Lamp Socket Asymmetric Ribs Prevent Incorrect Bulb Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Swan-type lamp sockets are complex and costly to manufacture, and they allow the insertion of multiple bulb types, including incorrect orientations, which can lead to improper fitting and potential damage.
Innovation Solution
A lamp socket design featuring ribs on the socket housing that correspond to a key on the bulb, forming a key groove to prevent incorrect bulb insertion by catching on the ribs if the shape does not match, along with elastic holders and a reinforcing bead to secure the bulb in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple single-mold socket housing is used, then manufacturing cost is reduced, but the socket allows insertion of incorrect bulb types and orientations
Solution Approach 1:
The patent introduces asymmetric key structures on the bulb base and corresponding key grooves formed by ribs in the socket housing. This asymmetric design ensures that only bulbs with the correct key shape can be inserted in the proper orientation, preventing incorrect bulb types or reversed insertion while maintaining a simple single-mold manufacturing process for the socket housing.
2Reliability
If Swan-type socket structure is used, then bulb insertion correctness is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent merges the bulb-holding function and the orientation-restriction function into a single integrated socket housing structure. The ribs that form key grooves are directly molded as integral parts of the socket housing, combining the housing structure with the orientation-restriction mechanism, thereby reducing overall structural complexity compared to traditional Swan-type sockets.
3Reliability
If orientation-restriction features are added to the socket, then bulb insertion correctness is improved, but manufacturing process complexity increases
Solution Approach 1:
The orientation-restriction features (ribs forming key grooves) are pre-formed as integral parts of the socket housing through a single molding process. This preliminary formation of restriction features during the basic manufacturing process eliminates the need for separate assembly steps or post-processing, thereby maintaining manufacturing simplicity while ensuring bulb insertion correctness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures that only a specific bulb can be inserted correctly, preventing damage and ensuring proper alignment, thus reducing manufacturing costs and improving reliability.
Implementation Method 1
elastic lamp holders are fixed that adhere to the base and hold it in place
Implementation Method 2
On one side of the inner wall support part, a reinforcing bead is formed protruding outward, so as to reinforce the supporting strength of the inner wall support part

AI summary
The disclosure relates to a lamp socket, and more specifically to a lamp socket so configured as to restrict the insertion of bulbs other than the intended bulb, by arranging ribs on the socket housing corresponding to the shape of a key formed on the bulb. The lamp socket of the disclosure is configured so that when the base of a bulb is inserted into the receiving space of the socket housing, the key formed on the base is not interfered with by the ribs arranged in the receiving space, while if the shape of the key does not match the pattern in which the ribs are arranged, the key will be caught on the ribs, preventing the insertion of the base.
