Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If wired programming and upgrading is used for the tire pressure sensor, then the upgrading process can be completed with existing tools, but the operation becomes complex and labor-intensive requiring physical removal and connection to programming tools

Engineering Contradiction:

Improveupgrading process simplicityVSAvoidoperation complexity

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent replaces the mechanical wired connection system with a wireless communication system. The tire pressure sensor uses its existing wireless communication module to receive upgrade files and enter upgrade mode through wireless signals, eliminating the need for physical removal and wired connection to programming tools. This substitution directly resolves the contradiction by maintaining upgrading capability while eliminating operational complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If wired programming and upgrading is used for the tire pressure sensor, then the upgrading can be performed with current technology, but the tire may be damaged during the removal process

Engineering Contradiction:

Improveupgrading safetyVSAvoidtire damage risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent eliminates the mechanical removal and physical handling of the tire pressure sensor by implementing wireless upgrade file reception and wireless trigger signal activation. The sensor remains installed on the tire throughout the upgrading process, receiving upgrade files and control signals wirelessly, thereby completely avoiding the risk of tire damage during removal and installation operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If wired programming and upgrading is used for the tire pressure sensor, then the existing programming tools can be utilized, but much manpower is required and the process efficiency is low

Engineering Contradiction:

Improveupgrading efficiencyVSAvoidmanpower requirement

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent replaces the manual wired programming process with an automated wireless system. The tire pressure sensor autonomously receives upgrade files wirelessly, and the control device wirelessly triggers the upgrade process without requiring physical intervention. This eliminates the need for manual removal, connection, and monitoring operations, dramatically improving upgrading efficiency and reducing manpower requirements.

Inventive Principle:
