Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transportable saunas face challenges such as laborious disassembly and reassembly, structural weaknesses, inadequate performance in cold weather, and water buildup due to uneven ground installation, which limit their usability on various surfaces and environments.
Innovation Solution
A transportable sauna with a prefabricated wooden frame and adjustable leg arrangement made of cross-laminated timber, allowing for height adjustment and use on uneven surfaces, along with a drainage system to prevent water accumulation, and the ability to be transported without full disassembly, utilizing a metal leg structure for stability and a sloping floor for water drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sauna is made transportable, then it can be moved to different locations, but it requires complete disassembly and reassembly which is laborious
Solution Approach 1:
The sauna is divided into separate modular components including wall panels, floor sections, and roof elements that can be independently handled. The wall panels are further segmented with integrated framing members that allow for tool-free connection, enabling quick assembly and disassembly without requiring complete breakdown of structural integrity
Solution Approach 2:
The sauna incorporates adjustable and detachable leg arrangements that can be quickly configured or removed. The leg height is adjustable to accommodate uneven ground surfaces, and the entire leg assembly can be detached for transport without affecting the main structure, making the sauna dynamically adaptable to different installation conditions
2Stability of the object's composition
If the sauna uses a fixed wall structure, then it provides structural stability, but it performs insufficiently in cold weather conditions
Solution Approach 1:
The wall structure employs composite construction combining wooden framing members with insulation panels and outer cladding. The cross-laminated timber (CLT) floor and base element provide structural stability while the multi-layer wall construction incorporates thermal insulation layers that maintain interior temperatures in cold weather, achieving both structural integrity and thermal performance
Solution Approach 2:
The sauna implements differentiated insulation strategies in different locations. The base element and floor structure include integrated insulation layers to prevent heat loss to the ground, while wall panels incorporate insulation cores. The leg arrangements extend below ground level to provide additional thermal barrier, creating local quality improvements where heat loss is most critical
3Adaptability or versatility
If the sauna is installed on uneven ground, then it can be placed on various terrains, but water builds up inside causing damage
Solution Approach 1:
The adjustable leg arrangements allow the sauna to be dynamically positioned on uneven ground surfaces. Each leg can be independently adjusted in height to compensate for ground irregularities, and the legs can be detached entirely for transport. This dynamic adjustment capability enables installation on various terrains while maintaining proper drainage angles to prevent water accumulation
Solution Approach 2:
The sauna base element is designed with a sloped configuration that redirects water flow toward drainage openings. The floor structure incorporates a longitudinal slope that channels rainwater and condensation toward designated drainage points at the perimeter, preventing water buildup in the interior space by utilizing gravitational flow in another dimension
4Object-affected harmful factors
If the sauna requires planar soil for installation, then it ensures proper drainage, but it limits installation locations
Solution Approach 1:
The detachable and adjustable leg arrangements provide the adaptability needed to install the sauna on non-planar surfaces such as slopes, uneven ground, or snow-covered terrain. The legs can be adjusted to create a level platform for the sauna body while maintaining the sloped drainage configuration of the base element, thus preserving drainage control while expanding installation location options
Solution Approach 2:
The base element incorporates an integrated drainage system with sloped surfaces and perimeter drainage openings that actively manage water flow. The floor structure is designed with a longitudinal slope that channels water toward drainage points, utilizing gravitational flow in the longitudinal dimension to maintain effective drainage even when installed on varied terrain
