Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile heating devices struggle to maintain lower temperatures in peripheral zones that come into contact with users, particularly children, while efficiently heating large rooms, and lack effective accident-prevention and aesthetic features.
Innovation Solution
The mobile heating device incorporates heat-insulating covering means made of elastomer or thermoplastic materials that cover peripheral zones, providing a lower temperature and preventing direct contact, while allowing efficient room heating and incorporating accident-prevention and aesthetic design elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heat-dissipating geometries (bends or fins) are made directly in the peripheral zones of the plates, then heat transmission efficiency is improved, but the temperature in peripheral zones remains too high causing burn risks to users
Solution Approach 1:
The patent introduces an intermediary substance (heat-insulating material) between the hot peripheral zones of the radiator plates and the user's body. This intermediary layer blocks heat transfer while allowing the radiator to maintain its heat-dissipating geometries for efficient heating. The covering means acts as a mediator that separates the useful function (heat transmission to room) from the harmful effect (burn risk to users).
Solution Approach 2:
The patent employs flexible covering means in the form of thin films or shells made of heat-insulating materials that conform to the peripheral zones of the radiator plates. These flexible coverings effectively isolate the hot surfaces from user contact while maintaining the underlying heat-dissipating geometries. The thin film approach provides adequate insulation without significantly increasing device complexity.
2Shape
If covering plates are mounted in front of the edge of each single module for aesthetic reasons, then appearance is improved, but the covering plates are fixed with screws and rivets which may affect heat transmission and increase device complexity
Solution Approach 1:
The patent extracts the fastening elements (screws and rivets) from the design by using alternative attachment methods. The covering means are fixed to the radiator modules using adhesive substances or elastic retention mechanisms, eliminating the need for mechanical fasteners like screws and rivets. This extraction simplifies the device while maintaining aesthetic appearance and avoiding interference with heat transmission.
Solution Approach 2:
The patent replaces the mechanical fastening system (screws and rivets) with non-mechanical attachment methods such as adhesive substances or elastic retention. This substitution eliminates the complexity associated with mechanical fasteners while achieving the same functional goal of securing the covering plates. The replacement also avoids creating thermal barriers that could interfere with heat transmission.

AI summary
A mobile device for heating rooms, comprising radiant elements, each provided with two heat-conductor plates associated with each other to define a central portion and connected fluid-dynamically with each other by means of connection elements. A heated heat-carrying fluid is able to flow in the central portions and, through the connection elements, from one to the other of the radiant elements in order to heat the surrounding room. Each pair of heat-conductor plates comprises lateral walls which are distanced from the corresponding central portion so as to define respective peripheral zones. The mobile device also comprises heat-insulating elements able to be applied due to having substantially the same shape so as to cover at least a part of the peripheral zones of the lateral walls.
