Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current building structures lack comprehensive disaster prevention measures against water damage, earthquakes, and flooding, as they do not integrate seismic isolation, water resistance, and evacuation solutions, and existing technologies are not designed for sustainable water conservation or fire prevention.
Innovation Solution
A building structure incorporating a drained buoyancy tank at its base for flood resistance, with telescopic and movable columns for seismic isolation, utilizing stored rainwater for domestic purposes, firefighting, and evaporative cooling, and featuring detachable lifeboats for evacuation, which can float during floods and provide buoyancy using Archimedes' principle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional waterproofing technology is used to prevent water infiltration, then water resistance is improved, but seismic resistance and vibration control functions are not provided
Solution Approach 1:
The building structure integrates multiple functions into a unified system: the waterproof basement structure provides both water resistance and seismic isolation through rubber isolators, while water storage tanks serve dual purposes of flood prevention and earthquake fire protection. This multi-functional design resolves the contradiction by making the structure adaptable to both water damage and seismic disasters.
Solution Approach 2:
The patent merges previously separate systems (waterproofing, seismic isolation, fire protection, and evacuation) into an integrated building structure. The basement waterproofing system is combined with seismic isolation mechanisms, and water storage tanks are positioned to serve both flood buoyancy and fire fighting purposes, creating a unified disaster prevention system.
2Reliability
If seismic isolation technology is used to reduce earthquake shaking, then seismic resistance is improved, but contribution to water damage prevention is virtually none
Solution Approach 1:
The seismic isolation system is integrated with the waterproof basement structure, creating a unified foundation system that provides both seismic protection and water resistance. The rubber isolators are installed within the waterproof basement, allowing the same structural element to serve dual disaster prevention functions.
Solution Approach 2:
The patent combines seismic isolation technology with waterproofing systems by installing rubber isolators within the waterproof basement structure. This merging allows the foundation system to simultaneously address both seismic and water damage risks.
3Reliability
If water storage tanks are installed for fire protection, then firefighting capability is improved, but device complexity increases
Solution Approach 1:
The water storage tanks are positioned in the basement to serve multiple functions: they provide fire protection water, contribute to buoyancy during flooding, and lower the building's center of gravity for seismic stability. This multi-functional use of the same water storage system resolves the contradiction by avoiding additional dedicated structures.
Solution Approach 2:
The patent merges fire protection water storage with flood prevention buoyancy systems by positioning water tanks in the basement. The same water bodies serve both fire fighting and flood buoyancy purposes, reducing the need for separate systems.
4Reliability
If specialized floating structure is designed for water damage, then water resistance is improved, but convenience and practicality in normal times deteriorates
Solution Approach 1:
The building structure incorporates movable support columns that can extend or retract based on water levels. During normal times, the columns are retracted and the building functions as a conventional structure. During flooding, the columns extend to elevate the building, providing adaptability without compromising normal usability.
Solution Approach 2:
The support column length parameter is changed dynamically based on water levels. The columns can extend from a retracted state during normal operation to an extended state during flooding, allowing the structure to adapt its height parameter in response to changing environmental conditions.
