Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pressure sensor and circuitry are integrated into the suspension component, then measurement precision of suspension characteristics is improved, but device complexity increases
Solution Approach 1:
The patent combines the pressure sensor, circuitry, and suspension component into a single integrated unit. The circuitry is positioned within the interior space of the suspension component, eliminating the need for separate external measurement devices and reducing overall system complexity while maintaining measurement precision.
Solution Approach 2:
The circuitry and pressure sensor are nested within the interior space of the suspension component tubes. This nested arrangement allows the measurement system to be housed within the existing suspension structure, avoiding additional external components and reducing device complexity.
2Volume of moving object
If the circuitry is disposed within the interior space of the suspension component, then the measurement system becomes more compact, but the space available for other suspension components is reduced
Solution Approach 1:
The patent positions the circuitry in specific locations within the interior space of the suspension component tubes, optimizing the arrangement to minimize interference with other suspension components while maintaining measurement functionality. This localized placement allows for efficient space utilization.
