Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electro-acoustic microphone boom stands face challenges with stability, portability, and secure counterweight attachment, leading to potential tipping, sagging, and acoustic vibrations, due to inadequate coupling and counterweight designs in prior art.
Innovation Solution
A boom stand with a stacking counterweight system featuring cylindrical weights with large grasping surfaces and threaded couplers, allowing for easy manual attachment and detachment, providing customizable counterbalance without tools and minimizing vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a large and massive base is used to provide stability during movement and adjustment of the boom, then stability is improved, but portability and ease of transport deteriorate
Solution Approach 1:
The counterweight is divided into multiple detachable segments that can be individually attached or removed from the boom. This allows the user to configure the total counterweight mass according to specific needs, providing stability when required while maintaining portability when segments are removed or the stand is disassembled for transport.
2Stability of the object's composition
If a large and massive base is used to provide stability, then stability is improved, but ease of storage and compact arrangement deteriorates
Solution Approach 1:
The counterweight system is segmented into detachable components that can be removed from the boom. When segments are removed, the boom and stand occupy less space, enabling compact storage and tight arrangement of multiple stands without sacrificing the ability to provide stability when segments are attached during use.
3Stability of the object's composition
If tripod legs are made longer to provide stability against tipping, then stability is improved, but safety deteriorates due to hazard to passing persons
Solution Approach 1:
Instead of extending leg length to achieve stability, the invention uses counterweights attached to the boom to provide the necessary stabilizing moment. This allows the legs to remain at a safe, shorter length while still preventing tipping through the counterbalancing effect of the weights positioned on the boom.
4Reliability
If counterweights are securely attached to prevent sagging and vibration, then reliability is improved, but ease of operation deteriorates due to difficulty in attachment and adjustment
Solution Approach 1:
The counterweight system uses segmented, detachable components with threaded couplers that enable secure attachment to prevent sagging and vibration. The segmented design with standardized threading allows reliable, tool-free attachment and adjustment while maintaining ease of operation through simple screw-on/screw-off mechanisms.
5Reliability
If counterweights are made with threaded couplers for secure attachment, then reliability is improved, but device complexity increases
Solution Approach 1:
The threaded coupler design serves multiple functions: it provides secure attachment to prevent sagging, enables easy detachment for portability, allows for adjustment of counterweight position, and facilitates tool-free operation. This universal mechanism reduces overall device complexity by consolidating multiple requirements into a single simple threading interface.

AI summary
A boom stand adapted to support an electroacoustic device is constructed from a base, pivotal boom, stand elevating the pivotal boom, and a stacking counterweight. The stacking counterweight includes a terminal weight having a generally cylindrical body longitudinally terminated with a threaded coupler adapted to operatively couple with a threaded coupler on the boom, while aligning the terminal weight longitudinally co-axially with the boom. One or more medial weights having a generally cylindrical body and appropriate threaded couplers can be inserted between the boom and terminal weight. Each of the medial and terminal weights are preferably shaped to be adequately grasped by a person's palm and finger portion of a hand clasping about the longitudinal axis, and are thereby adapted to operatively permit manual rotation about their longitudinal axes.
