Bracket Assembly for Pistol Drill Positioning in Hoop Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing basketball hoop systems require significant hand strength and physical effort to raise and lower the hoop, as they lack an efficient mechanism for rotating the screw mechanism.
Innovation Solution
A bracket assembly is hingedly attached to the elevation post of a basketball hoop system, featuring a base plate with opposing arms and an aperture for a bit engagement with a drill adapter, allowing a pistol drill to turn the screw for raising and lowering the hoop while preventing rotational movement of the drill, thus reducing operator effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual screw mechanism is used to raise and lower the hoop, then the hoop can be adjusted in height, but significant hand strength and physical effort are required to operate it
Solution Approach 1:
A bracket assembly with opposing arms acts as an intermediary mechanism between the pistol drill and the screw. The bracket receives rotational force from the pistol drill and transfers it to the screw mechanism, providing mechanical advantage that reduces the hand strength required to operate the hoop adjustment.
Solution Approach 2:
The system uses a standard pistol drill as a self-service power source. The pistol drill, which is already a common tool with sufficient rotational force, is adapted to drive the screw mechanism, eliminating the need for specialized manual cranking mechanisms and reducing the operational effort required.
2Ease of operation
If a pistol drill is used to turn the screw mechanism, then operational effort is reduced, but the drill may rotate uncontrollably without proper constraints
Solution Approach 1:
The bracket assembly provides localized constraints at specific points along the pistol drill shaft. The opposing arms engage with the drill at strategic locations to prevent rotational movement in unwanted directions while allowing the necessary rotational force to be transmitted to the screw mechanism.
Solution Approach 2:
The bracket assembly is pre-positioned and configured before operation begins. It establishes the proper geometric constraints and alignment between the pistol drill and screw mechanism in advance, ensuring stable force transmission and preventing uncontrollable drill rotation during operation.

AI summary
A hinged bracket assembly with a base plate having two L-shaped extended opposite arms and an aperture aligned with a bit in a basketball elevation post, where the bit is engaged with a gear operably engaged to a screw in the elevation post, wherein the opposite arms are sized to provide lateral blocking to the rotation of a pistol drill engaged to an adapter that mates to the bit wherein the drill is capable of turning the adapter to raise and lower the basketball hoop by turning the bit. The arms are made of metal or other rigid material and integrally hinged with the base plate to permit upward and downward movement. The bracket assembly may have magnetic engagement to the elevation post when not in use. The arms may form a pin within a sleeve on the base plate.
