Modular Workout Mace With Secure Variable Weight Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Workout maces lack customizability and portability due to fixed weights, leading to space inefficiency and safety risks, and existing adjustable solutions are impractical or unsafe for maces.
Innovation Solution
A modular workout mace system with variable weights using threaded connections, elastic stoppers, and spring plungers for secure, quick coupling, along with a multi-section handle for adjustable length and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a unibody design is used for workout maces, then the structure is simple and reliable, but customizability and portability are poor
Solution Approach 1:
The workout mace is divided into multiple independent sections: a handle section, a mace head section, and multiple detachable weight sections. Each section can be independently selected and combined through threaded connections, allowing users to customize the total weight and configuration. This segmentation enables a single mace device to replace multiple fixed-weight maces, achieving adaptability without requiring complex internal mechanisms within each component.
2Adaptability or versatility
If multiple fixed-weight maces are purchased to achieve full set of weights, then weight options are complete, but storage space and cost increase
Solution Approach 1:
Multiple weight sections are designed to be compatible with a single handle and mace head assembly. Users can combine different weight sections (e.g., 5lb, 10lb, 15lb sections) on one mace device to achieve various total weights (5lb, 10lb, 15lb, 20lb, etc.). This merging approach allows a single physical mace device to function as multiple fixed-weight maces, dramatically reducing storage space requirements from storing 7 separate maces to storing one modular device with interchangeable weight components.
3Ease of operation
If collar clamp is used to hold weights on mace, then weight adjustment is possible, but reliability is poor and weight dropping risk exists
Solution Approach 1:
The unreliable collar clamp mechanical system is replaced with a threaded connection system. The mace head and weight sections feature integrated threaded interfaces that require screwing or unscrewing for attachment or detachment. This threaded mechanical engagement provides significantly higher reliability than collar clamps, as the threads create interlocking engagement that resists loosening under dynamic loads, while still allowing easy weight adjustment when needed. The threaded system eliminates the slipping and malfunction issues inherent in collar clamp designs.
4Reliability
If spring and socket thread lock solution is used for handle, then thread locking is achieved, but handle weight increases and portability decreases
Solution Approach 1:
The heavy spring and socket thread locking mechanism is extracted and removed from the handle design. Instead, a simpler threaded connection interface is used at the handle-mace head junction, relying on the friction and mechanical engagement of the threads themselves without requiring additional locking components. This extraction of the heavy locking mechanism maintains adequate thread locking reliability for the application while dramatically reducing handle weight, thereby improving portability and making the mace easier to carry and maneuver.
