Rigid Container Floor With Parallel Blind Waves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional container floors made of wood are costly due to high timber consumption and prone to damage during handling, and the introduction of stiffeners in rigid floors complicates automatic welding and increases maintenance.
Innovation Solution
A rigid container floor with parallel blind waves protruding upward, connected by wave connecting plates, which allows for improved strength, reduced assembly deformation, and enables automatic welding, thereby enhancing production efficiency and preventing goods from sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If stiffeners are provided on the rigid floor to increase strength, then the floor strength is improved, but the structure complexity increases and automatic welding becomes difficult
Solution Approach 1:
The patent applies corrugated (wavy) structure to the rigid floor instead of traditional flat stiffeners. The corrugated plate itself provides structural reinforcement through its curved geometry, eliminating the need for separate stiffener components. This curved structure inherently increases floor strength while maintaining a simple, continuous surface that enables automatic welding.
Solution Approach 2:
The invention merges the functions of the floor plate and stiffeners into a single integrated corrugated structure. The corrugated plate simultaneously serves as the floor surface and provides structural reinforcement, eliminating the need for separate stiffener components and their associated complex assembly requirements.
2Strength
If stiffeners are provided on the rigid floor, then the floor strength is improved, but the manufacturing complexity and maintenance cost increase
Solution Approach 1:
The corrugated structure is formed by simple rolling or pressing operations that create the wavy pattern directly in the plate material. This curved geometry provides structural strength through its shape alone, requiring no additional stiffener components or complex assembly steps, thereby simplifying manufacturing while maintaining floor strength.
3Extent of automation
If the rigid floor is designed without stiffeners, then automatic welding is enabled, but the floor strength may be insufficient
Solution Approach 1:
The corrugated structure provides inherent structural strength through its curved geometry, allowing the floor to achieve adequate strength without additional stiffeners. This enables continuous automatic welding of the floor edges to the container shell while maintaining sufficient load-bearing capacity.

AI summary
A rigid container floor and a container with the same floor are disclosed. A plurality of blind waves (1) are provided in parallel on the rigid container floor (10), and upwards protrude out of the upper surface of the rigid container floor (10). The blind wave (1) includes a first edge and a second edge, with the length of the first edge longer than the length of the second edge. The parts between the first edges of the adjacent blind waves and the parts between the first edges of the blind waves and the first edges of the rigid container floor (10) are flat plate structures. The flat plate structures are connected to the blind waves (1) through waved connecting plates, and the parts between the second edges of the blind waves (1) and the second edges of the rigid container floor (10) are connected to the blind waves (1) through waved connecting plates. The multiple blind waves (1) provided in parallel can increase the strength and reduce the assembly deformation. And the edge structure of the rigid container floor (10) can be automatically and continuously welded with a container underframe because the edge parts of the rigid container floor (10) are connected to the blind waves through the waved connecting plates.
