Solution Overview

Problem

Current ice scratchers for snowmobiles are inefficient in directing scratched ice particles towards the snowmobile's components, leading to inadequate cooling and lubrication, especially on icy surfaces where the ice particles are scattered and not effectively utilized.

Innovation Solution

A scratching device with a contacting head and an orienting portion is affixed to the snowmobile, creating a stream of ice particles that are directed towards specific components by the orienting portion, maximizing the amount of ice sent to the components during travel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a traditional ice scratcher is used on icy surfaces, then ice particles are scratched off, but the particles are scattered and not effectively directed towards snowmobile components

Engineering Contradiction:

Improveamount of ice particlesVSAvoideffectiveness of particle direction

Core Design Contradiction:

Quantity of substanceVSEase of manufacture

Solution Approach 1:

The patent introduces a three-dimensional orienting portion (such as a curved surface or angled plate) that redirects ice particles from a scattered two-dimensional pattern into a focused stream directed at snowmobile components. This dimensional transformation of particle trajectory enables effective cooling and lubrication delivery.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The orienting portion acts as an intermediary element between the contacting head and the snowmobile components. It receives ice particles from the scratching action and redirects them toward the target components, serving as a mediating structure that solves the directionality problem.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If ice particles are scattered on icy surfaces, then scratching occurs, but cooling and lubrication of components is inadequate

Engineering Contradiction:

Improvecooling and lubrication effectivenessVSAvoidstructure of scratching device

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device is segmented into distinct functional portions: a contacting head for scratching ice, an orienting portion for directing particles, and a mounting structure for attachment. This segmentation allows each component to perform its specific function optimally while maintaining overall system reliability for cooling and lubrication.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The scratching device serves multiple functions simultaneously: it scratches ice to generate particles, directs those particles toward components, provides cooling through ice particle contact, and delivers lubrication to moving parts. This multi-functionality enhances reliability without proportionally increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If the scratching device directs ice particles towards components, then cooling and lubrication improve, but the device structure becomes more complex

Engineering Contradiction:

Improvecomponent protectionVSAvoiddevice structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The contacting head and orienting portion are merged into an integrated structure where the orienting portion extends from or is attached to the contacting head. This merging reduces the number of separate components and simplifies the overall device structure while maintaining the dual function of scratching and directing ice particles for component protection.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A scratching device and a method for scratching the icy surface for a snowmobile are disclosed. The scratching device, or ice scratcher, comprises a securing portion for laterally attaching the device towards the snowmobile; a scratching portion for scratching an icy surface when the snowmobile is travelling on the icy surface, thereby creating a stream of ice particles; and an orienting component cooperating with the scratching portion for directing the stream of ice particles towards the components of the snowmobile for cooling the components when the snowmobile is travelling. The scratching device may therefore direct, via the orienting component, a stream of ice particles toward the snowmobile components, e.g., for lubrication and cooling. A method of installing the scratching device on the snowmobile is also disclosed.
