Solution Overview
Problem
Conventional solar collectors for thermal energy generation on roofs and facades are complex to assemble and require specialized knowledge due to their large dimensions and weight, making them cumbersome to transport and install, especially for non-experts.
Innovation Solution
A solar collector kit comprising a foldable cover, a hose-like flexible housing, and an absorber, with insulating foam used to shape and stabilize the housing upon assembly, allowing for easy transportation and assembly by non-specialists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional solar collectors are designed as complete pre-assembled panels, then structural stability and thermal insulation are ensured, but transport and assembly become cumbersome due to large dimensions and high weight
Solution Approach 1:
The solar collector is divided into separate modular components: a flexible housing, a cover, an absorber, and insulating foam in packaging units. These segments can be transported independently and assembled on-site, eliminating the need to handle large pre-assembled panels while maintaining structural integrity through the flexible housing that contains all components in a compact form.
Solution Approach 2:
The cover, absorber, and insulating foam are nested within the flexible housing, which acts as a containing structure. This nesting approach allows all components to be transported in a compact, space-efficient manner while being easily separable for assembly, resolving the contradiction between compact transport and stable construction.
2Stability of the object's composition
If solar collectors are designed as complete pre-assembled panels, then structural integrity is maintained, but assembly requires specialist knowledge and is time-consuming
Solution Approach 1:
The housing, cover, and absorber are pre-formed as complete components with integrated connection features. The flexible housing is pre-shaped to accommodate the absorber and cover, and connection elements are pre-positioned, allowing assembly to proceed through simple insertion and connection actions without requiring specialized knowledge or time-consuming adjustments.
3Area of stationary object
If large-area individual parts are used, then collector area is increased, but coordination and adaptation of fastening parts become complex
Solution Approach 1:
The flexible housing serves multiple functions simultaneously: it contains the absorber and insulating foam, provides structural support, enables transport in a compact form, and facilitates assembly through its elastic properties. This multi-functionality eliminates the need for separate, complex fastening and coordination parts, allowing the housing itself to adapt to different installation situations while maintaining simplicity.
