Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If board mounted LEDs are used in LED lamps, then the lighting efficiency and lifetime are improved, but the electrical components become exposed creating safety hazards
Solution Approach 1:
The patent applies nesting by placing the LED within a socket structure that is enclosed by a decorative light shade. The socket itself is mounted within a fixture housing, creating multiple nested layers of protection. This nested structure allows the LED to benefit from the long lifetime of board-mounted LEDs while being physically protected from exposure, thereby eliminating the safety hazard.
Solution Approach 2:
The socket and decorative light shade serve as intermediary elements between the LED and the user environment. These intermediaries provide physical barriers that prevent direct contact with electrical components while still allowing the LED to function effectively. The socket acts as an immediate protective enclosure, and the decorative light shade provides an additional layer of protection and aesthetic coverage.
2Use of energy by moving object
If compact fluorescent bulbs are used, then the energy efficiency is improved compared to incandescent bulbs, but the color temperature is not aesthetically pleasing and dangerous gasses are contained
Solution Approach 1:
The patent utilizes the ability of LEDs to emit light at a wide variety of color temperatures, allowing selection of parameters that are both energy-efficient and aesthetically pleasing. By changing the color temperature parameter of the LED light source, the fixture can provide the energy efficiency of modern lighting while eliminating the unpleasant color temperature issue associated with compact fluorescent bulbs.
Solution Approach 2:
The patent replaces compact fluorescent bulbs (which contain dangerous gasses like mercury) with LED technology. LEDs do not contain hazardous materials and have longer lifetimes, eliminating both the gas containment issue and the aesthetic color temperature problems while maintaining high energy efficiency.
3Shape
If the decorative light shade is made translucent, then the aesthetic appearance is improved, but the electrical components may still be visible or accessible
Solution Approach 1:
The patent uses a nested structure where the opaque or translucent socket is placed inside the decorative light shade. This nested arrangement ensures that even if the light shade is translucent, the socket structure provides an additional barrier that conceals electrical components. The multi-layer nesting approach maintains aesthetic appearance while preventing visibility and access to hazardous elements.
Solution Approach 2:
The socket structure serves as an intermediary barrier between the electrical components and the external environment. Even when the decorative light shade is translucent, the socket provides an additional layer of concealment and protection, acting as a mediator that prevents direct visibility or access to electrical components while still allowing light to pass through the overall assembly.
