Snow Shovel Head Lift Control for Trap Escaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional snow sweepers face inefficiencies and longer detours when trying to escape traps, such as icicles or ground cracks, which leads to reduced effectiveness in snow removal.
Innovation Solution
A trap escaping and snow removal method that includes detecting trigger conditions for trap escaping and performing a preset trap escaping action, which involves adjusting the head-up height of the snow shovel head, determining if the trap escaping condition has been met, and then determining the next snow shoveling position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the snow sweeper returns to the original path to escape a trap, then it can recover from the trapped state, but the detour becomes longer and effectiveness decreases
Solution Approach 1:
Instead of returning to the original path to escape a trap, the patent inverts the approach by adjusting the head-up height of the snow shovel head to lift it off the ground and clear the trap obstacle, allowing the sweeper to continue forward without backtracking
Solution Approach 2:
The patent changes the operational parameter of the snow shovel head by adjusting its head-up height, transforming it from a ground-contact state to a lifted state, which enables the sweeper to escape traps and continue snow removal operations efficiently
2Ease of operation
If the snow sweeper manually adjusts direction to generate machine path, then it can navigate the terrain, but it easily climbs onto snow and skids when bumping into icicles or ground cracks
Solution Approach 1:
The patent applies preliminary action by adjusting the head-up height of the snow shovel head before encountering trap conditions, preventing the sweeper from getting trapped in the first place and maintaining stable movement through potentially problematic terrain

AI summary
A trap escaping and snow removal method includes: performing, when a snow sweeper detects that a current snow shoveling position is in a trigger condition for trap escaping, a corresponding preset trap escaping action, wherein the preset trap escaping action includes the following steps: adjusting a head-up height of a snow shovel head of the snow sweeper at least once; determining, after finishing the preset trap escaping action, whether it is still in the trigger condition for trap escaping; and if not, determining a next snow shoveling position and performing a snow shoveling operation.
