Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp sockets suffer from wires being easily pulled out due to inadequate fixation, posing safety hazards.
Innovation Solution
A lamp socket design featuring a connecting seat with a threaded section and an accommodating portion, where a conductive wire with a limiting portion is securely fixed through a thread gap, enhancing stability by increasing frictional force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the wire is simply sandwiched between the connecting seat and the lamp cap, then the structure is simple, but the wire cannot be firmly fixed and is easily pulled out
Solution Approach 1:
The wire is divided into multiple segments: the conductive section, the limiting portion with enlarged cross-section, and the insulated portion. The limiting portion is further segmented into regions with different radial dimensions. This segmentation allows the wire to have different functional zones that work together to prevent pull-out while maintaining overall structural simplicity.
Solution Approach 2:
The limiting portion of the wire is designed with an enlarged cross-sectional area in the radial direction, creating a dimensional change from the thin conductive section to a bulkier limiting portion. This dimensional transition allows the wire to engage with the thread gap in a way that prevents pull-out, as the enlarged portion cannot pass through the gap once installed.
2Reliability
If a limiting portion with enlarged cross-section is added to the wire, then wire fixation stability is improved, but the device complexity increases
Solution Approach 1:
The limiting portion is integrated directly into the wire structure as a continuous formation with the conductive section, rather than being a separate component. This merging of the limiting portion with the wire itself simplifies the overall device by eliminating the need for separate fixation components, while still providing the necessary structural complexity to prevent pull-out.
Solution Approach 2:
The wire's own limiting portion serves as the fixation mechanism. The enlarged cross-section of the limiting portion naturally engages with the thread gap and accommodating portion to prevent pull-out, without requiring external fixation devices or additional components. The wire essentially fixes itself through its own structural features.
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
Prevents wire dislodgment, thereby enhancing the stability and safety of the lamp socket by ensuring the conductive section is firmly fixed, reducing the risk of safety hazards.
Implementation Method 1
the frictional force between the conductive section and the edge of the accommodating portion is greatly enhanced, and thus it is further ensured that the limiting portion is firmly fixed in the accommodating portion

AI summary
The lamp socket includes a connecting seat, a lamp cap, a first conductive wire and a second conductive wire. The connecting seat has a first passage provided therein, a first threaded section for thread connection with a lamp and an accommodating portion or hole in the first threaded section. The lamp cap is detachably provided at the connecting seat, and has a first conductive region and a second conductive region, the second conductive region having a second threaded section adapted to the first threaded section. A thread gap is formed between the first threaded section and the second threaded section. A limiting portion which may be formed as a mass enlargement at the end of the first wire cooperates with the accommodating portion or hole to prevent pull out of the wire from the thread group.
