Telescoping Pole Cleaning Tool with Non-Rotatable Nested Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extendable cleaning tools for exterior surfaces, particularly glass surfaces, face challenges in efficiently reaching high locations and maintaining effective cleaning performance, as they often require extensive movement and may not provide customizable lengths or fluid delivery systems efficiently.
Innovation Solution
The design incorporates a telescoping pole configuration with nested pole elements and a working head assembly that includes a water-fed system, allowing for adjustable lengths and fluid delivery to a brush or squeegee, with clamps and connectors that enable secure engagement and rotation, and a pole extension adapter for increased reach without specialized hoses.

Engineering Contradiction Analysis
1Length of moving object
If a telescoping pole configuration is used to reach high locations, then the reach distance is improved, but the device complexity increases due to multiple nested pole elements and clamps
Solution Approach 1:
The pole structure employs nested pole elements where inner pole segments are housed within outer pole segments, allowing the pole to telescope to extended lengths while maintaining a compact form when retracted. This nesting arrangement enables variable reach distance without requiring multiple separate pole sections that would increase complexity.
Solution Approach 2:
The pole is divided into multiple discrete segments or elements that can be independently positioned and locked relative to each other. This segmentation allows the pole to achieve extended lengths through telescoping while each segment remains a manageable component, balancing reach capability with structural simplicity.
2Stability of the object's composition
If the pole elements are made non-circular to prevent rotation, then the stability is improved, but the ease of operation deteriorates due to reduced flexibility in positioning
Solution Approach 1:
The pole elements utilize non-circular cross-sections with asymmetric geometries that prevent rotational movement when engaged. This asymmetric shape ensures that the pole segments can only be positioned in specific orientations, providing stability and preventing unintended rotation during cleaning operations while maintaining ease of assembly through the unique fitting geometry.
3Productivity
If a water-fed working head system is implemented, then the cleaning performance is improved, but the device complexity increases due to fluid delivery requirements
Solution Approach 1:
The water delivery system is merged with the existing pole structure by routing fluid conduits through the hollow interior of the telescoping pole elements. This integration combines the cleaning function with the support structure, eliminating the need for separate external hose arrangements and reducing overall system complexity while maintaining enhanced cleaning performance.
Solution Approach 2:
The pole structure serves multiple functions: it provides mechanical support for the working head, enables telescoping for reach, prevents rotation through non-circular geometry, and simultaneously acts as a conduit for water delivery. This multi-functionality reduces the need for additional separate components, thereby improving cleaning performance without proportionally increasing device complexity.
