Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a tire module is attached to the inside of a pneumatic tire using conventional methods, then the attachment is initially secure, but the tire module starts to detach after longer periods of operation

Engineering Contradiction:
Improveattachment reliabilityVSAvoidservice life of attachment
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent applies parameter changes by controlling temperature, pressure, and time during the vulcanization process. The setting head delivers controlled pressure (via pneumatic cylinder) and temperature (via heating element) to achieve proper bonding between the tire module and tire inner surface, ensuring long-term attachment reliability without detachment.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces simple mechanical attachment with vulcanization bonding. Instead of relying on mechanical fastening that may loosen over time, the tire module is chemically bonded to the tire inner surface through controlled vulcanization, creating a permanent bond that maintains reliability throughout the tire's service life.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If conventional attachment methods are used for tire modules, then the process is simple, but the attachment lacks reproducibility and uniformity

Engineering Contradiction:
Improveattachment process simplicityVSAvoidattachment uniformity
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent incorporates feedback control through sensors that monitor temperature, pressure, and position during the attachment process. The control unit adjusts parameters in real-time to maintain consistent bonding conditions, ensuring reproducible and uniform attachment quality across all tire modules while keeping the process automated and manageable.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The setting head is designed to be movable and adjustable, allowing dynamic adaptation to different tire sizes and positions. The pneumatic cylinder provides controlled, variable pressure, and the heating element delivers adjustable temperature, enabling the system to maintain optimal bonding conditions throughout the process for consistent results.

Inventive Principle:
Principle #15Dynamics

3Strength

If tire modules are fastened with strong bonding, then attachment security is improved, but the modules cannot be easily removed and replaced

Engineering Contradiction:
Improvebond strengthVSAvoidmodule replaceability
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The patent applies local quality by designing the tire module with a specific peripheral edge structure that concentrates the bonding area. The vulcanization bond is created locally at the peripheral edge and contact surface, providing strong attachment where needed while leaving other areas accessible for removal and replacement operations.

Inventive Principle:
Principle #3Local quality

4Manufacturing precision

If a complex automated pressing system is used for tire module attachment, then manufacturing precision is improved, but device complexity increases

Engineering Contradiction:
Improvecentral and uniform pressingVSAvoidsystem structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The setting head is designed as a multi-functional device that combines holding, heating, and pressing functions in a single component. The hollow cylinder structure serves both as a heating element and as a pressing tool, while the pneumatic cylinder provides both positioning and bonding pressure, reducing overall system complexity while maintaining precision.

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

AI summary

In the case of a mounting device (1) for securing a tyre module (2), in particular a tyre pressure sensor, to an inner side of a pneumatic tyre for vehicles, comprising a stand (11) from which there extends a supporting arm (12), wherein a setting head (14) that can be lowered with a predeterminable force is attached to the longitudinal end of the supporting arm (12) that is remote from the stand (11), the intention is to provide a solution by which a tyre module can be reproducibly secured to an inner side of a pneumatic tyre of a vehicle in a structurally simple way. This is achieved by the setting head (14) having a holding device (39), with which the tyre module (2) can be releasably held in a clamping way on the setting head (14) during the securement, and having at least one heating element (36) for connecting the tyre module (2) to the inner side of the pneumatic tyre in a material-bonded manner.
