidchain storage reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The first deflecting element is designed to receive the second chain section in a first plane and the third chain section in a second plane. By utilizing multiple planes, the device reliably stores chain sections without interference while maintaining reasonable structural complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The chain storage device employs a nested arrangement where chain sections are organized in a hierarchical manner across different planes and elements (receiving element, deflecting elements, fixing element). This nesting allows reliable storage without excessive structural complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)
