Shrouded Fixation for Ceramic Sanitary Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for mounting ceramic sanitary equipment, such as WC bowls and wash basins, to walls are cumbersome and costly due to the need for complex molding processes and visible fixation systems, which affect manufacturing costs and visual appeal.
Innovation Solution
A ceramic sanitary equipment design that uses a shrouded fixation system with positive draft angles, allowing for high-pressure molding and adhesive attachment, eliminating the need for negative draft angles and visible bolts, and featuring a fixation device with a tapered lug for secure wall engagement without requiring tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wall mounting with visible bolts is used, then secure fixation is achieved, but visual appearance is compromised and installation complexity increases
Solution Approach 1:
The fixation mechanism is extracted from the visible exterior and relocated to the rear end of the sanitary equipment. The rear end itself serves as the mounting surface, eliminating the need for visible bolts and complex installation procedures while maintaining secure fixation.
Solution Approach 2:
The rear end of the sanitary equipment is designed to be self-sufficient as a mounting surface. It includes integrated areas configured to accommodate fixation devices directly on its rear surface, allowing the equipment to mount itself without requiring external support structures or complex installation procedures.
2Device complexity
If shrouded fixation with negative draft angles is used, then concealed mounting is achieved, but manufacturing complexity and cost increase substantially
Solution Approach 1:
Instead of creating negative draft angles in the molding process to achieve shrouded fixation, the invention inverts the approach by designing the rear end with positive draft angles and incorporating fixation areas on the rear surface. This allows the fixation devices to be mounted on the exterior rear surface rather than requiring complex internal molding.
Solution Approach 2:
The fixation areas are pre-configured into the rear end during manufacturing with positive draft angles. This preliminary preparation allows for simple high-pressure molding or casting processes, eliminating the need for complex negative draft angle molding while ensuring proper accommodation of fixation devices.
3Ease of operation
If accessible bolts are used for mounting, then installation is simplified, but visual appearance and cleaning efficiency are compromised
Solution Approach 1:
The mounting function is extracted from the main body of the sanitary equipment and relocated to the rear end. This separation allows the main body to have a continuous, unobstructed surface for efficient cleaning, while the rear end provides the necessary mounting areas for fixation devices.
Solution Approach 2:
The fixation areas are positioned on the rear end surface, utilizing the third dimension (depth/rear surface) rather than requiring access from the top or sides of the equipment. This spatial repositioning eliminates obstructions to cleaning while maintaining installation simplicity.
