Sweeper Water Tank Release Button Design for One-Handed Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gravity water tanks for sweepers face difficulties in assembly and disassembly, and water filling is inconvenient due to complex processes and the need to turn over the machine body.
Innovation Solution
A water tank design that allows easy mounting and detachment by pulling it in and out from the rear side of the sweeper, featuring a water tank release button for one-handed operation, pivotally mounted components, and ultrasonic welding for reliable coupling, simplifying the assembly and disassembly process without requiring the machine body to be turned over.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a gravity water tank is used for the sweeper, then the cost is low and the structure is simple, but the assembly and disassembly are difficult and water filling is inconvenient
Solution Approach 1:
The water tank incorporates a reset member (spring) that enables dynamic movement of the release button between locked and unlocked states. This dynamic mechanism allows the tank to transition from a fixed, difficult-to-remove state to an easily detachable state, resolving the contradiction between simple structure and easy assembly/disassembly.
Solution Approach 2:
The release button mechanism allows the water tank to be detached through simple user interaction without requiring complex tools or procedures. The spring-loaded button automatically engages and disengages locking features, enabling self-service assembly and disassembly operations.
2Reliability
If the water tank is assembled from the front side of the machine body, then the assembly is secure, but the machine body needs to be turned over for water filling which is inconvenient
Solution Approach 1:
The water tank is inverted in its mounting orientation, with the release button positioned at the bottom of the containing groove rather than at the top. This inversion allows the tank to be securely assembled from the rear side while enabling water filling from the bottom without needing to overturn the machine body, thus resolving the contradiction between assembly security and filling convenience.
3Reliability
If a complex release mechanism is used for the water tank, then the detachment is reliable, but the operation becomes complicated and requires two hands
Solution Approach 1:
The release function is extracted into a dedicated button mechanism that operates independently from the main tank body. This separate, focused release component can be actuated with a simple pressing motion using one hand, while still providing reliable detachment through its connection to the locking mechanism via the spring-loaded reset member.
Solution Approach 2:
The release button changes its operational parameter from requiring complex multi-step manipulation to a simple press-and-release action. The spring mechanism transforms the detachment process into a single-degree-of-freedom motion that can be easily performed with one hand, maintaining reliability while simplifying operation.
