Telescoping Batting Tee Mechanism for Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional batting tees are often large and unwieldy, making them difficult to transport and adjust to accommodate batters of varying heights and swing styles.
Innovation Solution
A telescoping mechanism comprising concentric rods with O-rings and collars allows the batting tee to collapse and extend, providing adjustable height and improved portability, featuring a base, attachment portion, and a ball holder that can be easily assembled and disassembled for different user needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the batting tee is made height adjustable to accommodate various batters, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent implements a telescoping mechanism where the second rod is positioned at least partially within the first rod, allowing the batting tee to adjust height by extending or retracting the inner rod within the outer rod. This nesting approach provides continuous height adjustment without requiring multiple discrete components or complex assembly mechanisms.
2Ease of operation
If the batting tee is made portable, then the ease of operation is improved, but the length of the object increases when extended
Solution Approach 1:
The telescoping rods allow the batting tee to collapse into a compact form for transport by nesting the second rod within the first rod, significantly reducing the overall length and improving portability while maintaining full extended length when needed for use.
Solution Approach 2:
The batting tee transitions between static and dynamic states, collapsing to a compact form for transport and extending to full height for use. The telescoping mechanism enables this dynamic transformation, allowing the device to adapt its dimensions based on operational requirements.
3Reliability
If the telescoping mechanism uses O-rings and collars for stability, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The telescoping rods are equipped with O-rings and collars that provide friction-based locking mechanisms. These simple passive components maintain the telescoped position through friction alone, ensuring stable height adjustment without requiring active locking mechanisms, motors, or complex fastening systems.
Solution Approach 2:
The O-rings and collars on the telescoping rods provide self-locking through friction, automatically maintaining the desired height position without requiring external locking mechanisms or active control systems. The friction between the O-rings and rod surfaces self-regulates to hold the telescoped position.

AI summary
A batting tee includes a base and an attachment portion attached to the base. A first rod is optionally releasably connected to the attachment portion. A second rod having an outer diameter less than an inner diameter of the first rod is positioned at least partially in the first rod. One or more O-rings are positioned on the second rod within the first rod. A collar is attached to the first rod and positioned to allow the second rod to pass through the collar while resisting passage of the O-ring out of the first rod. A rod cap is attached to an end of the second rod and positioned to resist removal of the O-ring from the second rod. A ball holder is attached to the other end of the second rod. The second rod is movable telescopically within the first rod to raise and lower the ball holder.
