Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary inserts require significant space and force for actuation, making them difficult to operate in restricted spaces and necessitating tool-assisted installation and maintenance.
Innovation Solution
A sanitary insert design featuring a pivotable actuation part that transforms lateral load into axial movement through a pivot point, allowing for easy manual installation and operation, with a coupling function for rotation and a force-displacement ratio set by arched surfaces, enhancing user-friendliness and reducing space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a lateral application of load is used to actuate the sanitary insert, then the operating force required by the user is reduced, but a large amount of space is required for the actuation mechanism
Solution Approach 1:
The patent transforms the actuation mechanism from a lateral sliding motion (requiring significant horizontal space) to a rotational motion around a pivot point. The actuation part rotates about a pivot point defined by an abutment, converting lateral application of load into rotational movement that actuates the control element. This dimensional change allows the mechanism to operate with reduced space requirements while maintaining ease of operation.
Solution Approach 2:
The actuation part is designed to be pivotable rather than fixed, allowing it to rotate dynamically around a pivot point. This dynamic capability enables the mechanism to adapt its movement path, transforming lateral force application into effective axial actuation of the control element through rotational motion, thereby reducing the static space requirement.
2Adaptability or versatility
If a pivotable actuation part is used to reduce space requirements, then the structural design possibilities are enhanced, but the force transmission ratio must be carefully controlled
Solution Approach 1:
The patent employs arched surfaces with specific radii of curvature to control the force transmission ratio. The control element interacts with the actuation part through arched surfaces where the radii of curvature are carefully selected to optimize force transmission. By changing the geometric parameters (radii of curvature) of these arched surfaces, the force transmission characteristics are controlled to ensure efficient actuation while maintaining the pivotable design's space advantages.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient operation and tool-free installation in confined spaces, improving user experience and operational efficiency while maintaining mechanical stability and functionality.
Implementation Method 1
the actuation part forms an abutment, which defines a pivot point with respect to a lateral application of load, wherein an operative connection to the control element is created which transforms the lateral application of load into an axial movement
Implementation Method 2
the force transmission ratio or a force-displacement ratio can be set by means of the design of the two mutually touching arched surfaces. This can relate, for example, to the ratio of the two radii of curvature of the touching arched surfaces
