Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed lighting apparatus is used, then the structure is simple and stable, but the light distribution is limited and cannot adapt to various scenarios
Solution Approach 1:
The patent applies the dynamics principle by making the light source units rotatable around multiple axes (first axis for horizontal rotation, second axis for vertical rotation). This dynamic adjustment capability allows the lighting apparatus to change light distribution patterns adaptively, transforming from a fixed structure to a versatile system that can serve multiple illumination scenarios.
Solution Approach 2:
The patent segments the lighting system into multiple independent light source units (first light source unit and second light source unit), each capable of independent rotation and adjustment. This segmentation enables each unit to be optimized for specific lighting tasks while maintaining overall system versatility without excessive complexity.
2Adaptability or versatility
If the lighting apparatus is made portable with detachable battery pack, then mobility and application range are improved, but the device complexity increases
Solution Approach 1:
The patent segments the lighting apparatus into distinct functional modules: a main body containing control circuitry, detachable light source units with rotation mechanisms, and a separate battery pack. This modular segmentation enables portable use while keeping each component relatively simple and independent.
Solution Approach 2:
The patent implements universality through the detachable battery pack design, allowing the same main body to function with different battery packs or in different locations. The universal coupling mechanism enables easy attachment and detachment, enhancing portability without requiring complex locking or attachment systems.
3Adaptability or versatility
If multiple light source units are added to achieve various light distributions, then the versatility is improved, but the device complexity and weight increase
Solution Approach 1:
The patent divides the lighting system into separate, lightweight light source units that can be independently attached and detached. Each unit contains its own rotation mechanisms and is optimized for minimal weight while providing specific lighting functions, allowing users to configure only the needed units for each scenario.
Solution Approach 2:
The patent employs dynamic rotation mechanisms that allow light source units to be repositioned without adding permanent structural weight. The rotation axes are integrated into the coupling structure, enabling flexible adjustment of light distribution patterns while maintaining overall apparatus lightweight design.

AI summary
An object of the present invention is to provide a lighting apparatus configured to realize various light distributions. A plurality of hinge devices (5) couple a plurality of light source units (3) to a base (2) such that the light source units (3) are rotatable around first axes. Each light source unit (3) is rotatable between a first position and a second position around a corresponding first axis of the first axes. A plurality of rotation mechanisms couple the light source units (3) to the hinge devices (5) such that the light source units (3) are rotatable around second axes transverse to the first axes. The hinge devices (5) are configured such that when each light source unit (3) rotates from the first position to the second position, rotation directions of the light source units (3) are different. The rotation mechanisms define rotation ranges of the light source units (3) around the second axes to achieve a reference state where the light source units (3) are collected together and light-outgoing surfaces (3222) of the light source units (3) face outward when each light source unit (3) is in the first position.
