Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a device operates in discoverable state to allow multiple connection requests, then device discoverability is improved, but connection security and power consumption deteriorate

Engineering Contradiction:
Improvedevice discoverabilityVSAvoidconnection security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the discoverable state into two distinct operational modes: a first discoverable state where the device accepts connection requests from any device, and a second discoverable state where the device only accepts requests from specific devices identified in a whitelist. This segmentation allows the system to balance between broad discoverability and secure, selective connectivity by transitioning between states based on connection requirements

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a device processes all connection requests in discoverable state, then connection opportunities are increased, but power consumption increases

Engineering Contradiction:
Improveconnection opportunitiesVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic state transitions between two discoverable states based on real-time connection requirements. The device can switch from a high-power first discoverable state (accepting all requests) to a low-power second discoverable state (accepting only whitelisted requests), thereby optimizing power consumption while maintaining necessary connection opportunities

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Instead of continuously maintaining the full first discoverable state, the patent applies partial action by using the second discoverable state with restricted acceptance criteria. This partial operation mode consumes less power while still providing connection opportunities for authorized devices, eliminating the need for excessive power consumption

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If device selection criteria are made strict to improve connection quality, then connection reliability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveconnection reliabilityVSAvoidease of device selection
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements automatic whitelist management where the device autonomously identifies and adds frequently connected devices to the whitelist without requiring manual user configuration. This self-service mechanism maintains strict security criteria while simplifying operation, as the system automatically adapts to user preferences over time

Inventive Principle:
Principle #25Self-service
