Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional patterns with straight ridges or identical three-dimensional shapes are arranged on the sidewall, then the manufacturing process is simple and easy to implement, but the visual effect is ordinary and lacks innovation
Solution Approach 1:
The decorative area is divided into multiple small planes (first, second, and third planes) with different inclinations, arranged in a segmented pattern. Each plane reflects light differently, creating a composite visual effect that is more complex than conventional single-shape patterns while remaining manufacturable through modular arrangement.
Solution Approach 2:
The pattern uses planes with different inclinations (first, second, and third planes at different angles) rather than identical repeating shapes. This asymmetric arrangement of planar surfaces creates varied light reflection angles, producing innovative visual effects that break the monotony of conventional symmetric patterns.
2Shape
If planes with different inclinations are arranged to create new visual effects, then the visual appeal and three-dimensional appearance are enhanced, but the pattern design and manufacturing complexity increases
Solution Approach 1:
The invention transitions from two-dimensional flat patterns to three-dimensional planar surfaces with different inclinations. By introducing angular dimensionality, the planes reflect light from multiple directions, creating a genuine three-dimensional appearance that enhances visual appeal while the modular planar structure keeps manufacturing feasible.
Solution Approach 2:
The invention changes the inclination angle parameter of each plane to create visual variety. By adjusting the inclination angles of the first, second, and third planes differently, the design achieves three-dimensional appearance without requiring complex curved surfaces, maintaining ease of manufacture through parameter variation rather than geometric complexity.
3Illumination intensity
If boundaries between planes are aligned in a regular pattern, then the manufacturing process is simplified, but the visual effect becomes repetitive and less appealing
Solution Approach 1:
The boundaries between adjacent planes are deliberately arranged asymmetrically rather than in straight aligned lines. This asymmetric boundary arrangement prevents repetitive visual patterns while the planes themselves maintain sufficient geometric precision for manufacturing. The visual interest comes from the boundary irregularity combined with planar symmetry.
Solution Approach 2:
By arranging planes at different inclinations with shifted boundaries, the invention creates visual complexity in the angular dimension rather than requiring precise linear alignment. This shifts the precision requirement from boundary straightness to planar inclination accuracy, which is more achievable and produces better visual effects.
