Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If array-arranged LED lamp beads are used to create dynamic lighting effects, then diverse lighting modes are achieved, but manufacturing and design costs increase due to large quantity of LED lamp beads required

Engineering Contradiction:
Improvelighting modesVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies multi-functionality by enabling a single LED lamp bead to perform multiple lighting functions through mechanical movement. The movable blocking structure allows one LED to create various lighting effects (daytime running light, turn signal, position light, etc.) that would traditionally require multiple separate LED arrays, thereby reducing the total number of LEDs needed and lowering manufacturing costs while maintaining diverse lighting mode capability

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

Solution Approach 2:

The patent implements dynamics by introducing a movable blocking structure that can change position to create different lighting effects. This mechanical movement allows a single static LED lamp bead to dynamically produce multiple lighting modes by controlling what portions of its light are blocked or exposed, replacing the need for multiple static LED arrays and reducing overall component quantity and cost

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If mechanical movement of decorative bezel is employed to block or expose luminous structures, then dynamic lighting effects are created, but functionality is limited and presentation is rigid

Engineering Contradiction:
Improvelighting functionalityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies multi-functionality by designing the movable blocking structure to work with a single LED lamp bead to achieve multiple lighting functions (daytime running light, turn signal, position light, welcome light, farewell light). This approach increases lighting functionality while keeping the mechanical structure relatively simple, avoiding the complexity of multiple separate mechanical systems

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

Solution Approach 2:

The patent merges the functions of multiple lighting systems into a single integrated structure. By combining the LED light source, movable blocking structure, and reflective surface into one unified assembly, the patent achieves diverse lighting functionality without requiring separate mechanical systems for each lighting mode, thereby reducing overall device complexity

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If numerous LED lamp beads are used to achieve dynamic lighting effects, then diverse lighting modes are provided, but device complexity and cost increase

Engineering Contradiction:
Improvelighting modesVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies multi-functionality by enabling a single LED lamp bead to perform multiple lighting functions through the movable blocking structure. This dramatically reduces the number of LED components needed while maintaining diverse lighting mode capability, thereby simplifying the overall device structure and reducing complexity

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

Solution Approach 2:

The patent uses a reflective surface to create optical copies of the LED light. The reflective surface bounces and redirects light from the single LED lamp bead to create multiple apparent light sources and various lighting patterns, effectively multiplying the light output without multiplying the physical LED components, thus reducing device complexity

Inventive Principle:
Principle #26Copying
