Solution Overview

Problem

Existing snow throwers require manual preheating in cold environments, which is time-consuming and inconvenient for users due to the need to wear thick clothing and handle the device outdoors.

Innovation Solution

A snow thrower equipped with a wireless communication system allows remote preheating of key components through a control module, enabling users to initiate heating from a distance, reducing outdoor wait times and enhancing usability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual preheating is performed in cold environments, then the snow thrower can be operated, but the user experiences prolonged exposure to cold conditions and time-consuming preparation

Engineering Contradiction:
Improvepreheating convenienceVSAvoidpreheating time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preheating action before the user needs to operate the snow thrower. The user can remotely activate the heating element through wireless communication, and the system begins heating the handle and body components in advance, so when the user arrives, the device is already warmed up and ready for operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A wireless communication module acts as an intermediary between the user's mobile device and the snow thrower's control system. The user sends a preheating command via wireless signal, which the control module receives and executes, allowing remote operation without direct physical contact or prolonged outdoor exposure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Temperature

If the user waits outdoors for preheating, then the snow thrower reaches operating temperature, but the user's comfort deteriorates due to cold exposure

Engineering Contradiction:
Improvesnow thrower temperatureVSAvoidcold environment exposure
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The wireless communication module serves as an intermediary that allows the user to initiate preheating from a distance. The user can trigger the heating function before approaching the snow thrower, eliminating the need to stand in the cold waiting for the device to warm up.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The snow thrower performs self-heating through integrated heating elements controlled by the control module. Once activated remotely, the system automatically heats its own components (handle, body) without requiring continuous user supervision or presence in the cold environment.

Inventive Principle:
Principle #25Self-service
