Track Adapter Phase Switching With Hidden Rotating Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional track adapters have an unattractive appearance and increased cost due to the exposed phase adjustment mechanism, making it difficult to achieve flexible phase adjustment and aesthetically pleasing designs in track lighting systems.
Innovation Solution
The track adapter incorporates a positive conductive connection with a first rotating conductive structure and a negative conductive connection with a second rotating conductive structure, featuring annular conductive sheets, elastic members, and U-connector designs to maintain constant conduction and facilitate phase adjustment, while being integrated with a drive power supply and lamp holder for a clean and flexible design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the phase adjustment mechanism is placed at the bottom of the adapter, then the phase adjustment function is achieved, but the appearance becomes unattractive and cost increases
Solution Approach 1:
The patent inverts the conventional design by moving the phase adjustment mechanism from the bottom of the adapter to the top. The adjustment knob is now located on the top surface, making it aesthetically pleasing while maintaining full phase adjustment functionality. This inversion resolves the contradiction between operational function and appearance.
2Adaptability or versatility
If multiple conductive metal sheets and phase regulators are set up, then different power supply modes are achieved, but device complexity increases
Solution Approach 1:
The adapter employs a universal design where a single phase regulator can control multiple conductive metal sheets through the rotatable adjustment mechanism. The phase regulator serves multiple functions by being able to connect to different conductive sheets at different rotation positions, reducing the need for separate components for each power supply mode and thereby simplifying the overall device complexity.
3Adaptability or versatility
If the adjustment conductive part is rotatably provided with multiple positive contacts, then phase adjustment flexibility is improved, but manufacturing complexity increases
Solution Approach 1:
The patent implements a nested structure where the adjustment conductive part with multiple positive contacts is integrated within the adapter body. The rotatable mechanism is nested inside the housing, with the conductive contacts arranged in a compact circular pattern. This nesting approach maintains phase adjustment flexibility while simplifying manufacturing by reducing the number of separate components and assembly steps.
