Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional LED light bulbs are used, then energy efficiency is improved, but design attractiveness and light quality are insufficient
Solution Approach 1:
The light bulb is divided into multiple elongated filaments arranged in a circular pattern, with each filament containing LED chips. This segmentation allows for improved light distribution and quality while maintaining the energy-efficient LED technology, resolving the contradiction between energy efficiency and design attractiveness.
Solution Approach 2:
The patent transitions from conventional single-filament LED bulbs to multiple elongated filaments arranged in three-dimensional space within the bulb housing. This dimensional change creates more attractive lighting patterns and improves light quality while preserving the energy efficiency of LED technology.
2Illumination intensity
If multiple elongated filaments with LED chips are used, then light quality is improved, but manufacturing complexity increases
Solution Approach 1:
The elongated filaments serve multiple functions: they provide structural support, serve as electrical conductors, and hold the LED chips in precise positions. This multi-functionality reduces the need for separate components, thereby reducing manufacturing complexity while maintaining improved light quality.
Solution Approach 2:
The patent combines the support structure, electrical connection, and chip mounting functions into a single integrated filament design. This merging of functions simplifies the manufacturing process while achieving the desired light quality improvement through the elongated geometry and LED chip arrangement.
3Ease of manufacture
If nickel wire brackets are used for structural support, then cost is reduced, but structural strength may be compromised
Solution Approach 1:
The patent uses thin nickel wire brackets that provide sufficient structural support for the LED chips while maintaining flexibility and cost-effectiveness. The wire configuration is designed to provide adequate strength for the application while using minimal material, resolving the contradiction between cost and structural strength.

AI summary
A light bulb apparatus includes a central column, a central bar, a top bracket, a bottom bracket, multiple elongated filaments and a bulb shell. The central column is made of glass material. The central column has a top part, a tubular part and a trumpet part. The top part and the trumpet part are located at two opposite ends of the tubular part. The central bar is extended from the central column upwardly. The top bracket has a limiting structure to limit a movement of the top bracket relative to the central bar. The bottom bracket is fixed to the central column. The multiple elongated filaments have bottom ends fixed to the bottom bracket and with top ends fixed to the top bracket. The bulb shell has a bottom edge fixed to the trumpet part forming a container space enclosing the bottom bracket and the multiple elongated filaments.
