Solution Overview
Problem
Existing vacuum cleaners face challenges in achieving optimal sealing between the waste separation and storage device and the main body, leading to impaired aeraulic performance due to the configuration of the clamping device and elastic return means.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If elastic return means exert pressure on the waste storage container to clamp it in the use position, then the clamping force is improved, but the sealing between the air inlet and connecting duct deteriorates
Solution Approach 1:
The clamping function is segmented into two independent components: the elastic return means provides clamping force through vertical pressure, while the lateral stop provides sealing through horizontal positioning. This segmentation allows each component to optimize its specific function without interfering with the other, resolving the contradiction between clamping force and sealing quality.
Solution Approach 2:
The lateral stop acts as an intermediary element that mediates between the waste storage container and the main body. It provides a dedicated sealing interface that is independent of the elastic return means, enabling the sealing function to be achieved without compromising the clamping force generated by the elastic return means.
2Device complexity
If the waste storage container is clamped directly by elastic return means, then the clamping device is simple, but the aerodynamic performance deteriorates due to poor sealing
Solution Approach 1:
The clamping device is segmented into two functional elements: the elastic return means for clamping and the lateral stop for sealing. This segmentation maintains structural simplicity while improving aerodynamic performance through the dedicated sealing function of the lateral stop, which ensures proper alignment and sealing of the air inlet with the connecting duct.
Solution Approach 2:
The lateral stop is designed to automatically engage and provide sealing when the waste storage container is inserted. This self-service mechanism eliminates the need for complex adjustment mechanisms or additional sealing components, maintaining device simplicity while ensuring optimal sealing for aerodynamic performance.
3Reliability
If the waste storage container pivots around a pivot point formed by the lateral stop and main body, then the sealing of the air inlet is improved, but the device complexity increases
Solution Approach 1:
The pivot function is merged with the lateral stop component. The lateral stop serves dual purposes: it provides the sealing interface for the air inlet and simultaneously acts as the pivot point for the waste storage container. This merging eliminates the need for a separate pivot mechanism, maintaining device simplicity while ensuring reliable sealing.
Solution Approach 2:
The lateral stop is designed as a multi-functional element that performs three functions: (1) provides sealing for the air inlet, (2) acts as the pivot point for the waste storage container, and (3) guides the insertion of the container. This multi-functionality reduces the overall device complexity while achieving reliable sealing.

Implementation Method 2
the waste storage container comprises at least one lateral stop which, when the waste storage container is moved to the position of use, cooperates with the main body to form a pivot point around which the waste storage container pivots under the effect of the pressure exerted by the elastic return means
