Loudspeaker Cabinet Stand for Alignment and Weight Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stage performers face physical strain and safety risks when mounting a heavy upper loudspeaker cabinet above a lower one, as they need to hold the upper cabinet at eye level and align it with a small opening on a mounting pole, which is cumbersome and potentially dangerous.
Innovation Solution
A stand that can be stowed within the lower loudspeaker cabinet and deploys to support the upper cabinet, featuring a recess for a latch, wedges for secure engagement, and a platform with a tapered recess for easy alignment and weight distribution, allowing the upper cabinet to be securely positioned without manual lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a mounting pole with a small opening is used to support the upper loudspeaker cabinet, then the upper cabinet can be positioned at the required height, but the user must manually hold the heavy cabinet at eye level and precisely align it with the small opening, causing physical strain and safety risks
Solution Approach 1:
The mounting system is divided into two independent parts: the stand structure that provides positioning and support, and the loudspeaker cabinet that is placed onto the stand. The stand includes a platform with a recess and alignment features that separate the positioning function from the cabinet, eliminating the need for manual alignment with a small opening.
Solution Approach 2:
The stand platform acts as an intermediary between the mounting pole and the upper loudspeaker cabinet. It provides a large, stable surface with alignment features that facilitate easy placement, mediating the transition from the narrow pole opening to the cabinet bottom opening.
2Strength
If the stand structure is made robust to support the heavy upper cabinet, then the support strength is sufficient, but the stand becomes difficult to maneuver and deploy
Solution Approach 1:
The stand incorporates a movable platform that can be shifted between a stowed position (resting on the lower cabinet) and a deployed position (extended upward for mounting). This dynamic configuration allows the stand to be lightweight and easy to deploy while maintaining structural strength when in the deployed mounting position.
Solution Approach 2:
The stand structure nests within or alongside the lower loudspeaker cabinet when in the stowed position, minimizing space requirements and making the system compact for transport and storage, while deploying outward when needed for mounting.
3Measurement precision
If the stand provides precise alignment features for the upper cabinet, then the alignment is accurate, but the interface structure becomes complex
Solution Approach 1:
Alignment features are concentrated locally at the platform-cabinet interface rather than distributed throughout the entire structure. The recess and alignment protrusions are localized geometric features at the mounting surface, providing precise alignment without requiring complex mechanisms throughout the stand.

AI summary
A stand that is adapted to support an upper loudspeaker cabinet relative to a lower loudspeaker cabinet. The stand has a first structure that is constructed and arranged to be directly coupled to a first portion of the lower loudspeaker cabinet in a stand stowed position wherein the stand is stowed on or in the lower loudspeaker cabinet, and a second structure that is constructed and arranged to be directly coupled to a second portion of the lower loudspeaker cabinet in a stand deployed position wherein the stand is supported by and extends above the lower loudspeaker cabinet. The stand is further constructed and arranged to support the upper loudspeaker cabinet when the stand is in the deployed position.
