Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction methods for precast concrete bridges are hindered by the weight and fragility of components during transport, and conventional in-situ construction is time-consuming and expensive, requiring high expert supervision.
Innovation Solution
A modular system comprising formwork members and reinforcement members that create a cavity for concrete, allowing for the formation of elongate beams, enabling efficient assembly and integration of modules to form bridges or building structures with improved structural integrity and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If precast concrete components are used for bridge construction, then structural integrity is improved, but weight increases and components become difficult to transport and easily damaged
Solution Approach 1:
The bridge is divided into multiple modular segments that can be manufactured separately and assembled on-site. Each module contains formwork members, reinforcement members, and concrete, creating self-contained units that are lighter than traditional precast components while maintaining structural integrity through the modular design and interconnection mechanisms.
2Adaptability or versatility
If conventional in-situ construction methods are used, then flexibility in construction is maintained, but construction time increases and expert supervision requirements increase
Solution Approach 1:
The formwork members and reinforcement members are pre-assembled into modular units with integrated cavities before concrete pouring. This preliminary assembly of structural components into standardized modules reduces on-site construction time and simplifies the assembly process while maintaining adaptability through modular configuration.
3Strength
If precast concrete components are used, then structural strength is improved, but ease of transport deteriorates due to weight and fragility
Solution Approach 1:
The bridge structure is segmented into multiple lightweight modules that can be transported individually. Each module contains integrated formwork, reinforcement, and concrete in a compact configuration, reducing transport difficulties compared to traditional heavy precast components while maintaining structural strength through the modular assembly.
4Adaptability or versatility
If conventional construction methods are used, then structural customization is possible, but construction cost increases due to expert supervision requirements
Solution Approach 1:
The modular system uses standardized formwork members and reinforcement members that can be configured for different bridge designs and structural requirements. The universal modules maintain customization capability through flexible arrangement and configuration while reducing construction costs by eliminating the need for expensive expert supervision during assembly.

AI summary
A construction module for a structure, comprising: a formwork member that includes a base, a pair of parallel side walls that extend upwardly from the base, and a pair of parallel end walls. The base, the side walls and the end walls define a cavity for reinforcement and concrete. A reinforcement member includes an upper portion and a lower portion. When the reinforcement member is located in the cavity and concrete fills the cavity, the lower portion of the reinforcement member and the concrete define an elongate beam.
