Adjustable Sports Goal with Rear Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports goals that are adjustable in size often fail to meet the requirements of sports administrative bodies due to structural issues that affect the bounce of a football, and they require multiple goals of varying sizes for different training sessions, leading to storage and logistical challenges.
Innovation Solution
A sports goal with a self-supporting structure featuring telescopic elements and locking mechanisms that allow for adjustable dimensions, with locking members positioned on the rear face to avoid interfering with ball rebounds, and a rolling ballast for stability, enabling easy movement and storage while meeting competition standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustable goals with telescopic elements are used, then the goal can be modified to different sizes, but the structure cannot be approved by sports administrative bodies due to ball bounce issues
Solution Approach 1:
The locking means are extracted from the front face and positioned on the rear face of the telescopic elements. This removes the problematic locking mechanism from the ball's path, eliminating the interference with ball bounce while preserving the size adjustment capability. The locking means still secure the telescopic elements but do so from a location that does not affect ball behavior.
2Adaptability or versatility
If multiple goals of varying sizes are purchased for different training sessions, then different training needs are met, but storage and logistical challenges increase
Solution Approach 1:
The goal structure is designed with telescopic elements that allow a single goal to serve multiple functions by adjusting to different sizes. This universal design enables one goal to replace multiple fixed-size goals, meeting various training needs while eliminating the storage and logistics issues associated with managing multiple separate goals.
3Stability of the object's composition
If locking means are positioned on the front face, then the telescopic elements are secured, but the locking means interfere with ball rebounds
Solution Approach 1:
The locking means are extracted from the front face and repositioned on the rear face of the telescopic elements. This spatial relocation maintains the stabilizing function of securing the telescopic elements while removing the harmful interference with ball rebounds that occurred when the locking means were on the front face.
