Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless signals are used to identify interactive objects in crowded environments, then object identification capability is enabled, but signal interference and identification accuracy deteriorate

Engineering Contradiction:

Improveobject identification capabilityVSAvoidsignal identification accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system segments the identification process into multiple stages: initial signal detection, pattern analysis, candidate selection, and verification. By dividing the crowded environment into multiple detection zones with different sensitivity levels, the system can selectively process signals from different regions, reducing overall interference while maintaining identification capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary processing layer that analyzes signal patterns before final object identification. This intermediary layer filters and preprocesses wireless signals, extracting characteristic patterns that distinguish valid object signals from background interference, thereby improving identification accuracy in crowded environments.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If signal strength analysis is used to select best candidate object, then object selection accuracy is improved, but processing complexity increases

Engineering Contradiction:

Improveobject selection accuracyVSAvoidsignal processing complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system implements partial action by analyzing only the most relevant signal characteristics (strength patterns over time) rather than all possible signal parameters. It processes signals from a limited number of candidate objects simultaneously, using threshold-based filtering to reduce the set of objects requiring full analysis, thereby balancing accuracy with processing complexity.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system performs preliminary signal filtering and pattern recognition before full object identification. By pre-processing signals to identify characteristic patterns and pre-selecting candidate objects based on initial signal strength thresholds, the system reduces the computational burden of subsequent detailed analysis while maintaining selection accuracy.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If motion tracking is implemented for interactive objects, then user interaction precision is improved, but system resource consumption increases

Engineering Contradiction:

Improvemotion tracking precisionVSAvoidsystem energy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system implements periodic motion tracking at variable intervals rather than continuous tracking. Tracking intensity is adjusted based on object activity levels and interaction context - high-precision tracking is activated only when objects are in active interaction zones or performing significant motions, while low-precision monitoring operates during idle periods, reducing overall energy consumption while maintaining interaction precision.

Inventive Principle:

Principle #19Periodic action

AI summary

An interactive object control system includes processing circuitry with one or more processors and memory storing instructions, that when executed by the processing circuitry cause the processing circuitry to input, into an interactive model, one or more respective characteristics of respective signals received at communication circuitry from respective interactive objects of multiple of interactive objects in an interactive environment. The instructions, when executed by the processing circuitry, cause the processing circuitry to select a best candidate interactive object from the multiple of interactive objects based on the one or more respective characteristics of the respective signals, track motion of the best candidate interactive object, and provide output instructions to one or more special effect components in the interactive environment to generate special effect outputs based on the motion of the best candidate interactive object.
