Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power storage devices, such as batteries and accumulators, occupy significant space and do not meet the optical and haptic requirements for decorative surfaces, making them unsuitable for integration into interior design, especially in urban areas where space is limited.
Innovation Solution
A multi-layer composite structure with a polymeric intermediate layer containing a first conductor, anode, separator, and cathode, where the separator is ion-permeable and can be replaced by a solid electrolyte, allowing for compact energy storage and release while maintaining a visually appealing surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional power storage devices are installed, then energy storage capacity is improved, but installation space requirement increases
Solution Approach 1:
The patent combines the power storage device with the cladding element into a single integrated structure. The battery components (electrodes, separator, electrolyte) are embedded within the cladding layers, allowing the wall or ceiling to serve dual functions as both decorative covering and energy storage medium, thereby eliminating the need for separate storage spaces
Solution Approach 2:
The cladding element is designed to perform multiple functions simultaneously: it provides decorative surface covering while also serving as an energy storage device. This multi-functionality allows the same structure to fulfill both aesthetic and energy storage requirements, reducing overall space consumption
2Quantity of substance
If conventional power storage devices are installed, then energy storage capacity is improved, but visual appearance deteriorates
Solution Approach 1:
By merging the battery structure with the cladding element, the power storage components become integrated within the decorative layers. The top layer with its grain structure and the bottom layer with textile carrier completely enclose and conceal the battery components, making the energy storage function invisible while maintaining aesthetic appearance
Solution Approach 2:
The polymeric intermediate layer acts as an intermediary that houses the battery components while being sandwiched between the decorative top layer and the textile bottom layer. This intermediate structure allows the battery to be concealed within the cladding assembly, preserving the visual appearance of the surface
3Volume of stationary object
If compact energy storage device is used, then installation space is reduced, but protection against short circuits deteriorates
Solution Approach 1:
The separator serves as an intermediary layer between the positive and negative electrodes, providing physical separation and preventing direct contact that would cause short circuits. The separator is impregnated with electrolyte and positioned within the polymeric intermediate layer, ensuring electrical isolation while maintaining ionic conductivity for normal battery operation
Solution Approach 2:
The separator is extracted as a distinct functional layer within the battery structure, specifically positioned between the electrodes to provide dedicated short circuit protection. This separate protective layer ensures that even in the compact integrated design, adequate protection against electrode contact is maintained
