Loudspeaker Accessory Tray with Rake Angle for Stable Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Loudspeakers often lack a secure and convenient method to support accessories like wireless receivers, which can lead to instability and difficulty in vertical stacking due to their inherent design, especially when the top side is angled.
Innovation Solution
An accessory tray with a main portion and an anchor portion that securely attaches to the loudspeaker, featuring a rake angle to accommodate the loudspeaker's orientation and a strap to hold accessories in place, allowing for vertical stacking and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If accessories are placed on the top side of a loudspeaker, then they can be easily accessible, but they become unstable when the loudspeaker is tilted
Solution Approach 1:
The accessory tray utilizes the angled top surface of the loudspeaker (which tilts backward) as a functional feature rather than a flaw. By designing the tray with a complementary rake angle that matches the loudspeaker's tilt, the tray maintains a horizontal base surface that provides stability for accessories while leveraging the angled orientation for secure attachment to the tilted top surface.
2Shape
If the loudspeaker top side is angled for design purposes, then it has aesthetic appeal and proper sound projection, but it prevents stable accessory placement and vertical stacking
Solution Approach 1:
The accessory tray is designed with differentiated zones: the contact surfaces at the rear have a rake angle that matches the loudspeaker's tilt for secure engagement, while the base surface remains horizontal to provide a stable platform for accessories. This local differentiation of angular properties allows the tray to simultaneously adapt to the angled loudspeaker surface and provide stability for accessories.
Solution Approach 2:
The tray transforms the problematic angled surface into a useful attachment interface by matching its rear contact surfaces to the loudspeaker's rake angle, while maintaining a horizontal base surface dimension that enables stable accessory placement and vertical stacking capability.
3Device complexity
If accessories are simply placed on the loudspeaker without a tray, then the structure remains simple, but accessories can slide off when the loudspeaker is tilted
Solution Approach 1:
The tray's horizontal base surface creates a new stable dimension for accessory placement that counteracts the tilt of the loudspeaker. By introducing this intermediate horizontal platform, the tray prevents accessories from sliding off while maintaining overall structural simplicity through its compact, integrated design.

AI summary
An accessory tray for a loudspeaker includes a main portion defining a perimeter and a base surface configured to support an accessory within the perimeter. An anchor portion extends under the base surface of the main portion, the anchor portion configured to engage a portion of the loudspeaker. The main portion has a tapering height from a rear to a front thereof, forming a rake angle in side view.
