Floor-Cleaning Head Steering Rod for Compact Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held floor cleaning machines lack a compact and efficient steering mechanism, requiring intermediate elements and complicating the design, which hinders ease of operation and maneuverability, especially in tight spaces.
Innovation Solution
A steering rod device articulated on the cleaning head, extending upwards and rearwards, functions as both a push and pull rod, allowing direct pivoting of the cleaning head for directional control without intermediate elements, enabling a compact and ergonomic design with adjustable length and pivotability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a steering rod device articulated on the cleaning head is used, then the steering mechanism becomes compact and direct pivoting is enabled, but the structural complexity increases due to the articulated connection requirements
Solution Approach 1:
The steering rod device combines multiple functions into a single articulated structure that serves as both the steering mechanism and the pivot connection between the cleaning head and chassis. This merging eliminates the need for separate intermediate steering elements, achieving compactness while managing complexity through functional integration.
Solution Approach 2:
The articulated steering rod device performs multiple functions simultaneously: it enables direct pivoting of the cleaning head, provides structural support, and serves as the primary steering control mechanism. This multi-functionality reduces the number of separate components needed, contributing to a compact overall design.
2Ease of operation
If the steering rod device extends upwards and rearwards from the cleaning head, then direct pivoting control is achieved, but the length of the steering rod increases
Solution Approach 1:
The steering rod device extends in multiple dimensions - upwards from the cleaning head and rearwards towards the operator - rather than solely in one direction. This multi-dimensional arrangement enables direct pivoting control while managing the overall length by utilizing vertical and rearward extension instead of purely horizontal length.
3Device complexity
If intermediate elements are eliminated for steering control, then the design becomes compact, but the steering mechanism requires direct articulation which increases structural complexity
Solution Approach 1:
The invention extracts and eliminates intermediate steering elements from the traditional steering mechanism, creating a direct articulation between the cleaning head and the steering rod device. This extraction simplifies the overall design and reduces the volume occupied by the steering mechanism, achieving compactness by removing unnecessary components.
