Telescopic Pontoon Bridge Supports for Flood Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pontoon bridges face challenges in supporting high loads due to heavy and costly supports, which are inflexible and difficult to transport, and are prone to flooding or unable to accommodate varying water levels.
Innovation Solution
A float system where the buoyancy body and supports are slidably mounted, allowing the buoyancy body to adjust its immersion depth with a spring element and bearing unit, distributing load more efficiently and reducing the weight and cost of supports, while maintaining a stable road surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the supports are made very stable to absorb high loads, then the load-bearing capacity is improved, but the weight and manufacturing cost increase significantly
Solution Approach 1:
The support is designed as an extendable telescopic structure with multiple segments that can be extended or retracted. When the buoyancy body is pressed deeper into the water by high loads, the support automatically extends to maintain stability. This dynamic adjustment allows the support to provide high stability only when needed, rather than being permanently over-engineered for maximum load conditions.
Solution Approach 2:
The length of the support is variable rather than fixed. The support can change its effective length based on the immersion depth of the buoyancy body and the water level. This parameter change allows the same support structure to adapt to different load conditions and water levels, reducing the need for excessively heavy and long supports designed for worst-case scenarios.
2Strength
If the supports are made very stable to absorb high loads, then the load-bearing capacity is improved, but the transportability deteriorates
Solution Approach 1:
The telescopic support structure can be collapsed to a compact size for transport and then extended when deployed. This dynamic transformation allows the support to have high load-bearing capacity when in use (extended state) while being easy to transport when collapsed. The support effectively transforms between two functional states: a compact transport state and an extended operational state.
3Object-generated harmful factors
If the buoyancy body protrudes completely from the water to avoid flow resistance, then the flow resistance is reduced, but the buoyancy force available to support loads decreases
Solution Approach 1:
The system dynamically adjusts the immersion depth of the buoyancy body based on the load requirements. When loads are light, the buoyancy body protrudes more to reduce flow resistance. When heavy loads need to be supported, the buoyancy body is pressed deeper into the water, and the extendable support compensates by extending its length. This dynamic adjustment allows the system to optimize both flow resistance and buoyancy force utilization depending on operating conditions.
4Object-affected harmful factors
If the support length is fixed to prevent flooding when water level rises, then the flood protection is improved, but the adaptability to varying water levels and load conditions deteriorates
Solution Approach 1:
The support length is made variable through the telescopic mechanism, allowing it to adapt to different water levels. When water levels rise, the support can be extended to maintain the road surface elevation and prevent flooding. When water levels fall or loads decrease, the support can be retracted. This dynamic length adjustment provides both flood protection and adaptability to varying conditions.
Solution Approach 2:
The key parameter of support length is made changeable rather than fixed. The telescopic mechanism allows continuous or discrete adjustment of the support length to match varying water levels and load conditions. This parameter change enables the system to respond dynamically to environmental changes while maintaining structural integrity and flood protection.

Function Achieved in This Case
Enables the pontoon bridge to absorb higher loads with lighter, more cost-effective supports and adapt to changing water levels, reducing the risk of flooding and improving transportability.
Implementation Method 1
the load acting on the ponton bridge is almost completely supported by the supports... a part of the load acting on the bridge is received from the buoyancy force of the buoyancy body
Implementation Method 2
the buoyancy body relative to the support is vertically displaceable... a bearing unit with a bearing unit is provided between buoyancy body and the support
