Rotatable Vacuum Cleaner Cover Hinge for Open-State Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face challenges in maintaining the open state of the dust collection part cover due to self-weight closure and inertia forces, which can lead to unintended closure and movement of the cleaner body.
Innovation Solution
A vacuum cleaner design featuring a rotatable cover with a hinge mechanism and an opening maintenance unit, including elastic members and support structures, that automatically maintains the cover in an open position using elastic forces and guide grooves to prevent closure and ensure easy dust container mounting and separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dust collection part cover is made freely openable and closable, then ease of operation is improved, but the cover cannot be maintained in the opened state and closes due to self-weight
Solution Approach 1:
The biasing means applies a preliminary force in the opening direction to counteract the self-weight closure tendency of the cover, enabling the cover to be maintained in the opened state without requiring external support
Solution Approach 2:
The biasing means is integrated into the cover assembly to automatically maintain the cover in the opened state through elastic biasing force, eliminating the need for external support structures
2Ease of operation
If the dust collection part cover is opened, then access to the dust collection chamber is improved, but the cleaner main body moves due to inertia force
Solution Approach 1:
The counterweight mechanism generates an opposing force to balance the inertia force produced when the cover is opened, preventing the cleaner main body from moving or turning over during the opening operation
3Reliability
If a complex opening maintenance unit is added to maintain the cover in open state, then cover position stability is improved, but device complexity increases
Solution Approach 1:
The biasing means is integrated into the cover assembly to automatically maintain the cover in the opened state through elastic biasing force, eliminating the need for external support structures
Solution Approach 2:
The opening maintenance function is extracted as a separate biasing means component that can be independently designed and integrated, simplifying the overall system architecture
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively maintains the dust collection part cover in an open state, preventing unintended closure and facilitating easy operation by using elastic forces to keep the cover rotated, thus enhancing user convenience and preventing interference with the power transmission part.
Implementation Method 1
The first opening maintenance part may include an elastic member elastically supporting the hinge mechanism
