Cleaner Holder Locking Structure for Stable Charging and Battery Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaner holders struggle to stably support and charge vacuum cleaners, particularly due to unstable protruding support pieces that make it difficult to maintain the cleaner in place during charging, and do not prevent battery separation when the cleaner is removed.
Innovation Solution
A cleaner holder with a rotatable locking part and a charging stand that includes a separate fixed member to securely fix both the upper and lower sides of the cleaner, preventing user hand interference and ensuring the battery remains charged even when the cleaner is removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple protruding support piece is used to hold the cleaner, then the device complexity is reduced, but the stability and reliability of cleaner support deteriorates
Solution Approach 1:
The locking part is divided into multiple functional segments: a locking protrusion for engagement, a rotatable body for operation, and a spring mechanism for maintaining locking force. This segmentation allows each component to perform its specific function efficiently while contributing to overall stability without excessive complexity.
Solution Approach 2:
The locking part is designed to be rotatable rather than fixed, allowing it to dynamically transition between locked and unlocked states. The spring mechanism provides dynamic force adjustment to maintain reliable engagement while accommodating variations in cleaner weight and positioning.
2Reliability
If a locking part is added to fix the cleaner, then the cleaner support stability is improved, but the device complexity increases
Solution Approach 1:
Multiple functions are merged into the locking part: it serves as both a support element and a locking mechanism, while also preventing hand insertion. The spring mechanism is integrated within the locking part structure rather than being a separate system, reducing overall device complexity while maintaining reliability.
Solution Approach 2:
The locking part performs multiple functions simultaneously: supporting the cleaner body, preventing cleaner removal, blocking user hand insertion, and providing tactile feedback for locking status. This multi-functionality reduces the need for separate components, balancing reliability improvement with controlled complexity.
3Device complexity
If the locking part is positioned close to the charging stand body, then the device complexity is reduced, but the ease of operation deteriorates due to hand fitting risk
Solution Approach 1:
The design proactively prevents the harmful effect of hand pinching by spacing the locking part away from the charging stand body, creating a safety gap before any manipulation occurs. This preliminary protective measure eliminates the need for additional safety mechanisms while improving ease of operation.
4Ease of operation
If the locking part is spaced apart from the charging stand, then the ease of operation is improved by preventing hand fitting, but the device complexity increases
Solution Approach 1:
The locking part is extracted or separated from the main charging stand body by positioning it on the support piece that extends outward. This spatial separation improves ease of operation by preventing hand pinching, while the support piece serves as the connecting structure, minimizing the increase in overall device complexity.
5Device complexity
If only a single support point is used, then the device complexity is reduced, but the reliability of preventing battery separation deteriorates
Solution Approach 1:
The support system is segmented into multiple support pieces positioned at different locations: one support piece for the cleaner body and another support piece for the battery. This segmentation ensures that when the cleaner is removed, the battery remains independently supported and retained on the charging stand, improving reliability without requiring a complex multi-component system.

AI summary
A cleaner holder includes a first body having a charging terminal to charge a cleaner; a second body connected to the first body, configured to support the cleaner and having an accommodation space in which a battery is accommodated; and a locking part rotatably connected to the first body and configured to fix the cleaner, wherein when force having predetermined magnitude is applied to the locking part in one direction, the locking part is rotated in a first direction to be coupled to the cleaner, so that the cleaner is fixed, and wherein when force having predetermined magnitude is applied to the locking part in the other direction, the locking part is rotated in a second direction opposite to the first direction to be uncoupled from the clean.
