Solution Overview
Problem
Existing electric heating devices with integrated batteries face issues such as reduced battery lifespan due to heat confinement, complex and costly industrialization, and inefficient heat dissipation, which affect performance and longevity.
Innovation Solution
The design incorporates an air inlet at the lower part of the casing and an air outlet at the upper part, allowing air to circulate through the device, with the electrical energy storage device positioned between the air inlet and heating element, promoting natural convection and direct thermal contact between electrochemical cells and air, thereby enhancing heat transfer and reducing internal heat losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective casing is used for the battery, then the battery is protected and can be handled as a single block, but the heat produced by the battery is confined leading to increased internal temperature and reduced battery lifespan
Solution Approach 1:
The patent removes the protective casing from the battery, extracting the heat confinement problem. The battery is installed directly in the air flow path without an enclosing protective envelope, allowing heat to be carried away by the circulating air rather than being trapped inside a insulated casing.
Solution Approach 2:
The patent uses the air flow (pneumatic system) to cool the battery. The circulating air acts as a cooling medium that absorbs heat from the battery cells as it passes through the device, replacing the need for a protective casing with a passive convective cooling mechanism.
2Loss of energy
If a protective casing with thermal insulation is used for the battery, then the battery is protected, but the heat produced by the battery is delayed in being valued for heat production
Solution Approach 1:
The protective casing that causes heat transfer delay is removed. The battery is exposed directly to the air flow, eliminating the insulating barrier that would delay heat transfer from the battery to the surrounding air.
Solution Approach 2:
The air flow serves dual purposes: it provides cooling for the battery and simultaneously serves as the heat transfer medium for heating the room. The heat produced by the battery is immediately transferred to the circulating air, which then distributes it throughout the space.
3Ease of manufacture
If a protective casing is used for the battery, then the battery assembly can be handled as a single block, but the industrialization of the heating device becomes substantially complex and expensive
Solution Approach 1:
The protective casing is extracted from the design, simplifying the manufacturing process. Without the need to produce, assemble, and install a separate protective envelope around the battery, the manufacturing complexity and costs are reduced.
Solution Approach 2:
The battery mounting is integrated directly into the housing structure. The battery is installed in a recess or dedicated space within the housing, eliminating the need for a separate protective casing and reducing the number of components and assembly steps.
