Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If light affecting elements are formed using 3-D printing, then manufacturing cost and time are reduced, but the aesthetic visual effect is insufficient

Engineering Contradiction:
Improvemanufacturing costVSAvoidaesthetic visual effect
Core Design Contradiction:
Ease of manufactureVSIllumination intensity

Solution Approach 1:

The optical component is divided into multiple layers with different transmissivity characteristics (first regions with lower transmissivity, second/third regions with higher transmissivity). This segmentation allows each layer to manipulate light differently, creating complex angularly-dependent visual effects that are aesthetically pleasing while maintaining 3-D printed construction

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from conventional planar or simple 3-D printed light diffusers to multi-layered structures with staggered transmissive portions. By adding the dimensional complexity of layered stacking with horizontal offsets, the system creates passage regions that enable dynamic light effects varying with viewing angle, thus improving aesthetic visual effect while maintaining manufacturability through 3-D printing

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If conventional light sources are used, then simplicity is maintained, but dynamic light effects are not achieved

Engineering Contradiction:
Improvestructure simplicityVSAvoiddynamic light effects
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The optical component creates dynamic light effects by utilizing the interaction between light sources and the multi-layered structure. The staggered arrangement of transmissive portions causes the light pattern to change dynamically with viewing angle, providing adaptability and versatility in lighting effects without requiring complex active control systems or multiple light sources

Inventive Principle:
Principle #15Dynamics
