Adjustable Control Stick Assembly With Rotational Height Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video game controllers have fixed control stick heights, requiring users to dismantle the controller and replace control sticks to adjust the height, which is cumbersome and inefficient.
Innovation Solution
An adjustable control stick assembly that allows users to rotate the control stick handle to raise or lower the control stick without removing it from the controller, using a protrusion and indents mechanism to change the height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the control stick height is fixed during manufacture, then the manufacturing process is simple, but the controller cannot be adapted to different game requirements
Solution Approach 1:
The control stick assembly transitions from a fixed height design to a dynamic, adjustable height design. The shaft can rotate relative to the shell, allowing the control stick to extend to different heights based on user needs while maintaining a relatively simple overall structure.
Solution Approach 2:
The control stick shaft is nested within the shell, with the shaft rotating inside the shell's cavity. The protrusion on the shaft engages with indents in the shell, creating a compact nested structure that allows height adjustment without adding external complexity.
2Adaptability or versatility
If multiple control sticks of different heights are provided, then different game requirements can be met, but the user must physically dismantle the controller to replace control sticks
Solution Approach 1:
Instead of requiring physical replacement of control sticks, the design allows dynamic adjustment where the single control stick shaft can rotate to different positions, effectively providing multiple heights without dismantling the controller.
Solution Approach 2:
A single control stick assembly serves multiple functions by providing adjustable heights. The same shaft and shell combination can accommodate different control stick heights, eliminating the need for multiple separate control stick components.
3Ease of operation
If the control stick shaft is rotatably positioned in the shell with protrusion and indents, then the control stick height can be adjusted by rotation, but the structural complexity increases
Solution Approach 1:
The control stick assembly is segmented into distinct functional elements: the shaft with protrusion, the shell with indents, and the notched engagement mechanism. This segmentation allows each component to be simple in itself while combining to provide adjustable functionality.
Solution Approach 2:
The protrusion and indent mechanism acts as an intermediary that enables height adjustment. The protrusion on the shaft engages with corresponding indents in the shell, providing a simple mechanical interface that translates rotation into discrete height positions without complex mechanisms.

AI summary
A video game system controller control stick includes a control stick shaft and a control stick shell. The control stick shaft is rotatably positioned in a notch of the control stick shell and an end of the control stick shaft extends above the control stick shell. The control stick shaft includes a protrusion and the control stick shell includes a plurality of indents engageable by the protrusion to position the end of the control stick shaft at different heights with respect to the control stick shell. A first indent and a second indent are positioned such that rotation of the control stick shaft when the protrusion engages the first indent causes the protrusion to move into engagement with the second indent.
