Mop Base Kinematic Locking With Retractable Foot Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop base kinematic locking and unlocking systems fail to balance stability, ease of use, and interference-free operation during cleaning, particularly when attaching or detaching the mop for wringing, often causing operational encumbrance and unclear control mechanisms.
Innovation Solution
A kinematic system comprising hinged half-frames with a lever and elastic elements, where the lever is housed within the mop base in the closed state and protrudes for easy foot-operated unlocking, featuring a counter surface groove or tooth to prevent accidental operation, allowing smooth transition between open and closed states without obstructing cleaning or wringing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lever protrudes beyond the mop base profile for easy access, then ease of operation is improved, but the risk of accidental operation and interference during cleaning increases
Solution Approach 1:
The lever dynamically changes its position relative to the mop base profile - it protrudes when the base is open for easy foot access, and retracts within the profile when closed to avoid interference. This dynamic positioning resolves the contradiction between accessibility and safety from accidental operation.
Solution Approach 2:
The counter surface acts as an intermediary mechanism that mediates between the lever and the second half-frame. It provides controlled interference that prevents accidental closing while allowing intentional opening, thus resolving the contradiction by enabling selective interaction.
2Object-affected harmful factors
If the lever is contained within the mop base profile, then interference-free operation is improved, but ease of access for operation deteriorates
Solution Approach 1:
The lever's position is dynamic rather than static - it moves between being contained within the profile (when closed) and protruding beyond it (when open). This dynamic behavior allows the system to optimize for interference-free operation at one state and ease of access at another.
3Ease of operation
If the lever protrudes to enable foot operation, then ease of operation is improved, but the risk of mistaken operation increases
Solution Approach 1:
The counter surface serves as a selective intermediary that allows intentional foot operation (when the lever protrudes and the base is open) while preventing mistaken operation (when the lever is retracted and the base is closed). The counter surface geometry provides this selective permission.
Solution Approach 2:
The counter surface creates preliminary anti-action by positioning geometric features (groove or tooth) that actively prevent the lever from accidentally engaging the second half-frame. This preliminary prevention mechanism stops mistaken operations before they can occur.
4Reliability
If the kinematic system interferes with the second half-frame to prevent return to closed state, then locking reliability is improved, but the complexity of the system increases
Solution Approach 1:
The counter surface acts as a sophisticated intermediary that provides reliable locking through controlled interference. Rather than adding complex locking mechanisms, it uses the geometry of the counter surface (groove or tooth) to create simple yet effective interference that prevents unintended return to the closed state.
