Foldable RCS Container With Angled Cladding Boards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard containers used in the defense sector have a large radar cross section due to their vertical metallic side walls, making them easily detectable and vulnerable, and existing camouflage methods like paint provide limited improvement.
Innovation Solution
The container features foldable side walls with integrated cladding boards that contain reflective agents aligned at angles to reflect radar radiation at oblique angles, reducing the effective radar cross section, and includes a double-leaf door and post elements connected by threaded spindles for easy handling and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standard containers are equipped with vertical metallic side walls for structural strength and standardization, then manufacturing ease and structural strength are improved, but radar cross section increases making them easily detectable
Solution Approach 1:
The side walls are divided into multiple cladding boards with different orientations. Each cladding board is segmented at specific angles (e.g., 45 degrees) relative to the vertical axis, creating multiple surfaces that reflect radar waves in different directions rather than returning them directly to the source.
Solution Approach 2:
The cladding boards are arranged asymmetrically with respect to the vertical axis, with angles deviating from the standard vertical orientation. This asymmetric arrangement ensures that radar waves are reflected at oblique angles away from the container, reducing the effective radar cross section while maintaining structural integrity.
2Volume of moving object
If containers are made foldable to save storage space, then storage efficiency is improved, but device complexity and maintenance requirements increase
Solution Approach 1:
The container incorporates movable connection elements that allow the cladding boards to be folded and unfolded. The connection elements enable dynamic transformation between the folded state (for compact storage) and the unfolded state (for operational use), with the cladding boards being foldable relative to the container walls along predefined axes.
3Object-affected harmful factors
If camouflage paint is applied to reduce visibility and radar signature, then detection resistance is improved, but the improvement is limited and maintenance becomes complex
Solution Approach 1:
Instead of using camouflage paint, the invention employs geometric shaping through angled cladding boards that physically redirect radar waves. The angular geometry of the cladding boards creates a passive optical/electromagnetic effect that reduces radar signature without requiring maintenance-intensive paint applications.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly reduces the container's radar detectability and visibility, enhancing its stealth capabilities while maintaining ease of use and handling, even when folded.
Implementation Method 1
The cladding board (110) has a reflective agent (140) embedded therein which is aligned so as to be at least partially inclined in relation to a plane of main extent (160) of the cladding board (110). The reflective agent (140) is configured to reflect radar rays (150) in an outgoing direction that deviates from an antiparallel direction of incidence.

AI summary
A container may have a floor, a ceiling, a first side wall, and a second side wall, a first end wall, and a second end wall. The first side wall, the second side wall, the first end wall, and the second end wall may be formed from a container wall for reducing an effective radar cross section of the container. The first side wall and the second side wall in a longitudinal direction of the container mid-height between the floor and the ceiling may be foldable inward into the interior of the container. The first side wall may include a first cladding board that is permeable to radar rays and reduces the effective radar cross section of the container. The first cladding board may have a reflective agent that reflects radar rays and can be aligned to be at least partially inclined relative to a plane of a main extent of the first cladding board.
