Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual connection setup is required between devices for data search, then connection reliability is improved, but operation complexity and time consumption increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoidsearch operation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by automatically establishing connections between devices before the user initiates a search operation. The first device proactively discovers and connects to second and third devices, so that when the user enters a search keyword, the connection infrastructure is already in place and search results can be immediately retrieved and displayed from all connected devices.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements self-service by enabling the first device to automatically manage connections with other devices without requiring user intervention. The device autonomously discovers available devices, establishes connections, and maintains connection status, freeing the user from manual connection setup tasks while ensuring reliable connections for data search operations.

Inventive Principle:
Principle #25Self-service

2Stability of the object's composition

If manual connection setup is required between devices, then connection stability is improved, but search efficiency and productivity decrease

Engineering Contradiction:
Improveconnection stabilityVSAvoidsearch efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The system performs preliminary connection establishment between the first device and other devices before the search operation begins. By pre-discovering and pre-connecting to available devices, the system ensures that when a search is initiated, all connection pathways are already established and stable, enabling immediate parallel data retrieval from multiple devices without sequential connection setup delays.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system merges multiple connection operations into a single automated process. Instead of requiring separate manual connections to each device, the first device simultaneously discovers and connects to multiple devices (second device, third device, etc.) in one unified operation, thereby maintaining connection stability while dramatically improving search efficiency by enabling parallel data retrieval from all connected devices.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If simultaneous search across multiple devices is enabled without prior connection, then user experience and ease of operation are improved, but system complexity increases

Engineering Contradiction:
Improvesearch operation simplicityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system introduces an intermediary automated connection management mechanism that mediates between the simple user search operation and the complex multi-device search execution. When the user enters a search keyword, the intermediary layer automatically handles device discovery, connection establishment, coordinate the search across multiple devices, and aggregate results, shielding the user from system complexity while enabling simultaneous multi-device search.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements self-service through automated connection management that handles the complexity of multi-device coordination internally. The first device autonomously discovers available devices, establishes connections, manages connection states, and coordinates the search operation across all connected devices without user intervention. This self-service approach maintains simple user interaction while the system internally manages the necessary complexity for simultaneous multi-device searching.

Inventive Principle:
Principle #25Self-service
