Wall Fitting Vandalism Protection via Segmented Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall fittings are insufficiently protected against vandalism, as impacts can cause breaks between the locking plate and the fitting body, leading to leaks and inadequate security.
Innovation Solution
A wall fitting design featuring a connection device with a support element and guide section that provides mechanical support and protection, ensuring the fitting body is securely attached to a bearing part, with a fluidic connection sealed by a sealing element, enhancing resistance to impacts and vandalism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fitting is attached to a thin locking plate with radial play sealed by an O-ring, then the fitting can be supplied with water, but the fitting is insufficiently protected against vandalism and impacts cause breaks between the locking plate and fitting body
Solution Approach 1:
The support element is divided into a front section and a rear section with a guide opening between them. The guide opening receives the guide section of the fitting body, creating a segmented structure that distributes impact forces. This segmentation allows the front section to absorb impacts while the guide opening protects the water connection interface.
Solution Approach 2:
The guide opening acts as a cushioning element positioned before the water connection interface. When impacts occur on the fitting body, the guide section moves within the guide opening, absorbing and dissipating impact energy before it can reach the water connection between the locking plate and fitting body.
2Reliability
If the guide section projects into the guide opening with planar contact, then the fitting body is supported and braced against the support element, but the device complexity increases
Solution Approach 1:
The guide opening serves multiple functions: it provides mechanical support and bracing for the fitting body through planar contact with the guide section, protects the water connection interface from impacts, and guides the fitting body during installation. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The support element combines the front section, rear section, and guide opening into a single integrated component. This merging of functions into one element avoids increasing the number of separate parts while still providing comprehensive support and protection for the fitting body.
