Solution Overview

Problem

Existing weight belts for free divers are cumbersome to remove quickly and adjust accessories, posing safety risks and wasting time, especially when divers need to change activities underwater.

Innovation Solution

A weight belt with a buckle and knob-back screw fasteners that allow for quick attachment and detachment of accessories, enabling divers to customize their gear during a dive without removing weights, using a belt material that can be punched for secure fastening and a 270-degree loop for accessory holders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional weight belts are used with knots or bands, then the belt can be removed, but it requires both hands and takes too long, which is dangerous when the diver needs to surface quickly

Engineering Contradiction:
Improvespeed of weight belt removalVSAvoidsafety of quick removal
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The weight belt is divided into a belt body and detachable weight pouches connected by quick-release buckles. This segmentation allows the diver to quickly detach only the weights without having to undo the entire belt, enabling one-handed operation and rapid weight removal for emergency surfacing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The quick-release buckle mechanism transforms the static, fixed connection of traditional knotted belts into a dynamic, easily changeable connection. The buckle can be rapidly opened with one hand, allowing the diver to adjust or remove weights quickly in response to changing dive conditions or emergencies.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If accessories are attached to the weight belt, then the diver has all needed gear, but modifying weights and accessories requires removing them from the belt, which wastes time and cannot be safely done while in water

Engineering Contradiction:
Improveability to modify accessoriesVSAvoidtime to change accessories
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The weight belt is designed with multiple attachment points and a standardized quick-release buckle system that can accommodate various accessories beyond just weights, such as cameras, lights, and tools. This universal attachment system allows the diver to quickly swap between different accessory configurations without removing items from the belt, enabling on-the-fly modifications while diving.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the diver carries all necessary accessories on the weight belt, then the diver is prepared for various activities, but the belt becomes cumbersome and difficult to manage

Engineering Contradiction:
Improvevariety of accessoriesVSAvoidbelt management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The belt system is segmented into modular components with dedicated attachment points for different accessory types. This organization allows the diver to distribute accessories along the belt length and access them independently, reducing tangling and making the system easier to manage despite carrying multiple items.

Inventive Principle:
Principle #1Segmentation
