Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED lamp beads are mounted on frameworks by drilling bores, then lighting effect is achieved, but structural strength deteriorates and assembly becomes time-consuming
Solution Approach 1:
The framework is divided into modular components with pre-formed light-emitting segments. Each segment contains integrated LED lighting elements that can be independently assembled, eliminating the need for drilling bores through the entire framework structure and preserving structural integrity while achieving lighting functionality.
Solution Approach 2:
The lighting elements are merged with the framework structure into integrated light-emitting segments. The LED lamp beads, supporting structures, and framework components are combined into unified modular units that maintain structural strength while providing lighting functionality without requiring separate drilling and mounting operations.
2Illumination intensity
If numerous LED lamp beads are used to achieve good lighting effect, then illumination is improved, but wiring circuits become excessive and mounting complexity increases
Solution Approach 1:
The lighting system is segmented into modular light-emitting units, each containing integrated wiring and LED components. This segmentation allows independent assembly and simplifies the overall wiring architecture by breaking down complex continuous wiring into manageable modular connections.
Solution Approach 2:
The modular light-emitting segments are designed as universal components that can be applied to different framework positions and configurations. Each module contains integrated wiring solutions that can be standardized across the entire umbrella structure, reducing overall wiring complexity while maintaining lighting effectiveness.
3Illumination intensity
If individual lamp beads are mounted separately in bores, then lighting coverage is achieved, but maintenance becomes difficult and time-consuming
Solution Approach 1:
The lighting system is segmented into modular light-emitting units that can be independently removed and replaced. This segmentation enables maintenance personnel to access and replace specific lighting modules without disassembling the entire framework, significantly improving maintenance convenience while maintaining comprehensive lighting coverage.
Solution Approach 2:
The light-emitting segments are pre-assembled with all necessary wiring, mounting components, and LED elements before installation. This preliminary assembly reduces on-site maintenance complexity by providing self-contained modular units that can be quickly swapped without requiring complex wiring work or specialized tools.
4Ease of manufacture
If drilling bores is performed on every framework component, then LED mounting is achieved, but production time and labor consumption increase
Solution Approach 1:
The manufacturing process is segmented into separate operations: framework assembly and light-emitting module assembly occur independently, then modules are integrated. This eliminates the need for drilling bores during framework assembly, allowing parallel production and significantly improving overall manufacturing productivity while maintaining LED mounting capability.
Solution Approach 2:
Light-emitting modules are pre-assembled and tested before integration with the framework. This preliminary preparation of modular components allows for streamlined final assembly without time-consuming drilling and mounting operations during main production, thereby increasing assembly speed and productivity.
