Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional water filtering devices use separate outer bag and filter bag that require assembly, then filtration function is achieved, but portability and ease of use deteriorate due to complex assembly procedures
Solution Approach 1:
The patent combines the outer bag and filter bag into a single integrated water filtering device. The filter units are directly attached to the filter bag, eliminating the need for separate assembly of outer and inner bags. This merging of components resolves the technical contradiction by maintaining filtration functionality while significantly improving ease of use and reducing assembly complexity.
2Reliability
If conventional water filtering devices use single-layer filter bag, then basic filtration is achieved, but filtration effectiveness deteriorates due to inability to filter both impurities and bacteria
Solution Approach 1:
The patent divides the filtration function into multiple segments with different filter units (first filter unit, second filter unit, third filter unit) positioned at different locations within the filter bag. Each filter unit targets different types of contaminants, enabling comprehensive filtration of both impurities and bacteria. This segmentation approach resolves the contradiction by enhancing filtration effectiveness while maintaining a manageable device structure.
Solution Approach 2:
Different regions of the filter bag are equipped with different filter units having specialized filtration properties. The first filter unit addresses impurities, the second filter unit targets bacteria, and the third filter unit provides additional filtration. This local differentiation of filtration quality across different parts of the device resolves the technical contradiction by achieving comprehensive filtration effectiveness without excessive overall complexity.
3Reliability
If conventional water filtering devices lack dedicated storage space, then device simplicity is maintained, but filtered water security deteriorates due to contamination risk
Solution Approach 1:
The patent implements a nested structure where the filter bag containing filtered water is placed inside the outer bag. This nested arrangement creates dedicated storage space for filtered water while using the outer bag as a protective container. The nesting principle resolves the technical contradiction by ensuring filtered water security through physical separation and protection, while adding only minimal structural complexity compared to a completely separate storage system.

AI summary
A water filtering device includes a filter bag and an outer bag. The filter bag is internally provided with a first and a second filter unit. The first filter unit is connected at upper ends to a top opening of the filter bag to form a lower folded section and define a first water filtering space in the filter bag. The second filter unit is fixedly connected to a water outlet on a bottom of the filter bag and defines a second water filtering space in the filter bag. A filter material is provided in the second water filtering space. The outer bag covers the filter bag, such that a water storing space is formed between the outer bag and the filter bag. The water filtering device is conveniently portable and saves any assembling procedure, and can effectively filter water and store the filtered water.
