Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single dissolved oxygen shimmer probe is used for detection, then the device complexity is low, but the detection range is small and only one position can be detected at a time
Solution Approach 1:
The detection system is divided into multiple independent detection probes, each capable of detecting dissolved oxygen at different positions. The probes are arranged in an array within the casing, allowing simultaneous detection across multiple locations in the sludge-water interface, thereby expanding the detection range without requiring a single complex probe
Solution Approach 2:
Multiple detection probes are integrated into a single casing structure that can be deployed together as one unit. The casing holds multiple probes at predetermined positions and depths, combining their functions into a unified detection system that operates simultaneously across the sludge-water interface
2Measurement precision
If sample extraction is performed for detection, then the detection can be conducted in a controlled environment, but the natural environment around the sludge-water interface changes leading to inconsistent data
Solution Approach 1:
A transparent casing is introduced as an intermediary structure that allows optical detection without direct contact with the sludge sample. The casing acts as a mediator that permits light transmission for fluorescence detection while maintaining the natural sludge-water interface environment, eliminating the need for sample extraction and preserving data consistency
Solution Approach 2:
The mechanical sample extraction process is replaced by an optical detection system. Instead of physically removing and transporting samples, the invention uses light-based fluorescence detection through the transparent casing, eliminating mechanical disturbance to the sludge-water interface and ensuring reliable, consistent measurements
3Ease of operation
If mechanical operation is used to control probe height, then the probe position can be adjusted, but the mechanical parts are easily damaged causing time-consuming operation
Solution Approach 1:
Mechanical adjustment mechanisms for probe positioning are replaced with a flexible probe design that can be manually bent to desired angles and positions. The probes are made flexible rather than rigid, allowing easy positioning without complex mechanical joints or actuators, thereby improving both ease of operation and reliability by eliminating fragile mechanical parts
Solution Approach 2:
The probes are designed with flexible properties rather than fixed rigid structures, allowing them to be dynamically positioned by hand bending to various angles and depths. This dynamic flexibility replaces static mechanical positioning systems, making the device easier to operate and more reliable by eliminating mechanical failure points
4Productivity
If multiple detection probes are used to detect different positions, then the detection range expands, but the device complexity increases
Solution Approach 1:
The detection function is segmented into multiple independent probes, each handling detection at a specific position. This segmentation allows parallel detection across multiple locations simultaneously, dramatically improving productivity while keeping each individual probe simple in design
Solution Approach 2:
All detection probes within the casing are designed with the same universal structure and function, detecting dissolved oxygen at their respective positions using identical fluorescence-based sensing mechanisms. This universality simplifies the overall device design by repeating a standardized module rather than creating complex unique structures for each probe

Function Achieved in This Case
Enables broad, quick, and convenient detection of dissolved oxygen across various positions and heights, protecting probes from damage and maintaining environmental integrity, thus providing accurate and efficient data collection.
Implementation Method 1
an optical fiber information exchange sensor based on a fluorescence quenching principle; since oxygen is a natural quencher for some fluorescent indicators, oxygen-sensitive fluorescent indicators are made into oxygen sensing membranes coupled to the end part of the optical fiber
