Angled piece for fixing toilets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing angled pieces for fixing toilets to the ground face issues with alignment due to a large lateral area without holes, leading to potential misalignment and crossed threading during assembly.
Innovation Solution
The angled piece features a plurality of cavities with decreasing cross-sections arranged in columns, acting as a guide for the screw, and includes blind holes to increase the attachment area, preventing misalignment and ensuring a secure fixation by forming a solid part that allows the screw to drill into the toilet base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a plurality of holes are provided in the base for easier assembly, then the ease of operation is improved, but the lateral area without holes increases leading to misalignment and crossed threading
Solution Approach 1:
The base is segmented into multiple functional zones: a first area with a plurality of holes for screw passage, and a second area with guide cavities. This segmentation allows the holes to be arranged for ease of assembly while the guide cavities provide alignment precision, resolving the contradiction between ease of operation and manufacturing precision.
Solution Approach 2:
Guide cavities act as an intermediary element between the holes and the screw. These cavities receive and guide the screw during assembly, ensuring proper alignment before the screw engages with the holes. This intermediary structure eliminates misalignment issues while maintaining the benefits of multiple holes for ease of assembly.
2Strength
If the cavities are blind holes, then the attachment area is increased for more resistant fixation, but the manufacturing complexity increases
Solution Approach 1:
The blind holes are pre-formed in the base during manufacturing, creating the guidance structure in advance. This preliminary action allows the holes to be precisely positioned and shaped to provide both alignment guidance and enhanced fixation strength, while the manufacturing complexity is managed through integrated mold design.
Solution Approach 2:
The base is made of a material that combines ease of molding for complex blind hole geometries with sufficient strength for fixation. This composite approach allows the creation of blind holes with decreasing cross-section that provide both guidance and enhanced attachment area, resolving the contradiction between manufacturing ease and fixation strength.
