Solution Overview

Problem

Existing chain saws lack a guide wheel cooling system, leading to high temperatures during prolonged use, which reduces the service life of the product.

Innovation Solution

A guide wheel cooling liquid delivery system is introduced, featuring liquid inlet channels, an anti-blocking liquid outlet structure, and liquid guide channels that ensure stable cooling liquid delivery to the guide wheel, preventing debris blockage and ensuring smooth output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a cooling system is added to the chain saw guide plate, then the cooling and lubrication effect is improved, but the structural complexity increases

Engineering Contradiction:
Improveguide wheel temperatureVSAvoidguide plate structure
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The cooling liquid delivery system is integrated directly into the guide plate structure by forming liquid inlet channels and liquid guide channels as part of the guide plate's internal structure. This merging approach incorporates the cooling function without adding separate external cooling components, thus improving temperature control while minimizing increases in overall structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The guide plate is designed to serve multiple functions simultaneously: it provides structural support for the guide wheel, contains internal channels for cooling liquid delivery, and provides lubrication to the guide wheel bearings. This multi-functionality allows the cooling system to be embedded within the existing guide plate structure rather than requiring separate dedicated cooling components.

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

2Ease of manufacture

If a liquid outlet structure is exposed on the outer plate, then the liquid delivery is simplified, but debris blocking occurs

Engineering Contradiction:
Improveliquid outlet structureVSAvoidliquid outlet blocking
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The liquid outlet groove is nested within the inner plate structure rather than being exposed on the outer plate surface. The groove is positioned such that its opening faces the guide wheel installation area while being protected by the outer plate, creating a nested configuration that prevents debris from entering and blocking the outlet while maintaining the simplicity of the liquid delivery path.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Temperature

If cooling liquid channels are added to the guide plate, then the cooling effect is improved, but the structural strength may be reduced

Engineering Contradiction:
Improveguide plate temperatureVSAvoidguide plate strength
Core Design Contradiction:
TemperatureVSStrength

Solution Approach 1:

The liquid inlet channels and liquid guide channels are positioned strategically within the guide plate structure to provide cooling where it is most needed (near the guide wheel installation area) while minimizing the removal of material from critical load-bearing regions. The channels are configured to follow paths that do not compromise the overall structural integrity of the guide plate.

Inventive Principle:
Principle #3Local quality
