Rotatable Lamp Cover Cap for Socket Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lamp systems face issues when replacing fluorescent tube lamps, as the directional light emission of LED bulbs does not align with the current-carrying position of standard fluorescent tube sockets, leading to inefficient light distribution, especially in ceiling-mounted sockets, which require extensive conversion to direct light towards the floor.
Innovation Solution
A lamp system with a cover cap featuring a separable adapter piece and contact pins that can be adjusted in position by 90°, allowing for flexible alignment of light emission without disconnecting the contact pins from the electronics, using a Swiss cross recess and fixing pins for secure positioning and a crimp connection for a durable cable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED light sources use standard fluorescent tube sockets, then the insertion mechanism is compatible, but the directional light emission does not align with the current-carrying position of the socket
Solution Approach 1:
The cover cap is divided into a base element and a detachable adapter piece that can be rotated independently. This segmentation allows the adapter to be positioned at different angles (0° or 90°) to align the contact pins with the socket's current-carrying position while maintaining compatibility with standard fluorescent tube sockets.
Solution Approach 2:
The adapter piece is designed to be rotatable relative to the base element, enabling dynamic adjustment of the contact pin orientation. This dynamic mechanism allows users to change the position of the contact pins by 90° to match different socket configurations without replacing the entire light source.
2Adaptability or versatility
If the socket is wall-mounted or ceiling-mounted with rotated live position, then the installation flexibility is improved, but the LED light cannot be emitted in the desired direction
Solution Approach 1:
The rotatable adapter piece enables dynamic repositioning of the contact pins to match any socket orientation. Whether the socket is wall-mounted or ceiling-mounted with the live position rotated by 90°, the adapter can be rotated accordingly to ensure the LED light emits in the desired direction without requiring socket modification.
3Ease of operation
If the contact pins are repositioned to align with the socket, then the light emission direction is improved, but the connection between contact pins and electronics must be disconnected
Solution Approach 1:
The cover cap is segmented into a base element containing the electronics and a detachable adapter piece containing the contact pins. This segmentation allows the adapter to be rotated independently without disconnecting the internal cable connections, simplifying the repositioning process while maintaining electrical continuity.
Solution Approach 2:
The intermediate layer with the Swiss cross recess acts as a mediator between the base element and the adapter piece. It provides a mechanical interface that allows the adapter to be rotated and repositioned while maintaining the connection between the contact pins and the electronics through the flexible cable.
4Adaptability or versatility
If a detachable adapter piece is used to adjust contact pin position, then the alignment flexibility is improved, but the device structure becomes more complex
Solution Approach 1:
The cover cap is divided into a base element and a detachable adapter piece, allowing the adapter to be independently positioned. This segmentation provides the necessary alignment flexibility while keeping each component relatively simple in structure.
Solution Approach 2:
The adapter piece is inserted into the base element, with the intermediate layer nesting between them. The Swiss cross recess in the intermediate layer provides a mechanical interface that guides and secures the adapter in specific positions (0° or 90°), enabling position adjustment while maintaining a compact integrated structure.
5Stability of the object's composition
If the adapter is securely fixed in position, then the alignment stability is improved, but the ability to reposition the contact pins is reduced
Solution Approach 1:
The adapter piece is designed with dynamic fixation: it can be easily inserted and rotated to different positions (0° or 90°) through the Swiss cross recess mechanism, and once positioned, it is securely held in place. This provides both repositioning capability and position stability when needed.
Solution Approach 2:
The intermediate layer with the Swiss cross recess is pre-configured with stop tabs and recesses that guide the adapter into the correct positions before final engagement. This preliminary guidance ensures accurate positioning while allowing the user to select between different stable positions (0° or 90° rotation).
