Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction devices are limited by their single-cup structure, which restricts 360-degree rotation and is inconvenient to use, especially for devices like satellite navigation systems, and requires specific clamps for different specifications, reducing adaptability.
Innovation Solution
A rotatable multi-cup suction device with two suction cup assemblies connected through a rotatable mechanism, featuring coupling screw rods, air evacuation holes, and hemispherical caps to create negative pressure for enhanced suction and loading capacity, allowing for 360-degree rotation and adaptability across various device specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single suction cup structure is used, then the device is simple in structure, but it cannot achieve 360-degree rotation and has poor adaptability to different device specifications
Solution Approach 1:
The suction device is divided into multiple independent suction cup assemblies (at least two), each capable of independent suction. This segmentation allows each suction cup to be optimized for specific functions while the overall system gains versatility through combination, resolving the contradiction between structural simplicity and adaptability.
Solution Approach 2:
The suction device is designed with multiple suction cup assemblies that can attach to different surfaces and orientations, enabling universal application across various device specifications and mounting scenarios. The rotatable connection assembly further enhances universality by allowing the device to accommodate different angular positions, making a single device adaptable to multiple configurations without requiring device-specific clamps.
2Adaptability or versatility
If a clamp is used to mount satellite navigation devices, then the device can be fixed, but it cannot rotate 360 degrees and requires specific clamps for different specifications
Solution Approach 1:
The connection assembly incorporates a rotatable mechanism that enables dynamic adjustment of the device orientation. This allows the mounted device to rotate 360 degrees and adjust to different angles, transforming a static clamp into a dynamic mounting system that adapts to user needs while maintaining secure fixation.
Solution Approach 2:
Multiple suction cup assemblies are combined with a rotatable connection mechanism into a single integrated mounting system. This merger eliminates the need for separate clamps for different device specifications, as the unified system provides both secure attachment and rotational freedom through its integrated design.
3Adaptability or versatility
If multiple suction cup assemblies are used, then 360-degree rotation and adaptability are achieved, but the device complexity increases
Solution Approach 1:
The suction cup assemblies are designed to be nested or closely integrated through the rotatable connection assembly, with components arranged in a compact configuration. This nesting approach minimizes the overall space occupied by multiple suction cups and reduces the perceived complexity, allowing the multi-component system to function as a cohesive unit rather than a collection of separate parts.
4Strength
If a single suction cup is used, then the structure is simple, but the loading capacity is limited and lifespan is reduced
Solution Approach 1:
The total loading capacity requirement is segmented across multiple suction cup assemblies, with each cup bearing a portion of the total load. This distribution of mechanical stress not only increases the overall loading capacity beyond what a single cup could provide but also reduces wear on each individual cup, thereby extending the system's operational lifespan.

AI summary
A rotatable multi-cup suction device includes at least two suction cup assemblies coupled to each other through a rotatable connection assembly and each including a cup body that is in direct contact with an adhered surface of an object. The cup bodies are each provided with a cap positioned thereon to define a cavity with the cup body. Each of the cup bodies includes a coupling screw rod and each of the caps includes a mounting hole formed in a central portion thereof to receive the coupling screw rod to extend therethrough. Each of the caps is provided, on a top thereof, with a rotary knob that is threadingly coupled to the coupling screw rod and is provided with an air evacuation hole that is connectable to an air evacuation device. Each of the coupling screw rod has a distal end extending beyond an end face of the rotary knob.
