Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a lampshade is used to direct light, then glare is reduced, but the view of the surface is significantly covered and device complexity increases
Solution Approach 1:
The patent replaces the mechanical lampshade structure with an optical system consisting of multiple reflectors and LED light sources. This substitution eliminates the need for a bulky lampshade while achieving glare reduction through optical design, directly resolving the contradiction between glare reduction and structural simplicity.
Solution Approach 2:
The patent uses multiple reflectors with different emission angles to create zones of light with different characteristics. By directing light locally to specific areas rather than using a general lampshade, the system reduces glare in the user direction while maintaining visibility of the surface, resolving the contradiction between glare reduction and view coverage.
2Adaptability or versatility
If the light source is made movable to adjust beam geometry, then light distribution is improved, but device complexity and reliability worsen
Solution Approach 1:
The patent segments the lighting system into multiple independent reflector units, each with its own LED light source. By segmenting the system into static modular components rather than using a single movable light source, the patent achieves light beam geometry adjustment through selective activation of different segments, eliminating mechanical moving parts and improving reliability.
Solution Approach 2:
The patent achieves dynamic light beam geometry adjustment through electronic control of multiple static reflector units rather than mechanical movement. The electronic switching between different reflector combinations provides dynamic adaptability without mechanical components, resolving the contradiction between adjustability and reliability.
3Duration of action of moving object
If a built-in battery is added for portable operation, then operating autonomy is extended, but device complexity and weight increase
Solution Approach 1:
The built-in battery serves multiple functions: it provides portable power for extended operating autonomy, acts as a stabilizing mass to prevent tipping, and enables the device to function in both portable and fixed modes. This multi-functionality justifies the added complexity by providing multiple benefits from a single component.
Solution Approach 2:
The battery serves as a counterweight to prevent the lamp from tipping over, especially when placed on uneven surfaces or when the light head is adjusted to certain positions. This stabilizing function offsets the negative impact of added weight by improving overall system stability and safety.
4Adaptability or versatility
If multiple reflectors with different emission angles are used, then light distribution adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent achieves light distribution adaptability by changing the emission angle parameter of different reflector units rather than using complex adjustable mechanisms. Each reflector is manufactured with a specific emission angle, and the system provides adaptability by selectively combining different angle reflectors. This approach simplifies manufacturing compared to creating adjustable reflectors, as each unit can be independently manufactured with fixed parameters.
