Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single detection section is used to detect holding by the user, then the device structure is simple, but the detection reliability deteriorates when sensor sensitivity deteriorates or the user wears gloves
Solution Approach 1:
The patent combines multiple detection sections (first detection section for holding detection and second detection section for operation detection) to work together. This merging of detection functions ensures that even if one detection section fails to detect properly (e.g., when wearing gloves), the other can compensate, thereby improving overall detection reliability without significantly increasing device complexity.
Solution Approach 2:
The detection system is designed with multi-functionality where the first detection section detects holding state and the second detection section detects operation state. This universal detection approach allows the system to adapt to different usage scenarios (with or without gloves) by utilizing different detection sections as needed, improving reliability across various conditions.
2Ease of operation
If the device operates in normal operation mode, then the usability is good, but the power consumption increases
Solution Approach 1:
The patent implements dynamic operation mode switching between power saving mode and normal operation mode based on detection results. The control section dynamically adjusts the operation mode by detecting holding state through the first detection section and operation state through the second detection section, allowing the device to adapt power consumption levels to actual usage conditions, thereby improving usability while managing power consumption efficiently.
Solution Approach 2:
The system changes operational parameters by switching between different operation modes. In power saving mode, power consumption is reduced, while in normal operation mode, full functionality is available. The control section changes these operational parameters based on detection results, enabling the device to optimize the balance between usability and power consumption according to actual usage scenarios.
3Use of energy by moving object
If the device switches to power saving mode, then the power consumption is reduced, but the usability deteriorates when the user needs to use the device
Solution Approach 1:
The patent implements a feedback mechanism where the control section continuously monitors detection results from both detection sections and adjusts operation mode accordingly. When the first detection section detects holding or the second detection section detects operation, the system provides feedback to switch from power saving mode to normal operation mode, ensuring usability is maintained when needed while keeping power consumption low during idle periods.
Solution Approach 2:
The system performs preliminary detection using the first detection section to detect holding state before full operation is required. This preliminary action allows the device to anticipate user needs and switch from power saving mode to normal operation mode in advance, ensuring that when the user actually uses the device, it is already in the appropriate operational state, thereby maintaining usability while minimizing unnecessary power consumption.

AI summary
A pointing object is provided with a first sensor (a first detection section) adapted to detect that the pointing object has been held, a detection circuit section (a second detection section) adapted to detect that a first operation switch has been operated, and a pointing object control section capable of switching an operation mode of the pointing object between a normal operation mode (a first operation mode) in which the pointing object operates in an operation state suitable for a usage, and a power saving mode (a second operation mode) with a power consumption reduced to a level lower than in the normal operation mode, and adapted to switch the operation mode based on a detection result of the first sensor and a detection result of an operation of the first operation switch.
