Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional body bags are used, then they can be manufactured simply, but fluid leakage occurs and contamination results
Solution Approach 1:
The body bag uses a composite structure combining an outer body bag layer and an inner absorbent liner layer. The absorbent liner is made from superabsorbent polymer material that can absorb large amounts of body fluids, while the outer layer provides structural integrity and sealability. This composite approach prevents fluid leakage through the bag walls while maintaining manufacturability through standardized layer construction.
Solution Approach 2:
The absorbent liner acts as an intermediary layer between the remains and the outer body bag. It intercepts and absorbs fluids before they can penetrate through the bag material, preventing contamination of the external environment and personnel. The liner mediates the interaction between bodily fluids and the bag structure, converting a leakage problem into a controlled absorption process.
2Object-affected harmful factors
If remains are sealed within a bag, then concealment is achieved, but bacterial decay is accelerated
Solution Approach 1:
The patent converts the harmful effect of fluid leakage into a beneficial absorption process. The superabsorbent polymer liner actively absorbs and retains body fluids, transforming what would be a contamination hazard into a controlled fluid management system. This prevents fluids from escaping while the absorbent material maintains a barrier against bacterial ingress.
Solution Approach 2:
The absorbent liner functions as a flexible barrier layer that conforms to the remains while maintaining seal integrity. This thin film structure prevents fluid penetration through the bag walls without creating rigid structures that would accelerate decomposition. The flexible membrane approach allows concealment while inhibiting bacterial decay through physical separation.
3Strength
If body bags are made stronger to facilitate lifting and moving, then carrying capability improves, but material weakness from fluid leakage remains
Solution Approach 1:
The body bag is segmented into distinct functional layers: an outer structural layer providing lifting and carrying strength, and an inner absorbent liner handling fluid containment. This segmentation allows each layer to be optimized for its specific function without compromising the other. The outer layer can be made stronger for lifting while the inner liner addresses fluid reliability issues.
Solution Approach 2:
The composite construction combines materials with complementary properties - the outer layer uses strong, flexible material for mechanical strength and lifting capability, while the inner liner uses superabsorbent polymer for fluid containment. This material combination resolves the contradiction by assigning different material requirements to different layers, allowing the bag to be both strong for lifting and reliable for fluid containment.

AI summary
A body bag (900) can be assembled by a stitching process while providing increased fluid retention capabilities. An upper outer layer (101) and a lower outer layer (102), each of which can be non-woven materials, form the outer surfaces of the body bag (900). An absorbent layer (103) is disposed between the upper outer layer (101) and the lower outer layer (102). One or more edges (303,403,503,603) can be folded into a periphery (332) of the body bag (900). Stitching (802) can then be applied along the periphery (332) such that the stitching (802) passes through the upper outer layer (101), the lower outer layer (102), an upper edge (994) of the fold in the absorbent layer (103), and a complementary bottom edge (995) of the fold in the absorbent layer (103). Handles (1001,1002,1003,1004) can be included as well.
