Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If onboard light emitters and power-consuming sensors are used for positional and orientation tracking, then tracking functionality is achieved, but energy consumption increases and operational efficiency decreases
Solution Approach 1:
The patent extracts the tracking sensors and light emitters from the portable device, relocating them to the environment infrastructure. This allows the device to determine position and orientation through external transceivers and antennas without consuming energy for onboard sensing, directly resolving the contradiction between tracking capability and energy consumption.
Solution Approach 2:
The patent introduces external transceivers and ultra-wideband communication as an intermediary mechanism between the portable device and the environment. This mediator enables positional and orientation determination through signal processing by external systems rather than through power-consuming onboard sensors.
2Adaptability or versatility
If multiple targets and interactive elements are deployed in the environment, then interactive capabilities are enhanced, but maintenance requirements and operational complexity increase
Solution Approach 1:
The patent creates a universal tracking infrastructure where external transceivers and antennas serve multiple functions: tracking portable devices, determining device orientation, and enabling interactions with multiple targets. This multi-functional system enhances interactive capabilities while reducing operational complexity compared to individual tracking systems for each element.
Solution Approach 2:
The environment infrastructure automatically performs tracking and interaction detection through the external transceiver system, eliminating the need for manual maintenance of individual targets and reducing operational complexity. The system self-manages the coordination between multiple interactive elements and portable devices.
3Duration of action of moving object
If rechargeable battery and charging system are implemented, then device longevity is improved, but system complexity and charging infrastructure requirements increase
Solution Approach 1:
The patent merges the charging function with the existing environmental infrastructure by integrating charging stations into the attraction system. This combination allows portable devices to be recharged during use without requiring separate charging infrastructure, improving device longevity while minimizing additional system complexity.
Solution Approach 2:
The charging station acts as an intermediary between the power source and the portable device battery. It provides protected charging through electrical couplers and protective layers, enabling extended device operation while managing the complexity of power delivery through a standardized interface.
4Reliability
If protective electrical layers are added to charging system, then device protection from abnormal voltage and current is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent implements protective electrical layers and circuitry in advance within the charging station to prevent damage from abnormal voltage and current. This beforehand protection mechanism safeguards the portable device during charging while the complexity is contained within the charging infrastructure rather than the portable device itself.
Solution Approach 2:
The patent extracts the protective charging infrastructure from the portable device and places it in the charging station. This allows complex protection mechanisms to be implemented in the stationary charging system where they can provide device protection without adding complexity to the portable device manufacturing.

AI summary
A portable device aim identification system includes a display screen, a transceiver, a portable device, and an interactive device system. The portable device includes multiple antennas. The transceiver, which is separate from the portable device, is configured coordinate with the multiple antennas of the portable device to generate data based on signals communicated between the transceiver and the multiple antennas. The interactive device system functions to track position and/or orientation of the portable device based on the data, identify an aim location of the portable device based on the position and/or orientation of the portable device, and control the display screen to present a graphic at the aim location in response to the aim location being on the display screen.
