Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a stepped rim with discrete steps is used on the center ring, then mechanical resistance and assembly stability are improved, but the rotational position of the burner is restricted to limited angle positions
Solution Approach 1:
The invention changes the geometric parameter of the center ring from a stepped rim with discrete steps to a flat rim with continuous surface. This parameter change allows the burner pin to rest at any angular position rather than being constrained to specific discrete positions, thereby improving installation flexibility while maintaining assembly stability through the elastic component's securing action.
Solution Approach 2:
The invention introduces a dynamic adjustment capability by replacing the static stepped rim structure with a flat rim that allows continuous rotation. The burner can be rotated to any desired angle and secured in position, transforming the system from a fixed discrete-position mechanism to a continuously adjustable dynamic system.
2Strength
If a stepped rim with valleys is used on the center ring, then mechanical resistance is improved, but the burner pin requires special curved profiles matching the valleys
Solution Approach 1:
The invention simplifies the manufacturing process by changing the rim profile from a complex stepped structure with valleys to a simple flat rim. This eliminates the need to machine or mold complex curved profiles on the burner pin, allowing for easier and more cost-effective manufacturing of both the center ring and burner components while maintaining mechanical resistance through the elastic component.
Solution Approach 2:
The invention extracts and removes the complex stepped structure and matching valleys from the design. By eliminating these unnecessary geometric features, the design achieves mechanical resistance through a simpler flat rim configuration combined with an elastic securing component, thereby reducing manufacturing complexity.
3Illumination intensity
If two LEDs are used in the LED bulb, then omni-directional light emission is improved, but the burner rotation is constrained to limited positions
Solution Approach 1:
The invention changes the angular parameter constraint by replacing the stepped rim that limits rotation to discrete positions with a flat rim that enables continuous rotation. This allows the burner with two LEDs to be oriented at any angle to optimize light distribution, improving installation flexibility while maintaining the omni-directional light emission capability.

AI summary
The present invention relates to the field of lighting, and particularly to a retrofit LED bulb (10). The LED bulb (10) comprises a burner (11), an elastic component (12), and a center ring (13). The burner (11) comprises a first pin (1131). The center ring (13) comprises a central opening (130), a first flat rim (1311), and a first notch (1321). The burner (11) is inserted through the central opening (130) on assembly of the LED bulb (10). The first flat rim (1311) extends along a first part of an outer edge of the central opening (130). The first notch (1321) is cut-out beyond the central opening (130) at an end of the first flat rim (1311), and allows the first pin (1131) of the burner (11) to pass through on insertion of the burner (11). The elastic component (12) is configured to press the first flat rim (1311) of the center ring (13) against the first pin (1131) of the burner (11) after assembly of the LED bulb (10), so that an unintentional rotation between the burner (11) and the center ring (13) is inhibited.
