Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaner nozzles lack versatility in adapting to different surfaces, requiring additional mechanisms like configurable wheels for multiple modes of operation, which complicates the cleaning process.
Innovation Solution
A vacuum cleaner nozzle with a retractable brush and a spring-loaded glide plate that can be moved vertically to enable three modes of operation: hard floor, carpet, and a multi-functional mode, allowing efficient cleaning on various surfaces without additional arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional nozzles use additional mechanisms like configurable wheels for multiple modes of operation, then versatility in adapting to different surfaces is improved, but device complexity increases
Solution Approach 1:
The patent combines the functions of brush movement and glide plate positioning into a single integrated mechanism. The selector switch controls both the brush retraction/extension and the glide plate movement simultaneously, merging what would traditionally require separate mechanisms into one unified system that achieves multi-surface adaptability without proportional increase in complexity
Solution Approach 2:
The glide plate serves multiple functions: it acts as a support element for carpet cleaning, a floating element for hard floor cleaning, and works in conjunction with the brush for combination modes. This multi-functionality allows a single component to replace what would traditionally require multiple specialized mechanisms for different cleaning modes
2Adaptability or versatility
If the brush and glide plate are moved vertically to enable multiple modes of operation, then adaptability to different surfaces is improved, but ease of operation may worsen due to manual adjustment requirements
Solution Approach 1:
The system incorporates a spring-loaded glide plate that automatically adjusts its position based on the surface type detected by the user's selection. When the selector is set to a particular mode, the spring mechanism self-adjusts the glide plate to the appropriate position without requiring manual intervention, making the operation as simple as switching modes rather than manually adjusting multiple components

Function Achieved in This Case
Enables efficient and quiet operation on different surfaces by allowing the brush and glide plate to be positioned optimally, reducing noise and increasing suction power, while allowing for easy mode selection using a top-mounted selector.
Implementation Method 1

AI summary
The invention relates to a vacuum cleaner nozzle with a nozzle head (103) having at least one suction opening through which suction opening air can enter the vacuum cleaner nozzle. The vacuum cleaner nozzle also comprises at least one movable glide plate (108) configured to in at least one mode of operation glide on a surface to be cleaned and at least one retractable brush (109). The vacuum cleaner nozzle is configured to be selectable operated in at least three modes of operation. Each of the at least three modes of operation are enabled by moving the at least one of the retractable brush and the at least one glide plate in relation the nozzle head. The movement will typically be vertical when the nozzle head is used on a horizontal surface. Hereby multiple modes of operations are enabled in an efficient manner that can provide different modes of operation suitable for different surfaces. The different modes of operations can be enabled by only moving a retractable brush and a glide plate. Hence there is no need for any additional arrangement such as configurable wheels for providing multiple (at least three) modes of operation.
