Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bulbs with adjustable color temperature and color are used, then light output adjustability is improved, but assembly space requirement increases
Solution Approach 1:
The illumination body is divided into multiple light directing devices (102-114), each with its own light emitting element and optical components. This segmentation allows each module to be compact while the collective system provides comprehensive light control across different angles and color temperatures.
Solution Approach 2:
The light emitting element is integrated directly into the light directing device, with the collimation portion and prism portion nested within the same housing. This nested arrangement eliminates the need for separate assemblies and reduces overall space requirements while maintaining full adjustability functionality.
2Ease of operation
If spots with mechanically adjustable angle are used, then light angle control is improved, but device complexity increases
Solution Approach 1:
The patent replaces mechanical adjustment mechanisms with optical redirection. Light emitting elements are positioned at specific angles relative to the illumination body, and prism portions redirect light at predetermined angles. This eliminates mechanical moving parts while providing precise angle control through fixed optical geometry.
Solution Approach 2:
The light emitting elements are pre-positioned at specific angles during manufacturing, and the prism portions are pre-configured to redirect light at desired angles. This preliminary arrangement of optical components eliminates the need for runtime mechanical adjustments, simplifying the device while maintaining operational flexibility.
3Adaptability or versatility
If LED-based luminaries with full adjustability are used, then light output versatility is improved, but assembly space requirement increases
Solution Approach 1:
The patent merges the light emitting element, collimation portion, and prism portion into a single integrated light directing device. This consolidation combines multiple previously separate components into one compact unit, reducing assembly space while preserving the full versatility of adjustable color temperature, color, and light angle control.
Solution Approach 2:
Each light directing device serves multiple functions: it emits light, collimates the light rays, redirects light at specific angles, and can be controlled for dimming and switching. This multi-functionality eliminates the need for separate components for each function, reducing overall assembly space while maintaining comprehensive light output versatility.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a compact, versatile lighting solution that can be adjusted for different angles and areas of illumination, enhancing optical comfort and usability, while reducing assembly space requirements and allowing for seamless integration with modern electronic controls.
Implementation Method 1
At least one light directing device comprises a collimation area in which the light rays of the light emitting element, which is arranged on the light directing device, are parallelized
Implementation Method 2
at least one prism portion each of which redirects one part of the parallelized light rays
Implementation Method 3
The inclined area of a part of the light directing device may reflect the parallelized light
Implementation Method 4
The inclined area of a part of the light directing devices may refract the parallelized light. The latter may be the case if the angle of the collimation portion with respect to the parallelized light rays is lower that the critical angle
