Water Jug Exercise Device with Cutouts and Attachment Hole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard water jugs/cans interfere with wrist and elbow movement during exercises like bicep and butterfly curls due to their shape, causing discomfort, and lack compatibility with bench press or curling bars for increased weight distribution.
Innovation Solution
Designing a water jug/can with half-moon cutouts and a hole near the top to accommodate wrist and forearm movement and allow attachment of standard curling or bench press bars, enabling full-range curls and safe weight distribution for various exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard water jug/can is used for exercise, then it provides a simple and accessible weight, but the shape interferes with wrist and elbow movement causing discomfort and preventing full range of motion
Solution Approach 1:
The jug is segmented by creating half-moon cutouts in its body, dividing the solid structure into a modified form with strategic openings. This segmentation allows the wrist and forearm to pass through or alongside the jug during curls, eliminating the interference caused by the solid cylindrical shape while maintaining the jug's weight-bearing function
Solution Approach 2:
Material is extracted from the jug's body by removing sections to create half-moon cutouts. This extraction creates negative space that accommodates the user's anatomy during exercise, specifically allowing the wrist and forearm to move freely without contacting the jug's surface, thus resolving the discomfort issue
2Adaptability or versatility
If a standard water jug/can is used, then it is simple in design, but it cannot safely attach to bench press or curling bars for increased weight distribution
Solution Approach 1:
The jug is designed with a standardized hole near the top that serves multiple functions: it allows the jug to be attached to curling bars for bench press exercises, enables secure handling during curls, and maintains compatibility with standard gym equipment. This universal attachment point transforms the jug from a single-purpose weight into a multi-functional exercise tool
Solution Approach 2:
The hole in the jug is positioned and sized to accommodate standard curling bar attachments, allowing the bar's attachment mechanism to nest within or around the jug's opening. This nesting arrangement enables secure mechanical connection between the jug and exercise equipment without requiring complex modification of either component
3Ease of operation
If a water jug with half-moon cutouts and attachment hole is designed, then it enables full-range comfortable movement and equipment compatibility, but the manufacturing process becomes more complex
Solution Approach 1:
The half-moon cutouts are designed with curved, ergonomic contours that follow the natural shape of the wrist and forearm. These curved openings are easier to manufacture using standard plastic injection molding techniques or rotational molding processes, as they maintain the jug's overall rounded form while creating the necessary anatomical clearances

AI summary
An exercise device includes a jug including a first external cutout portion and a second external cutout portion together forming an external cutout having a cross shape in the outer surface of the jug. The jug also includes a first, second, and third handle. The exercise device is configured to allow a user's wrist and forearm to enter the cutout portions.
