Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If sensors are attached to rubber products to sense characteristics, then sensing capability is improved, but the ruggedness and elasticity of the rubber product deteriorate
Solution Approach 1:
The patent replaces mechanical sensor attachments with electromagnetic field-based sensing. The system uses electromagnetic fields to interact with the rubber product's molecular structure, detecting changes in electrical impedance and resonance without physical contact or attachment, thus preserving the product's mechanical properties while enabling sensing capabilities
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary between the sensing system and the rubber product. The electromagnetic fields penetrate the product and interact with its molecular structure, allowing indirect measurement of mechanical and chemical influences without physically attaching sensors that would compromise the product's integrity
2Difficulty of detecting and measuring
If the system uses alternating electric fields to monitor forces in polyisoprene products, then sensing features are enhanced, but energy consumption increases
Solution Approach 1:
The patent employs periodic alternating electric fields at specific frequencies to excite the polyisoprene product. By using periodic rather than continuous fields, the system can detect resonant responses and impedance changes while allowing energy to be recovered during field reversal, reducing net energy consumption compared to continuous monitoring approaches
Solution Approach 2:
The patent optimizes the frequency and amplitude parameters of the alternating electric field to match the natural resonant frequencies of the polyisoprene product. This resonance-based approach maximizes sensing sensitivity at minimal energy input, as the product's own molecular vibrations amplify the detection signal without requiring high field strengths
3Adaptability or versatility
If electronic circuitry is embedded in polyisoprene products to create active sensing items, then functionality is enhanced, but device complexity increases
Solution Approach 1:
The patent designs the electromagnetic sensing system to perform multiple sensing functions simultaneously using the same hardware components. The alternating electric field system can detect mechanical stress, chemical composition, temperature, and structural integrity through different analysis of the same electrical impedance and resonance data, eliminating the need for separate sensor systems for each parameter
