Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional trailer lighting systems are used, then basic illumination is provided, but the systems lack durability and are easily damaged by forklifts during loading/unloading
Solution Approach 1:
The lighting system is divided into modular components including individual light bars, power boxes, and battery packs that can be independently installed and replaced. This segmentation allows the system to be more resilient as individual components can be protected or replaced without compromising the entire system.
Solution Approach 2:
The patent implements different mounting strategies for different components - light bars are positioned high on the trailer interior walls away forklift traffic, while power boxes are secured to structural elements. Each component is placed in locations optimized for its specific protection needs.
2Adaptability or versatility
If conventional lighting systems are installed, then illumination is provided, but the systems lack configurability and cannot be easily customized
Solution Approach 1:
The lighting system uses discrete, modular light bars and power boxes that can be independently configured. Users can select and install the specific number and arrangement of light bars needed for their trailer size and lighting requirements, creating custom configurations without complex wiring harnesses.
Solution Approach 2:
The power box serves multiple functions - it houses the battery, provides power distribution to multiple light bars, and includes mounting capabilities. This multi-functionality reduces the number of separate components needed and simplifies the overall system configuration.
3Ease of operation
If conventional lighting systems are used, then basic lighting is provided, but the systems are tethered and cannot function when the trailer is detached from the tractor
Solution Approach 1:
The battery power source is extracted from the tractor and relocated into a self-contained power box that can be mounted on the trailer itself. This extraction allows the lighting system to operate independently when detached from the tractor, while still being able to draw power from the tractor when connected.
Solution Approach 2:
The power box is designed to accept power input from multiple sources - it can draw power from the tractor when connected via the electrical connector, or operate autonomously from its internal battery when detached. This dual-power capability provides universal operation in both tethered and untethered states.
4Reliability
If conventional lighting systems are installed, then illumination is provided, but the systems are susceptible to temperature extremes and condensation
Solution Approach 1:
The power box and light bar housings are sealed to protect internal electronics from moisture and condensation. This sealing creates a protective barrier that shields sensitive electrical components from the harsh trailer environment including temperature extremes and humidity.
Solution Approach 2:
Electronics are extracted from the light bars and consolidated into the sealed power box environment, which is better protected from temperature extremes and condensation. This centralization of sensitive components in a protected environment improves overall environmental resistance.
5Ease of manufacture
If conventional lighting systems are used, then basic illumination is provided, but the systems are difficult to install and maintain
Solution Approach 1:
The lighting system is divided into self-contained modules - light bars with integrated mounting hardware and power boxes with pre-configured wiring. This segmentation allows for tool-free or minimal-tool installation using simple mounting brackets and connectors, significantly reducing installation complexity.
Solution Approach 2:
The modular components are pre-assembled and pre-wired during manufacturing, with mounting brackets and connectors pre-attached. This preliminary preparation eliminates the need for complex field assembly and wiring, making installation straightforward and maintenance simple.
6Use of energy by moving object
If conventional lighting systems are installed, then illumination is provided, but the systems consume excessive energy and require frequent recharging
Solution Approach 1:
The system uses motion-activated or presence-based lighting control where light bars can be turned on individually based on activity detection. This periodic activation rather than continuous operation reduces energy consumption while maintaining adequate lighting during loading/unloading operations.
Solution Approach 2:
Individual light bars can be independently controlled and activated, allowing the system to illuminate only the specific areas where work is being performed rather than the entire trailer. This selective activation improves energy efficiency and extends battery duration.
