Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If configuration data is sent over a single wireless channel, then lighting effects can be transmitted, but reporting data may be lost or corrupted due to bandwidth consumption and interference

Engineering Contradiction:

Improvelighting effect dataVSAvoidreporting data

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The wireless communication channel is segmented into dedicated time slots: configuration data transmission occurs in one time slot while reporting data transmission occurs in another time slot. This temporal segmentation prevents interference between the two data types and ensures reliable reporting data transmission while still allowing lighting effect configuration to be sent.

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If compression schemes are applied to lighting effect data, then bandwidth usage is minimized, but data transfer efficiency must be optimized to maintain effect quality

Engineering Contradiction:

Improvebandwidth usageVSAvoiddata transfer efficiency

Core Design Contradiction:

Quantity of substanceVSProductivity

Solution Approach 1:

The patent applies compression schemes that transform lighting effect data into a more compact representation by identifying and encoding only the changed parameters (delta changes) between frames. This reduces the quantity of data transmitted while maintaining the ability to reconstruct the original lighting effects, thereby minimizing bandwidth usage without sacrificing effect quality.

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If a single wireless channel is used for two-way communication, then device complexity is reduced, but interference from other devices increases the risk of data loss

Engineering Contradiction:

Improvecommunication channelVSAvoiddata transmission

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The communication system uses periodic time-division multiplexing where configuration data and reporting data are transmitted in alternating periodic time slots. This periodic structure organizes the single wireless channel usage, reducing interference and collision risks while maintaining simple device architecture. Other wireless devices cause less interference because the structured time slots reduce random access conflicts.

Inventive Principle:
