Dual-Charging Cleaner Holder With Guided Battery Docking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner holders cannot simultaneously charge both the cleaner body and its detachable battery, leading to user inconvenience due to frequent battery discharge during cleaning.
Innovation Solution
A cleaner holder design featuring a first body with a charging port for the cleaner and a second body with a recessed battery accommodating space, including a second charging port, allows for simultaneous charging of the cleaner and its detachable battery, with a cleaner guide ensuring proper terminal contact and stable holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the holder only charges the cleaner body, then the charging structure is simple, but the battery cannot be separately charged causing user inconvenience
Solution Approach 1:
The holder is designed to perform multiple functions: it can charge both the cleaner body (via the cleaner receiving cavity with first charging port) and the detachable battery independently (via the battery receiving cavity with second charging port). This multi-functional design resolves the contradiction by enabling versatile charging capability while maintaining a unified, integrated holder structure rather than requiring separate charging devices.
Solution Approach 2:
The holder is divided into functionally independent segments: a cleaner receiving cavity for holding and charging the cleaner body, and a battery receiving cavity for holding and charging the detachable battery. Each cavity has its own charging port and terminal contact mechanism. This segmentation allows independent charging of either component without interfering with the other, resolving the versatility-complexity contradiction.
2Adaptability or versatility
If the holder accommodates both cleaner and battery, then charging versatility improves, but the holder size increases
Solution Approach 1:
The battery receiving cavity is positioned within or adjacent to the cleaner receiving cavity in a nested or integrated arrangement. The battery cavity utilizes the vertical or lateral space efficiently, allowing the battery to be stored and charged within the overall holder footprint without requiring a completely separate charging station. This nesting approach minimizes the total area occupied while providing dual charging capability.
3Adaptability or versatility
If the holder supports cleaners with upper-side centers, then compatibility improves, but the holding structure becomes more complex
Solution Approach 1:
A cleaner guide structure acts as an intermediary component between the cleaner body and the holder. The guide includes guiding surfaces that direct and position the cleaner body, ensuring proper alignment of the charging terminal with the first charging port. This intermediary guiding mechanism enables compatibility with various cleaner types (including those with upper-side centers) without requiring complex adjustable support structures, as the guide passively directs the cleaner into the correct position.
4Reliability
If the cleaner guide ensures precise terminal contact, then charging reliability improves, but the guide structure complexity increases
Solution Approach 1:
The cleaner guide structure utilizes the weight and geometry of the cleaner body itself to achieve proper alignment. As the cleaner is placed into the holder, gravity and the guiding surfaces work together to automatically position the cleaner's charging terminal in contact with the first charging port. This self-aligning mechanism achieves reliable terminal contact without requiring complex active adjustment devices, motors, or sensors, thereby maintaining structural simplicity while ensuring charging reliability.
