Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple illumination devices are arranged adjacently to achieve uniform two-dimensional illumination, then the illuminated area increases, but maintaining consistent light distribution becomes difficult due to varying distances between light emitting elements

Engineering Contradiction:
Improveilluminated areaVSAvoiddistance consistency between light emitting elements
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The illumination system is divided into multiple separate illumination devices, each contributing a portion of the overall illuminated area. By segmenting the system, each device can be independently manufactured with precise spacing between its light emitting elements, and when arranged adjacently, they collectively form a uniform large-area illumination pattern.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent specifies precise parameter relationships: the distance between light emitting elements in adjacent illumination devices is set to 0.5 to 1.5 times the distance between neighboring elements within one device. This parameter control ensures that when devices are arranged adjacently, the overall distance pattern remains consistent, achieving uniform illumination across the expanded area.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If fixed illumination arrays are used to achieve uniform illumination, then illumination uniformity is improved, but flexibility to adapt to different area sizes is restricted

Engineering Contradiction:
Improveillumination uniformityVSAvoidflexibility for different area sizes
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The system transitions from a fixed, monolithic array to a dynamic, modular configuration. Multiple illumination devices can be independently positioned and arranged adjacently to create uniform illumination for different area sizes. The pivotable design allows the illumination unit to rotate about a longitudinal axis, enabling adaptation to various spatial requirements while maintaining illumination uniformity through controlled arrangement.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Each illumination device is designed as a universal module that can function independently or be combined with other identical devices. The standardized design with specific spacing relationships allows the same device type to serve multiple purposes: single-device operation for small areas and multi-device arrays for large areas, providing versatility across different application scenarios.

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

3Area of stationary object

If individual spots are positioned adjacently to achieve uniform illumination, then the illuminated area can be covered, but the positioning process becomes laborious and time-consuming

Engineering Contradiction:
Improveilluminated areaVSAvoidpositioning time
Core Design Contradiction:
Area of stationary objectVSLoss of time

Solution Approach 1:

Multiple individual spot illuminators are merged into a single integrated illumination device with multiple light emitting elements arranged in a specific pattern. This combination allows the device to cover a larger area in one unit, eliminating the need to individually position multiple separate spots and significantly reducing installation time while maintaining uniform illumination coverage.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The light emitting elements are pre-positioned at precise intervals within each illumination device during manufacturing. This preliminary arrangement of elements at correct spacing eliminates the need for time-consuming on-site positioning and adjustment, allowing for rapid deployment while ensuring uniform illumination patterns when devices are arranged adjacently.

Inventive Principle:
Principle #10Preliminary action

AI summary

Embodiments provide an illumination device comprising an elongated base and a pivotable elongated illumination unit. Said pivotable elongated illumination unit is mounted to be pivotable about a longitudinal axis by means of at least one joint. Both the elongated base and the pivotable elongated illumination unit extend in parallel with said longitudinal axis. In particular, the longitudinal extension of the pivotable elongated illumination unit is limited by two opposing lateral faces. The illumination unit includes at least two illumination elements arranged along the pivotable axis, so that a distance between two neighboring light emitting elements corresponds to 1.5 to 2.5 times the distance between a light emitting element that is positioned adjacently to a lateral face and the corresponding lateral face.
