Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a modular stacked arrangement with interchangeable modules is implemented, then the versatility and ease of installation are improved, but the device complexity increases

Engineering Contradiction:
ImproveversatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The tire monitoring system is divided into separate functional modules (pressure sensor module, temperature sensor module, transmitter module, etc.), each capable of independent installation and removal. This segmentation enables the system to achieve versatility through modular combinations while managing complexity by standardizing interfaces between modules and the base structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements universal mechanical attachment elements and electrical contacts that work across all module types. Each module uses the same attachment mechanism to connect to the base and to other modules, creating a multi-functional interface that simplifies the overall system despite the diversity of sensor functions available.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple sensor modules are stacked and mechanically attached, then the functionality and measurement capabilities are improved, but the installation complexity increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The mechanical attachment elements and electrical contacts are pre-configured on each module during manufacturing, ensuring proper alignment and connectivity. This preliminary preparation eliminates the need for complex field assembly procedures, as modules can be directly stacked and connected without additional adjustment or wiring work.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The base structure serves as an intermediary platform that provides standardized mechanical support and electrical connectivity for all modules. This intermediary base simplifies installation by absorbing the complexity of mounting to the tire, allowing modules to be simply attached to the base rather than requiring direct installation to the tire structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of repair

If interchangeable modules with standardized attachment elements are used, then the ease of repair and replacement are improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveease of replacementVSAvoidmanufacturing precision
Core Design Contradiction:
Ease of repairVSManufacturing precision

Solution Approach 1:

The patent employs standardized mechanical attachment elements with defined geometric parameters and tolerances that balance interchangeability requirements with manufacturing feasibility. By establishing specific parameter ranges for attachment element dimensions and tolerances, the system achieves easy module replacement while maintaining realistic manufacturing precision requirements.

Inventive Principle:
Principle #35Parameter changes

AI summary

An electronics assembly includes a base and a plurality of modules. The base is configured for mechanical attachment to a tire. The base includes an electronic device, and also includes a mechanical attachment element. Each module includes an electronic device, a lower mechanical attachment element, and an upper mechanical attachment element. The lower mechanical attachment element on each one of the modules is configured for attachment to the upper mechanical attachment element on any other one of the modules. In this configuration, the modules are interchangeably mechanically attachable to each other in a stacked arrangement. Each lower mechanical attachment element is also configured for attachment to the mechanical attachment element on the base. The modules are thus mechanically attachable to the base interchangeably with each other, which enables any one of the modules to be installed as the lowermost module in the stacked arrangement.
