Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiant wall solutions in bathrooms require complex installations and skilled labor, and are either externally mounted or integrated into walls during construction or renovation, limiting versatility and ease of use.
Innovation Solution
A radiant wall panel comprising a thermally insulating support layer with a semi-conductive radiant mat and double-sided adhesive tape, allowing for easy integration into brick or dry walls, with a self-supporting design that can be installed during construction or renovation without expert intervention, and featuring a semi-conductive matrix with conductive particles for efficient heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electric radiant elements are used with exposed external cable and socket connection, then ease of installation is improved, but aesthetic appearance and integration with wall finishing deteriorate
Solution Approach 1:
The patent extracts the cable and socket connection from the visible exterior and relocates them to the interior of the radiant panel. The cable enters through a recess in the rear face, and the socket is mounted on the rear surface, completely hiding external wiring and connections while maintaining ease of installation.
Solution Approach 2:
The patent embeds the cable routing and socket mounting within the panel structure itself. The cable passes through a recess in the rear face and is routed internally, nesting the connection system within the panel's own volume rather than having it external, thus improving aesthetics without complicating installation.
2Use of energy by moving object
If hydraulic bathroom radiators are used, then energy efficiency is improved, but installation complexity and requirement for skilled labor increase
Solution Approach 1:
The patent segments the heating system into self-contained electric radiant panels that can be independently installed on walls without requiring connection to central hydraulic systems. Each panel is a discrete unit with integrated heating elements, eliminating the need for complex plumbing infrastructure and skilled hydraulic installation while maintaining energy efficiency through direct electric heating.
Solution Approach 2:
The radiant panels are designed as self-contained units that can be installed by end-users without requiring connection to building hydraulic systems or intervention by skilled professionals. The panels include all necessary components (heating elements, insulation, cable routing, socket mounting) integrated into a single installable unit that serves itself.
3Ease of operation
If radiant wall panels incorporate exposed cables and sockets, then ease of installation is improved, but adaptability to different wall types and finishing options deteriorates
Solution Approach 1:
The patent designs the panel rear face with a universal recessed cable entry and socket mounting system that can be installed on various wall types (plastered, tiled, drywall). The cable routing and socket placement are integrated into the panel structure itself, allowing the same panel design to adapt to different wall surfaces and finishing options without requiring modification of the connection system.
