Toilet Connection Frame With Offset Guide Tube for Smart Retrofit Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices between flush-mounted water boxes and flushing toilets are not user-friendly for pipe laying and wiring, especially when converting a conventional toilet to an intelligent one, due to limited space for water and cable connections behind the ceramic wall for wastewater release.
Innovation Solution
A connecting device featuring a fastening frame with vertically arranged columns, an assembly plate, a flushing tube, a sewage pipe, and a guide tube that allows for separate laying of cables or water pipes, with the guide tube's lower end offset from the central axis to avoid interference with the wastewater release, facilitating easier installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional connection devices are used with pre-routed water pipes and wiring, then the structure is simple, but the ease of operation for pipe laying and wiring deteriorates due to limited space behind the ceramic wall
Solution Approach 1:
The connection device is divided into separate functional modules: a fastening frame for structural support, a guide pipe for cable routing, and a mounting plate for toilet attachment. This segmentation allows each component to be optimized independently, with the guide pipe providing a dedicated pathway for wiring that simplifies installation while maintaining overall structural efficiency
Solution Approach 2:
The guide pipe acts as an intermediary element between the wall opening and the toilet, providing a protected and organized pathway for cables. This intermediary structure eliminates the need for complex routing behind the ceramic wall, as cables can be easily fed through the guide pipe's opening that protrudes forward
2Ease of operation
If the lower end of the guide pipe is positioned on the central axis, then the structure is symmetric and simple, but it interferes with the wastewater outlet of the toilet
Solution Approach 1:
The guide pipe is intentionally positioned asymmetrically, with its lower end offset from the central axis of the fastening frame. This asymmetric placement strategically positions the guide pipe opening to the side, avoiding interference with the centrally located wastewater outlet while still providing easy access for cable routing during installation
3Adaptability or versatility
If conversion from conventional toilet to smart toilet is performed, then intelligent functions are added, but the difficulty of detecting and measuring increases due to routing problems of water and cable lines
Solution Approach 1:
The connection device is designed with universal applicability for both conventional and smart toilet conversions. The guide pipe structure provides a standardized cable routing solution that works regardless of the toilet type, while the separate fastening frame and mounting plate configuration allows the same device to serve traditional flush toilets as well as modern smart toilets with additional wiring requirements

AI summary
The invention relates to a connecting device between a concealed cistern and a flush toilet, comprising a mounting frame (10) with two vertically arranged columns (12) positioned on the left and right. The connecting device further includes a mounting plate (14) for horizontally connecting the left and right columns (12), on which mounting holes (142) are provided for mounting the flush toilet, a flush pipe (20) for connecting the concealed cistern to a flush line of the flush toilet, and a waste pipe (30) for connecting to a waste drain of the flush toilet. The connecting device according to the invention is characterized by a guide tube (40), the interior of which is used for routing cables or water pipes. The upper end of the guide tube (40) communicates with the concealed cistern.The lower end of the guide tube (40) is located below the inlet opening of the wastewater pipe (30) and is positioned off-center from the central axis (A), which bisects the mounting frame (10) on the left and right. The guide tube (40) allows the cables and/or water pipes to be routed separately.
