Dual-Use Speaker Stand Adaptor for Variable Mounting Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker stands require multiple designs or replaceable parts to accommodate speakers of different sizes or brands, leading to inconvenience in transportation and manpower burden.
Innovation Solution
A dual-use adaptor with a stationary tube, conversion nut, adjusting stud, and positioning screws that allow for adjustable insertion into various speaker holes by rotating the conversion nut to extend or retract the adjusting stud, accommodating different speaker sizes and brands with a single adaptor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple speaker stands with different connecting poles are used to accommodate speakers of different sizes or brands, then the adaptability to different speakers is improved, but the device complexity and transportation burden increase
Solution Approach 1:
The patent applies universality by designing a single speaker stand with a convertible connecting pole that can serve multiple functions. The connecting pole can be transformed between a first state (protruding for inserting into speaker holes) and a second state (retracted or positioned differently for alternative connection methods). This allows one speaker stand to accommodate different speaker sizes and brands, eliminating the need for multiple specialized stands while maintaining adaptability.
2Adaptability or versatility
If multiple replaceable connecting poles are provided for different speaker connection holes, then the adaptability to different speaker hole sizes is improved, but the ease of operation and transportation convenience deteriorate
Solution Approach 1:
The patent applies dynamics by making the connecting pole convertible rather than static. The connecting pole can dynamically change its configuration between a first state and a second state through conversion mechanisms (such as telescopic sections, rotating joints, or adjustable components). This dynamic capability allows the same pole to adapt to different connection hole sizes and types without requiring multiple separate poles, thereby improving ease of operation and transportation while maintaining compatibility with various speakers.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a single adaptor to fit multiple speaker sizes and brands, reducing the need for multiple stands and simplifying transportation and setup.
Implementation Method 1
The conversion nut rotationally couples with a second end of the stationary tube. The adjusting stud is disposed within the stationary tube to threadably couple with the conversion nut and comprises a positioning groove. Whereby rotation of the conversion nut causes the adjustment stud to move axially along the stationary tube

AI summary
A dual-use adaptor includes a stationary tube, a section tube, a conversion nut, an adjusting stud, a first positioning screw, and a second positioning screw. The stationary tube includes a first end fixed to the section tube and a second end rotationally coupled to the conversion nut. The adjusting stud includes a positioning groove and is disposed within the stationary tube to threadably couple with the conversion nut. The first positioning screw extends radially from the inner wall of the stationary tube to the conversion nut. The second positioning screw extends radially from the inner wall of the stationary tube to the positioning groove. Rotation of the conversion nut causes the adjustment stud to move axially along the stationary tube.
