Extensible Snowblower Auger Housing for Variable Road Widths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Snowblowers often fail to adapt to varying road widths, either requiring multiple passes or risking damage to adjacent areas due to their fixed lengths.
Innovation Solution
A snowblower with an extensible auger housing and telescopic drive shaft assembly that can configure into compacted and extended lengths, allowing for adjustable auger length to match different road widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the snowblower uses a fixed-length auger housing, then the structure is simple and easy to manufacture, but it cannot adapt to roads of different widths, requiring multiple passes or causing damage to adjacent areas
Solution Approach 1:
The auger housing is divided into multiple telescopic sections that can slide relative to each other along the longitudinal axis. Each section contains an auger member with snow-gathering devices, allowing the housing to extend or retract to match different road widths while maintaining structural integrity and functional continuity.
Solution Approach 2:
The auger housing transitions from a static fixed-length structure to a dynamic telescopic structure that can adjust its length. The telescopic sections with sliding mechanisms enable the housing to change its configuration between extended and retracted states, providing adaptability to varying road widths while preserving operational efficiency.
2Productivity
If the snowblower uses a longer auger housing to cover wider roads in a single pass, then productivity increases, but the snowblower cannot be used on narrower roads without damaging adjacent areas
Solution Approach 1:
The telescopic auger housing allows the snowblower to dynamically adjust its operational width by extending the housing for wide roads to clear snow in a single pass, and retracting the housing for narrow roads to prevent damage to adjacent areas, thus optimizing both productivity and safety across different operating conditions.
Solution Approach 2:
The length of the auger housing is changed as a variable parameter rather than being fixed. By adjusting the extension or retraction of the telescopic sections, the housing length parameter can be optimized for each specific road width, enabling the snowblower to maintain high productivity on wide roads while preventing harmful effects on narrow roads.
3Object-affected harmful factors
If the snowblower uses a shorter auger housing for narrow roads, then damage to adjacent areas is prevented, but multiple passes are required for wide roads, reducing productivity
Solution Approach 1:
The telescopic auger housing provides dynamic length adjustment capability, allowing the operator to extend the housing when working on wide roads to maintain high productivity through single-pass operation, and retract the housing when working on narrow roads to prevent damage to adjacent areas, thus eliminating the need to choose between productivity and damage prevention.

AI summary
A snowblower comprises an auger housing extending along a longitudinal axis and being configurable in a compacted configuration and in an extended configuration wherein a length of the auger housing considered along the longitudinal axis is greater in the at least one extended configuration than in the compacted configuration; and an auger assembly mounted to the auger housing and comprising: a telescopic drive shaft assembly including at least first and second shaft sections slidably mounted to each other to substantially conform to the length of the auger housing in each one of the compacted configuration and the at least one extended configuration; and snow-gathering devices mounted to the at least first and second shaft sections and rotatable therewith.
