Elastic Spacer Training Device for Elbow Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Players in sports like basketball often develop bad habits and poor techniques due to lack of proper training, leading to inconsistent performance, as they lack reminders for maintaining correct arm positioning during shots.
Innovation Solution
A training device with a resilient spacer and adjustable strap system that restricts the elbow bend to 90 degrees, ensuring proper forearm alignment with the upper arm, providing a constant reminder for correct form and allowing forward movement without restriction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a training device restricts arm movement to enforce proper technique, then shooting accuracy and technique consistency improve, but device complexity and ease of operation worsen
Solution Approach 1:
The training device uses a flexible strap that wraps around the forearm and upper arm, employing soft material constraints rather than rigid mechanical structures. This flexible approach enforces the 90-degree arm angle requirement while maintaining simplicity and comfort, resolving the contradiction between reliability improvement and device complexity increase.
2Reliability
If a training device restricts arm movement to enforce proper technique, then shooting accuracy improve, but ease of operation worsen
Solution Approach 1:
The flexible strap design allows the device to be easily adjusted and removed, and does not interfere with natural arm movement when proper technique is used. The soft material constraint is comfortable to wear and does not impede operation, resolving the contradiction between shooting accuracy improvement and ease of operation.
3Stability of the object's composition
If the elbow is restricted to 90 degrees during backward arm movement, then proper shooting form is maintained, but forward arm movement freedom is reduced
Solution Approach 1:
The training device dynamically adapts to different phases of the shooting motion. During backward arm movement (pre-shot preparation), the flexible strap actively restricts the elbow to maintain 90-degree positioning. During forward arm movement (shot execution), the strap becomes passive and does not interfere with natural arm extension, thus maintaining positioning consistency when needed while preserving movement freedom when not needed.
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
The device helps develop neuromuscular memory by ensuring consistent arm positioning, improving shooting technique and increasing the percentage of successful shots by maintaining proper form and muscle development.
Implementation Method 1
The device includes a resilient spacer means such as a block or ball disposed within a pocket in a strap

AI summary
A training device for limiting limb movement over a predetermined range of motion providing habit formation for activities such as sports requiring memory of arm or leg movement. The device includes a resilient spacer means such as a block or ball disposed within a pocket in a strap which fits snugly around the players forearm. The spacer means and pocket are oriented in a position to permit limited pivotal movement of the elbow to an angle of about 90 degrees whereby the spacer contacts the forearm and upper arm. The elbow is prevented from pivoting beyond the point at which the forearm forms a selected angle with the upper arm. The strap is adjusted by a user to restrict the angle to which the elbow can be bent on the backward movement of the arm. Forward movement of the arm during a shot is not restricted.
