Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional string lights are used for outdoor ornamental lighting, then engaging imagery can be provided, but installation becomes difficult and dangerous requiring ladders and posing safety hazards
Solution Approach 1:
The lighting system is divided into multiple individual projector heads that can be independently installed and controlled. Each projector head is a separate unit that can be mounted on stakes or other surfaces, eliminating the need to work at heights with traditional string lights. The segmentation allows for ground-level installation while achieving comprehensive lighting coverage.
Solution Approach 2:
The patent introduces stakes as intermediary mounting elements that transfer the lighting function from overhead installation to ground-level installation. The stakes serve as mediators between the ground and the projector heads, allowing safe installation without ladders while maintaining the desired lighting effects.
2Illumination intensity
If traditional ornamental lighting is used, then lighting effects can be achieved, but energy consumption is considerable and inefficient
Solution Approach 1:
The projector heads can be operated in sequences and patterns, illuminating different areas at different times. This periodic action allows the system to achieve engaging lighting effects while consuming less energy overall, as not all projectors need to operate at full intensity simultaneously. The programmable controllers enable energy-efficient scheduling and pattern management.
Solution Approach 2:
The system allows for dynamic adjustment of lighting parameters including intensity, color, and timing. By changing these parameters based on needs, the system can achieve high illumination intensity when required while operating at lower energy consumption during other periods, optimizing the balance between lighting effect and energy efficiency.
3Area of stationary object
If traditional string lights are installed on tall structures, then comprehensive coverage can be achieved, but installation requires ladders and becomes difficult
Solution Approach 1:
The patent transitions from vertical overhead installation to horizontal ground-level installation by using stakes. This dimensional change allows the lighting system to cover large areas through the arrangement and positioning of multiple ground-mounted projectors, achieving comprehensive coverage without the complexity of tall structure installation.
4Adaptability or versatility
If multiple projector heads are used to project different images, then dynamic visual effects can be created, but system complexity increases
Solution Approach 1:
Each projector head is designed as a universal unit capable of projecting different images and patterns. The standardized design with interchangeable components allows multiple projectors to work together as a coordinated system, achieving versatile dynamic visual effects while managing complexity through modularity and standardization.

AI summary
A projection light source system and method of manufacture are shown in various embodiments. In one embodiment a single projector head (12) includes a light source (95) which projects through a condenser lens (90) and then an image transparency 120 which may be film or other digital media, and through an imaging lens 140 which is adjustable by rotation of a threaded cap 150. Adjustment of the image target location is achieved in part via an adjustment in the flange (20) which is rotatably connected to the head. Sequencing of images from a plurality of heads which are internally, remotely or IP controllable creates the ability project a succession of fixed images from a succession of heads either overlapping their target point or adjacent to create the effect of motion.
