Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If large-scale acceleration sensation devices are used, then the clarity of acceleration sensation is improved, but the device complexity and cost increase
Solution Approach 1:
The device segments the acceleration sensation presentation function into two independent components: movable weights for generating acceleration sensation through center of gravity change, and vibration driving units for enhancing the sensation clarity. This segmentation allows each component to be optimized independently, achieving clear acceleration sensation without requiring large-scale complex systems.
Solution Approach 2:
The device employs dynamically movable weights that can change position along the longitudinal axis of the headgear, enabling real-time adjustment of the center of gravity to match varying acceleration patterns. This dynamic adaptation allows the compact device to effectively present clear acceleration sensations for different motion scenarios without requiring a large fixed structure.
2Measurement precision
If movable weights are added to change center of gravity, then acceleration sensation is enhanced, but the weight of the headgear increases
Solution Approach 1:
The device uses relatively small movable weights (totaling a modest portion of the headgear's overall weight) to generate sufficient acceleration sensation. Rather than requiring large masses, the combination of movable weights and vibration enhancement achieves effective acceleration presentation with minimal weight addition, making the headgear wearable and comfortable.
3Measurement precision
If vibration driving units are added, then the clarity of acceleration sensation is improved, but the device complexity increases
Solution Approach 1:
The device merges the functions of acceleration generation (movable weights) and sensation enhancement (vibration driving units) into a single integrated headgear system. This combination allows the vibration units to amplify and clarify the acceleration sensation produced by the weights, achieving high clarity without requiring separate large-scale devices for each function.
