Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices for sanitary equipment face challenges due to varying dimensional tolerances in support elements, leading to oversized fits and complex installation processes.
Innovation Solution
A mounting device with a bearing element clamped between support-side stop surfaces, utilizing resilient tabs to compensate for manufacturing tolerances, ensuring a fixed and secure screw position with zero clearance, simplifying the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bearing parts are configured with sufficiently large clearance to accommodate dimensional variations in support cavities, then the mounting process becomes simple, but the fit becomes always oversized
Solution Approach 1:
The resilient tab is designed to be elastically deformable, allowing it to dynamically adjust its position during insertion and mounting. The tab deflects to accommodate dimensional variations in the support cavity, then returns to its original position to provide a precise fit, combining ease of installation with manufacturing precision
Solution Approach 2:
The resilient tab changes its physical state from a deformed condition during insertion to a recovered condition during mounting. This parameter change allows the tab to adapt to different cavity dimensions during insertion, then provide a consistent, precise fit once mounted
2Ease of manufacture
If dimensional tolerances of support elements are high, then manufacturing is easier, but the bearing element cannot be securely fixed
Solution Approach 1:
The resilient tab provides localized compensation for dimensional variations at the critical interface between the bearing element and support. By concentrating the tolerance compensation function in the resilient tab, the overall support element can be manufactured with higher tolerances while maintaining secure bearing fixation
3Ease of operation
If the bearing element is loosely fitted in the support, then installation is simpler, but the screw position is not fixed
Solution Approach 1:
The resilient tab is pre-configured with elastic properties that enable it to automatically adjust during installation. The tab's elastic deformation during insertion is a preliminary action that prepares it to securely hold the bearing element in the correct position once installed, combining installation simplicity with position stability
