Telescopic Window Cleaner With Manual Pumped Liquid Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window cleaning implements are hindered by the need for external drums or electric pumps, which restrict operator mobility and lead to wastage of cleaning liquid due to lack of calibrated dispensing.
Innovation Solution
A manually operated window cleaning implement with a detachable reservoir and a self-priming, manually activated pump that dispenses washing liquid in calibrated quantities through a flexible hose and nozzle system, allowing for easy movement and efficient cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If an external drum or electric pump is used to supply washing liquid, then the liquid can be distributed continuously, but the operator's mobility is restricted and the device complexity increases
Solution Approach 1:
The washing liquid reservoir is extracted from the main implement body and made detachable, allowing the operator to carry only the necessary components. The reservoir can be removed and replaced independently, enabling the operator to move freely without being constrained by a large integrated drum structure.
Solution Approach 2:
The implement is divided into separate functional modules: a detachable reservoir, a manual pump mechanism, a flexible hose system, and the cleaning head. This segmentation allows each component to be optimized independently and enables the operator to carry only the essential parts, greatly improving mobility.
2Device complexity
If a manual sprayer system is used, then the device complexity is reduced and portability is improved, but the liquid dispensing cannot be calibrated leading to wastage
Solution Approach 1:
The manual pump mechanism is designed to be operated directly by the user through a simple hand-operated lever or piston system. The user controls the pumping action and liquid flow rate, enabling calibrated dispensing according to actual cleaning needs without requiring complex automated dosing systems.
Solution Approach 2:
A manual pump mechanism is incorporated into the detachable reservoir assembly to provide controlled hydraulic delivery of washing liquid through a flexible hose. This allows calibrated liquid transfer from the reservoir to the cleaning head, enabling precise dosing without complex electronic controls.
3Length of moving object
If a telescopic pole with swivel head and integrated pump is used, then the cleaning reach is extended, but the weight increases and freedom of movement is conditioned
Solution Approach 1:
The implement uses a telescopic pole structure that can be extended or retracted as needed, allowing the operator to adjust the cleaning reach dynamically. The pole segments connect through telescopic joints that maintain structural integrity while enabling compact storage and reduced weight when fully retracted.
Solution Approach 2:
A flexible hose replaces rigid piping to connect the detachable reservoir to the cleaning head. This flexible connection allows the hose to accommodate the telescopic pole's movement and the swivel head's rotation without adding significant weight or restricting the operator's freedom of movement.

AI summary
A window cleaning implement (10) comprises a tubular body divided into rear (12) and front (14) segments inserted telescopically one inside the other and connected by a threaded ring nut (16); the front segment supports a cleaning head (24) fitted with hooking devices for a cloth in microfiber or other suitable material. Said implement comprises, in addition, a removable reservoir (20) for the washing liquid which is drawn from it by means of a manual pump incorporated in said implement, channelled along a flexible hose (32) and dispensed through at least one nozzle (30) placed next to said cleaning head (24).
