Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a random distribution of heterogeneities in transparent material is used for identification, then authentication can be performed, but the manufacture becomes long and complex requiring meltable material, dispersing means, and solidification mold

Engineering Contradiction:
Improveauthentication capabilityVSAvoidmanufacturing process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention changes the state of particles from requiring melting and solidification to simply being compressed. Solid particles are placed in a cavity and compressed under pressure to form the identifier, eliminating the need for phase changes and complex molding processes while maintaining the random distribution pattern for authentication

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention replaces the thermal-mechanical system (melting, dispersing, solidification) with a purely mechanical compression system. Particles are compressed under pressure between a first wall and second wall to form the identifier pattern, significantly simplifying the manufacturing process

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

2Ease of manufacture

If heterogeneities are dispersed in meltable material with solidification mold, then identifier can be formed, but the process is time-consuming and not aesthetically suitable for luxury items

Engineering Contradiction:
Improveidentifier formation capabilityVSAvoidmanufacturing time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The invention eliminates phase change processes (melting and solidification) by using solid particles that are simply compressed. This reduces manufacturing time significantly while allowing for aesthetic presentation through transparent or translucent materials that can be viewed without complex molding

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention extracts and eliminates the time-consuming steps of melting, dispersing heterogeneities in liquid material, and solidification. Only the essential function of forming a random pattern is retained through direct compression of solid particles

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If solid particles are compressed against transparent material, then a stable and tamper-proof identification pattern is generated, but the device structure becomes more complex with compression wall and activation means

Engineering Contradiction:
Improvetamper-proof identificationVSAvoidcoding means structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention merges the compression wall with the cylinder to form an integrated hollow compartment structure. The activation means are integrated into this compartment, reducing the number of separate components while maintaining the tamper-proof compression mechanism for generating the identification pattern

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If a random distribution pattern is used for authentication, then uniqueness is achieved, but the manufacturing process requires multiple steps including material preparation, heterogeneity dispersal, and molding

Engineering Contradiction:
Improveunique identification capabilityVSAvoidproduction simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The invention changes the manufacturing approach from multi-step processes involving material preparation and molding to a single-step compression process. Solid particles with random properties (size, shape, color) are simply compressed to form the unique identifier, maintaining adaptability while greatly simplifying production

Inventive Principle:
Principle #35Parameter changes
