Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive tape is used to collect particles from the magnetic bar, then particles can be collected, but particles remain stuck to the adhesive and are difficult to remove, resulting in loss of information and potential surface contamination
Solution Approach 1:
The invention extracts the harmful adhesive substance from the collection process entirely. Instead of using adhesive tape that leaves particles stuck, the patent uses a magnetic field to directly attract and hold particles on a non-adhesive surface, allowing complete particle recovery without contamination or loss.
Solution Approach 2:
The invention introduces a magnetic field as an intermediary mechanism between the magnetic bar and the collection surface. This magnetic field mediator allows particles to be transferred and held without direct adhesive contact, enabling complete particle recovery while preventing surface contamination.
2Ease of operation
If a cloth is used to collect particles from the magnetic bar, then particles can be collected, but cleaning the cloth requires immersion in solvent and filtering, and not all particles are recovered, leaving residue on the magnetic strip
Solution Approach 1:
The invention removes the cloth intermediate step entirely from the collection process. By using a magnetic field to directly hold particles on a collection surface, the system eliminates the need for cloth cleaning operations and achieves complete particle recovery without residue left on the magnetic strip.
Solution Approach 2:
The invention replaces the mechanical cloth-based collection system with a magnetic field-based system. This substitution eliminates the need for mechanical cleaning operations and solvent immersion, achieving complete particle recovery through magnetic attraction alone.
3Ease of operation
If a more powerful magnet is used to directly collect particles from the bar, then particles can be collected, but the magnetic stopper may be altered by modifying its remanent field
Solution Approach 1:
The invention extracts the powerful magnet from direct contact with the magnetic stopper. Instead of using a stronger magnet that could alter the stopper's magnetic field, the patent uses a magnetic field as an intermediary that achieves particle collection without modifying the original magnetic plug's remanent field, preserving its integrity.
4Ease of operation
If traditional collection methods are used, then particles can be collected, but the process is time-consuming and may leave residue that skews subsequent pollution readings
Solution Approach 1:
The invention enables continuous and complete particle collection through magnetic attraction without interruption for cleaning or multiple steps. The magnetic field continuously holds all particles on the collection surface, eliminating time-consuming intermediate operations and ensuring complete recovery that prevents skewed readings in subsequent analysis.
