Spring-Loaded Mop Plate Wing Release to Prevent Re-Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop plates with foot pedal-actuated fixing devices often result in the mop plate wings remaining in the working position and re-locking after the foot pedal is released, requiring additional components like spring elements to pivot into the wringing position, which complicates the transition between positions.
Innovation Solution
The design incorporates a spring-loaded foot pedal that allows the second mop plate wing to pivot relative to the first when actuated, preventing automatic re-locking, and uses snap connections or projections to ensure the wings remain unlocked after releasing, with the foot pedal's design ensuring automatic locking when transitioning back to the working position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a foot pedal-actuated fixing device is used to lock the wiper plate wings in the working position, then the wings can be securely fixed during operation, but the wings tend to remain in the working position and re-lock after the foot pedal is released, requiring additional spring components to pivot into the wringing position
Solution Approach 1:
The foot pedal is designed to automatically return to its initial position after actuation through its own elastic deformation characteristics, without requiring additional spring components. The pedal's structure enables it to self-reset and release the locking mechanism, allowing the wiper plate wings to pivot to the wringing position naturally.
Solution Approach 2:
The invention removes the unnecessary spring component from the system by designing the foot pedal itself to provide the required elastic function. This extraction of the redundant component simplifies the overall device structure while maintaining the locking and releasing functionality.
2Ease of operation
If spring elements are added to pivot the wiper blades into the wringing position after foot pedal release, then the blades can be moved from working position, but the device becomes more complex and manufacturing cost increases
Solution Approach 1:
The foot pedal is designed to perform multiple functions: it acts as both the locking mechanism actuator and the releasing mechanism. By integrating the elastic return function directly into the pedal structure, it eliminates the need for separate spring components, thereby simplifying manufacturing while maintaining ease of operation.
Solution Approach 2:
The invention combines the locking release function and the position-changing function into a single integrated foot pedal structure. The pedal's elastic deformation and return motion are merged with the wing pivoting mechanism, eliminating the need for separate components and simplifying the overall system.
3Device complexity
If the foot pedal actuation direction corresponds to the pivot direction of the wiper blades, then the structure is simplified, but the wiper blades may remain in working position or lock back after pedal release
Solution Approach 1:
The foot pedal is designed with dynamic elastic characteristics that enable it to deform during actuation and automatically return to its initial position after release. This dynamic behavior ensures that the locking mechanism is reliably released and the wiper blades can pivot to the wringing position without remaining stuck or locking back.
Solution Approach 2:
The foot pedal is pre-designed with built-in elastic return capability, so that upon release it automatically returns to its initial position before the wiper blades can lock back. This preliminary preparation of the pedal's elastic state prevents the blades from re-locking and ensures reliable position transition.
