Anti seismic protection device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-seismic protection devices for homes, especially in old buildings, face challenges in providing effective protection during earthquakes due to space constraints and the need to remain empty, as they are often filled with household items, rendering them unusable during seismic events.
Innovation Solution
An anti-seismic protection device designed to resemble a shower cabin, utilizing a carbon fibre base and cap frame with intermediate tubular uprights and peripheral walls, which can be installed in place of or alongside a shower cabin, ensuring it remains empty and accessible while providing structural integrity and protection from debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective capsule is installed in a home to provide anti-seismic protection, then safety during earthquakes is improved, but the footprint space occupied by the capsule increases
Solution Approach 1:
The protective capsule is merged with the shower cabin structure, combining safety function with a necessary household facility. The capsule incorporates shower tray, walls, and roofing elements that form both a protective enclosure and a functional shower space, eliminating the need for separate dedicated capsule space.
Solution Approach 2:
The structure serves dual purposes: it functions as a normal shower cabin for daily use and as an anti-seismic protective capsule during earthquakes. The same walls, roof, and base frame provide both shower containment and seismic protection, maximizing space efficiency.
2Reliability
If a protective capsule is installed in a home to provide anti-seismic protection, then safety during earthquakes is improved, but the capsule must remain empty and accessible which limits storage utility
Solution Approach 1:
The protective capsule is merged with the shower cabin structure, combining safety function with a necessary household facility. The capsule incorporates shower tray, walls, and roofing elements that form both a protective enclosure and a functional shower space, eliminating the need for separate dedicated capsule space.
Solution Approach 2:
The structure serves dual purposes: it functions as a normal shower cabin for daily use and as an anti-seismic protective capsule during earthquakes. The same walls, roof, and base frame provide both shower containment and seismic protection, maximizing space efficiency.
3Reliability
If a reinforced protective capsule is installed to guarantee protection during earthquakes, then safety is improved, but the capsule is often filled with household effects which makes it unusable when needed
Solution Approach 1:
The protective capsule is merged with the shower cabin structure, combining safety function with a necessary household facility. The capsule incorporates shower tray, walls, and roofing elements that form both a protective enclosure and a functional shower space, eliminating the need for separate dedicated capsule space.
Solution Approach 2:
The structure serves dual purposes: it functions as a normal shower cabin for daily use and as an anti-seismic protective capsule during earthquakes. The same walls, roof, and base frame provide both shower containment and seismic protection, maximizing space efficiency.
4Strength
If carbon fibre tubular elements and beams are used to construct the frame, then structural strength and seismic resistance are improved, but manufacturing complexity increases
Solution Approach 1:
The frame is segmented into modular components: base frame portion with tubular elements and beams, intermediate frame portion with uprights and walls, and cap frame portion with roofing elements. This segmentation allows for standardized manufacturing of carbon fibre components and simplified assembly through standardized connection interfaces.
Solution Approach 2:
The invention utilizes carbon fibre composite materials for the tubular elements and beams, providing high strength-to-weight ratio and seismic resistance. The composite material construction allows for modular assembly while maintaining structural integrity under seismic loads.
