Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing upper valve parts for sanitary fittings require complex mechanisms involving rotatable spindles and multiple disks to control water flow, making them cumbersome and prone to operational issues.
Innovation Solution
A simplified upper valve part design where the spindle's pivoting action controls flow through multiple passage openings, utilizing a control block that can close and open these openings with minimal displacement, facilitated by a spring-loaded mechanism and a seal for robust and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mechanisms with rotatable spindles and multiple disks are used to control water flow, then flow control functionality is achieved, but device complexity increases and operational reliability decreases
Solution Approach 1:
The valve is divided into functionally independent components: a head piece housing, a passage disk with fixed openings, and a movable control block with channels. This segmentation allows each component to perform its specific function simply, avoiding the need for complex interconnected mechanisms while maintaining effective flow control through the interaction of these simple parts.
Solution Approach 2:
The invention extracts and eliminates the rotatable spindle mechanism from the traditional valve design. Instead of using a spindle to rotate disks for flow control, the patent uses a simple movable control block that translates linearly within the head piece, directly opening or closing passages without rotational components.
2Reliability
If traditional rotatable spindle mechanisms are used, then flow control is achieved, but the mechanism becomes prone to operational issues and maintenance problems
Solution Approach 1:
The control block is designed to be self-guided within the head piece through precisely fitted guide surfaces. The block automatically maintains proper alignment and sealing contact with the passage disk through its own geometry and the spring-loaded return mechanism, eliminating the need for external rotational support structures that could fail.
Solution Approach 2:
The invention replaces the mechanical rotational system (spindle and disk rotation) with a simpler translational mechanical system (control block movement). This substitution eliminates bearing surfaces, rotational seals, and complex linkages, resulting in a more reliable mechanism with fewer potential failure points.
3Adaptability or versatility
If multiple disks and rotatable spindles are used for flow control, then switching function is achieved, but ease of operation is reduced due to complex mechanisms
Solution Approach 1:
The control block serves multiple functions simultaneously: it acts as a seal against the passage disk, provides flow control by blocking or opening channels, and indicates valve position through its location. This multi-functionality in a single component achieves switching capability without requiring separate mechanisms for each function.
Solution Approach 2:
Instead of using a rotatable spindle that indirectly controls flow through rotational movement of disks, the invention inverts the approach by using direct linear movement of a control block that physically opens or closes passages. This inversion simplifies the operation from complex rotational control to simple push-pull movement.
