Rotationally Adjustable Lamp Shell Guiding Slot Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing methods for rotationally adjustable lamps are not cost-effective and simple, often requiring complex processes that can lead to electrical disconnection during adjustment.
Innovation Solution
A method involving molding a shell with guiding slots and a base with notches that protrude into these slots, allowing the shell to be rotated relative to the base without disconnecting from the electrical power source, using conventional tools and techniques, and incorporating multiple guiding slots for enhanced adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional manufacturing methods are used for rotationally adjustable lamps, then the lamp can be manufactured, but the manufacturing process becomes complex and costly
Solution Approach 1:
The lamp is divided into distinct modular components: a base with electrical connection and a shell with guiding slots. This segmentation allows each part to be manufactured separately using simple processes, then assembled together to achieve rotational adjustability without complex integrated manufacturing
Solution Approach 2:
The guiding slots are pre-formed in the shell during molding, and the base is prepared with corresponding features before assembly. This preliminary preparation of components enables the rotational adjustment mechanism to be achieved through simple assembly operations rather than complex post-manufacturing processes
2Ease of operation
If the lamp is designed for rotational adjustment, then optimal illumination can be achieved, but electrical disconnection may occur during adjustment
Solution Approach 1:
A contactless electrical connection mechanism is introduced as an intermediary between the base and shell. This allows the shell to rotate freely within the guiding slots while maintaining continuous electrical power supply without physical contact that could disconnect during adjustment
Solution Approach 2:
The electrical connection system is designed to be dynamic rather than rigid, allowing it to accommodate the rotational movement of the shell. The connection maintains reliability throughout the range of motion enabled by the guiding slots, ensuring continuous power supply during adjustment operations
3Measurement precision
If precise rotational positioning is enabled, then optimal illumination is achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The guiding slots are designed with curved geometries that naturally guide the shell to specific rotational positions. The curved paths provide precise positioning through geometric constraints rather than requiring complex mechanical positioning mechanisms or multiple adjustment components

AI summary
A method for manufacturing a rotationally adjustable lamp (1) is disclosed. The method comprises: molding a shell (6) having a guiding slot (7a); providing a base (2) configured to receive the shell (6) and connect to a lamp socket; inserting the shell (6) into the base (2) so as to enclose the guiding slot (7a) by the base (2); and forming in the base (2), when the shell (6) is inserted into the base (2), a notch (5) protruding into the guiding slot (7a), the notch (5) being movable along the guiding slot (7a) so as to allow for the shell (6) to be rotated relative to the base (2).
