Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional RFID labels are used on vehicles, then they can provide identification functionality, but they degrade rapidly due to ultraviolet radiation exposure

Engineering Contradiction:

Improvelabel durabilityVSAvoidultraviolet radiation damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies UV-resistant inks and materials that not only protect against UV damage but also maintain their identification and printing functions. The UV-resistant properties are converted into a beneficial protective feature while preserving the original label functionality, allowing the label to withstand prolonged sun exposure without degrading.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The RFID label is constructed as a composite structure with multiple layers including UV-resistant base materials, UV-resistant inks for printing, and UV-protected adhesive layers. This composite approach combines materials with different UV protection properties to create a multi-layered defense system that protects the electronic components and antenna from ultraviolet radiation while maintaining overall label functionality.

Inventive Principle:

Principle #40Composite materials

2Reliability

If UV-resistant materials are used to protect against ultraviolet radiation, then the label durability is improved, but the manufacturing complexity increases

Engineering Contradiction:

Improvelabel durabilityVSAvoidmanufacturing process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges UV protection functionality with the existing label manufacturing process by integrating UV-resistant inks and materials into standard printing and lamination steps. The UV-resistant properties are combined with the identification, printing, and adhesive functions in a unified label structure, allowing simultaneous production of multiple functions without requiring separate manufacturing processes.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent modifies the chemical and physical parameters of the materials used in label construction by selecting materials with inherent UV-resistant properties. This includes using inks and coatings with UV absorption characteristics and base materials that resist UV degradation, thereby changing the material parameters to provide protection without fundamentally altering the manufacturing process architecture.

Inventive Principle:

3Reliability

If multiple UV-resistant layers are added to the RFID label, then the protection against ultraviolet radiation is enhanced, but the label thickness and weight increase

Engineering Contradiction:

ImproveUV radiation resistanceVSAvoidlabel weight

Core Design Contradiction:

ReliabilityVSWeight of stationary object

Solution Approach 1:

The patent employs thin-film UV-resistant coatings and laminates that provide effective ultraviolet protection with minimal thickness. These thin films are applied as protective layers over the label components, offering UV shielding while maintaining the label's flexibility and keeping the weight increase to a minimum. The thin-film approach allows UV protection without adding significant mass or rigidity.

Inventive Principle:

Principle #30Flexible shells and thin films
