DJ Controller Deck Segmentation for Multi-Channel Beat Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-deck/four-channel DJ controllers lack intuition and instantaneous operability when performing four-deck operations, leading to stress and incorrect operations due to the need for frequent deck switching and confusion about which deck is active.
Innovation Solution
An operation device with a load operation member and a play operation member for each channel allows for loading and reproducing signals on multiple channels without switching decks, incorporating features like fader start function, cue select, and beat synchronization to enhance operability and originality in music composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a two-deck/four-channel layout is used in an integral type controller, then the main frame size is reduced, but the DJ cannot operate decks on reverse side simultaneously with front side decks, leading to lack of intuition and instantaneousness
Solution Approach 1:
The controller is divided into front side decks and reverse side decks as separate operable units. Each deck can be independently operated, and the reverse side decks are accessible without interfering with front side deck operations. This segmentation allows simultaneous operation of multiple decks while maintaining intuitive control for each side.
Solution Approach 2:
The controller utilizes a three-dimensional layout by placing decks on both the front side and reverse side of the main frame. This spatial arrangement in multiple dimensions allows DJs to access and operate reverse side decks without switching away from front side decks, enabling simultaneous multi-deck operations while keeping the main frame compact.
2Adaptability or versatility
If deck switching operation is required to operate reverse side decks, then the number of decks that can be operated simultaneously is limited, but this increases the complexity of operations and reduces simultaneous operability
Solution Approach 1:
The controller separates front side decks and reverse side decks into independent operational segments. Each segment can be operated simultaneously without requiring switching between them. This segmentation enables DJs to load and play tracks on reverse side decks while continuing to perform operations on front side decks, increasing simultaneous operability without adding operational complexity.
3Productivity
If frequent deck switching is required, then the number of channels that can be mixed is maintained, but the DJ may operate incorrectly due to confusion about which deck is currently assigned
Solution Approach 1:
The controller divides the four channels into front side decks (channels 1-2) and reverse side decks (channels 3-4), with each deck permanently assigned to specific channels. This segmentation eliminates confusion about deck assignments because DJs know exactly which deck controls which channel without needing to switch or remember dynamic assignments. Each deck maintains its channel assignment throughout operation, ensuring accuracy while enabling multi-channel mixing capability.

AI summary
The DJ controller 10 has a load operation member 82 that loads audio signals to each channel, a synchronization button 84 that realizes a beat synchronization function, and a channel fader 85 that reproduces the loaded audio signals by the fader start function corresponding to each channel.
