Solution Overview
Problem
Conventional floor nozzles for vacuum cleaners have a fixed shape, making it difficult to maneuver around obstacles and fit into narrow gaps due to their complex and large design, which limits their versatility and usability in various environments.
Innovation Solution
A vacuum cleaner assembly with a base body that divides into two tubular intake channels, each with a pivotable suction arm that can rotate up to 90 degrees, allowing the nozzle to be folded and inserted into narrow spaces, and a preloading device to maintain the arms in a basic position until needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional floor nozzles are designed with a fixed shape and complex structure, then they provide stable airflow and reliable vacuuming function, but they cannot fit into narrow gaps and are difficult to maneuver around obstacles
Solution Approach 1:
The suction arm is designed to be rotatable relative to the base body, allowing it to dynamically adjust its position and orientation. This enables the floor nozzle to adapt to narrow gaps and obstacles by rotating the suction arm into appropriate angles, while maintaining a relatively simple overall structure when in storage or normal operation position
Solution Approach 2:
The floor nozzle is divided into distinct functional segments: a base body and a separately rotatable suction arm. This segmentation allows the suction arm to be independently positioned and rotated, providing flexibility to access narrow spaces while keeping the main body compact and simple in structure
2Adaptability or versatility
If the suction arm is made rotatable to improve adaptability, then the nozzle can reach into smaller gaps, but the device becomes more complex and may lose stability
Solution Approach 1:
The suction arm incorporates a rotation mechanism that allows it to pivot between a retracted position and extended working positions. This dynamic design enables the arm to rotate into narrow gaps when needed while maintaining structural stability when positioned, resolving the contradiction between adaptability and stability
Solution Approach 2:
The rotation angle of the suction arm is controlled within specific ranges to optimize both adaptability and stability. By limiting the rotation to practical angles needed for accessing gaps and obstacles, the system maintains stability during operation while achieving sufficient versatility

Function Achieved in This Case
The design enables the vacuum cleaner to navigate through tight spaces and obstacles by pivoting the suction arms, providing a more versatile and user-friendly solution for cleaning various surfaces while maintaining stability and airflow efficiency.
Implementation Method 1
the suction arms (9, 10) are held in a home position (15) by means of at least one preloading device (14), wherein the suction arms (9, 10) are pivotable against the force of the preloading device (14) from the home position (15) into pivoting positions (16)... and wherein the suction arms automatically return to their original position by means of the preloading device when no force acts against the preloading device
