Retractable Nested-Housing Heater to Reduce Storage Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heaters with large structural sizes occupy significant space and are inconvenient for storage when not in use.
Innovation Solution
A retractable heater design featuring a housing assembly with nested installation housings that form a heat dissipation channel, allowing the heater to be compactly stored by sliding one housing into another, with a heating assembly placed inside the channel and air inlets and outlets strategically positioned for efficient heat dissipation and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heater uses a large structural size, then the heat dissipation effect is improved, but the storage space occupation increases and portability deteriorates
Solution Approach 1:
The housing assembly is designed with retractable sections that can dynamically change between extended and retracted states. The housing includes an inner housing and an outer housing that can slide relative to each other, allowing the heater to transform from a compact storage state to an extended operational state, thus resolving the contradiction between large operational size and small storage volume
Solution Approach 2:
The heater employs a nested housing structure where the inner housing is placed inside the outer housing. When retracted, the inner housing fits within the outer housing, creating a compact form factor for storage. When extended, the inner housing pulls out to form the operational heating structure, effectively reducing storage volume while maintaining heat dissipation performance
2Productivity
If the heater structure is extended to form a high tower structure, then the heat dissipation channel is formed and heating efficiency is improved, but the storage convenience deteriorates
Solution Approach 1:
The housing assembly incorporates movable sections that can be easily extended and retracted. The inner housing slides within the outer housing along guiding rails, allowing users to quickly transform the heater between compact storage mode and extended heating mode, thereby improving storage convenience without compromising heating efficiency
Solution Approach 2:
The housing is divided into multiple separable sections (inner housing and outer housing) that can independently move relative to each other. This segmentation allows the heater to be compacted into a small storage form by nesting the inner section within the outer section, while still forming an effective heat dissipation channel when extended
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design reduces storage volume, enhances portability, and minimizes safety risks by allowing the heater to be extended into a high tower structure for use while maintaining compactness for storage, ensuring efficient heat dissipation and user safety.
Implementation Method 1
The heating assembly includes a heating wire provided around the circumference of the heat dissipation channel
Implementation Method 2
when the housing assembly is extended, interiors of the housing assemblies communicate with each other to form a heat dissipation channel... the installation housing located at a bottom of the housing assembly is provided with an air inlet, and the installation housing located at a top of the housing assembly is provided with a heat dissipation port
