Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operation data includes all detection results from multiple sensors at full frequency, then measurement precision and controllability are improved, but data transmission volume increases and communication efficiency deteriorates
Solution Approach 1:
The patent applies partial action by selectively processing sensor data at different frequencies based on their importance. High-frequency processing is applied to gyrosensor data which requires rapid response, while lower-frequency processing is applied to acceleration sensor data. This selective approach maintains necessary detection precision for critical sensors while reducing overall data transmission volume.
Solution Approach 2:
The patent changes the frequency parameter of data processing and transmission based on sensor type and operational context. The gyrosensor operates at high frequency (9 iterations) for precise angular velocity detection, while the acceleration sensor operates at lower frequency (1 iteration) since it only needs to detect gravitational acceleration changes. This parameter differentiation resolves the contradiction between precision and data volume.
2Ease of operation
If operation data includes data from all sensors at high frequency, then controllability is improved, but processing load increases
Solution Approach 1:
The patent changes processing frequency parameters for different sensors based on their functional requirements. The gyrosensor processes angular velocity at high frequency (9 iterations) to ensure responsive control, while the acceleration sensor processes gravitational data at low frequency (1 iteration) reducing computational load. This differential parameter approach maintains controllability while managing device complexity.
Solution Approach 2:
The patent applies partial action by providing high-frequency processing only where necessary for control precision (gyrosensor for angular velocity) and lower-frequency processing where sufficient (acceleration sensor for gravity detection). This selective processing strategy ensures adequate controllability without unnecessarily increasing overall system complexity and processing load.
3Speed
If transmission cycle is shortened to improve responsiveness, then controllability is improved, but communication efficiency deteriorates due to increased transmission frequency
Solution Approach 1:
The patent changes transmission frequency parameters based on sensor data characteristics. High-speed transmission is applied to gyrosensor angular velocity data (9 iterations) requiring rapid response, while lower-frequency transmission is applied to acceleration sensor data (1 iteration). This parameter differentiation improves responsiveness for critical control data while maintaining communication efficiency by avoiding unnecessary high-frequency transmissions of less time-critical data.
Solution Approach 2:
The patent applies partial high-frequency transmission only to sensors requiring rapid response (gyrosensor) while using lower-frequency transmission for other sensors (acceleration sensor). This selective transmission strategy improves system responsiveness where needed while maintaining overall communication efficiency by reducing total transmission volume.

AI summary
An object is to appropriately transmit operation data from a controller device to an information processing device. The controller device is capable of wirelessly communicating with the information processing device. The controller device includes an operation unit, a generating unit, and a communication unit. The operation unit includes at least a gyrosensor, an acceleration sensor, a direction input unit, and a touch panel. The generating unit generates operation data based on data obtained from the operation unit. The communication unit wirelessly transmits the operation data to the information processing device for each iteration of a predetermined cycle. The operation data transmitted in a single transmission includes: data representing a value obtained by adding together nine pieces of angular velocity detected by the gyrosensor; data representing one piece of acceleration detected by the acceleration sensor; data representing one piece of direction detected by the direction input unit; and data representing ten pieces of position detected by the touch panel.
