Vacuum Cleaner Charging Base Connector Pivoting Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing charging bases for vacuum cleaners are complex and tedious to assemble, requiring multiple steps and are costly to manufacture, with a risk of inadvertent disassembly and movement of electrical connectors during charging.
Innovation Solution
A charging base with a support body fixed to a wall, featuring a locking member that allows easy and reliable assembly of the male electrical connector, reducing manufacturing costs and preventing inadvertent disassembly, by allowing angular pivoting and translation locking of the connector within the insertion housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the male electrical connector is fixed in a low-height insertion housing via a rear face passage opening, then the height requirement of the support body is limited, but the assembly process becomes complex and tedious requiring multiple positioning and tilting steps
Solution Approach 1:
The male electrical connector is designed with angular adjustability, allowing it to pivot between a first angular orientation during insertion and a second angular orientation for final positioning. This dynamic adjustment capability enables the connector to adapt to the insertion housing geometry without requiring complex manual positioning steps, thereby simplifying the assembly process while maintaining compact dimensions
Solution Approach 2:
The locking member is pre-configured to automatically engage with the male electrical connector during the insertion process. This preliminary action of the locking mechanism guides the connector into the correct position and secures it without requiring separate positioning and securing steps, reducing assembly complexity while preserving the compact low-height design
2Length of stationary object
If the male electrical connector is inserted through a rear face passage opening in a low-height insertion housing, then the support body height is minimized, but the risk of inadvertent disassembly and movement of the connector increases
Solution Approach 1:
The male electrical connector incorporates angular adjustability with a locking mechanism that transitions the connector from a movable state during insertion to a locked state in the final position. This dynamic design allows the connector to be securely fixed at different angular orientations, preventing inadvertent disassembly and movement while maintaining the compact low-height structure
Solution Approach 2:
The locking member acts as an intermediary element between the male electrical connector and the insertion housing. It provides a mechanical interlocking mechanism that secures the connector in place, preventing both disassembly and movement during charging operations, while allowing the overall support body to maintain minimized height
