Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tile leveling structures rely on operator experience for positioning, leading to uneven tile flatness and require significant manual force, risking occupational injuries.
Innovation Solution
A tile leveling structure with a support base and a pressing seat featuring ratchet teeth and an elastic pressing seat made of plastic material, allowing for precise leveling and reduced manual effort through interlocking ratchet mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the wedge is manually pushed by the operator to press the tiles, then the tiles can be leveled, but the operator has to exert a larger force which causes occupational injury
Solution Approach 1:
The wedge is designed with a ratchet mechanism that allows it to automatically lock into the base at predetermined positions without requiring the operator to manually push it into place. The elastic pressing seat further assists by automatically pressing the wedge into the base when the leveling head is pressed down, eliminating the need for the operator to exert large forces on the press portion.
Solution Approach 2:
The elastic pressing seat acts as an intermediary between the operator's pressing action and the wedge. When the operator presses the leveling head, the elastic pressing seat converts this force to push the wedge into the base, distributing the force and reducing the direct manual effort required on the press portion.
2Device complexity
If the wedge position is determined by operator experience, then the structure is simple, but the flatness of the tiles is not uniform
Solution Approach 1:
The base is pre-equipped with through holes at predetermined positions, and the wedge is designed with ratchet teeth that correspond to these holes. This preliminary arrangement of positioning features eliminates the need for operator judgment during operation, ensuring uniform tile flatness while maintaining structural simplicity.
Solution Approach 2:
The ratchet mechanism on the wedge automatically engages with the through holes in the base, allowing the wedge to self-position at the correct location without requiring operator experience or judgment. This self-positioning feature ensures consistent tile leveling across different operators.
3Manufacturing precision
If the press portion is designed to force the wedge into the base, then the leveling function is achieved, but the operator's finger is easily hurt during long-term operation
Solution Approach 1:
The elastic pressing seat automatically pushes the wedge into the base when the leveling head is pressed down, eliminating the need for the operator to continuously press the press portion. This self-actuating mechanism reduces repetitive manual effort and associated finger injuries.
Solution Approach 2:
The elastic pressing seat serves as a mediator that converts the operator's pressing motion on the leveling head into the force needed to insert the wedge into the base. This intermediary mechanism distributes the force over a larger area and reduces the direct pressure on the operator's finger.
