Solution Overview

Problem

Existing water walking devices are cumbersome, lack stability, and do not provide a convenient means for users to sit and rest while on the water, with issues such as foot entrapment and limited mobility.

Innovation Solution

The design incorporates inflatable pontoons with integrated footwells that allow easy entry and exit, a platform for sitting and resting, and a ladder for safe reboarding, along with a narrow support board for stability and scoops that prevent backward movement, all of which enhance user experience and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If foot is attached to the top of the pontoon with a foot piece, then the user can walk on water, but the device becomes cumbersome and the foot may get caught inside the footwell

Engineering Contradiction:
Improveease of foot entry and exitVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pontoon is divided into functional segments: an inflatable buoyant section and a rigid footwell section. The footwell is separated from the main pontoon body by a bulkhead, allowing independent design optimization. This segmentation enables the footwell to be structured for easy foot entry/exit while the inflatable pontoon provides buoyancy, resolving the contradiction between ease of operation and device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The footwell is nested within or attached to the inflatable pontoon structure. The rigid footwell acts as a nested component within the larger inflatable pontoon system, allowing the footwell to provide structural integrity and easy foot access while being supported by the inflatable buoyant structure, thus reducing overall device complexity while maintaining ease of operation.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If no platform is attached to the pontoons, then the device is simpler, but the user cannot sit and rest while on the water

Engineering Contradiction:
Improveability to sit and restVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The platform serves multiple functions: it provides a resting surface for the user to sit during water walking, acts as a stable base for mounting additional equipment (fishing rods, storage containers), and extends the usable area of the device. This multi-functionality increases adaptability without proportionally increasing complexity, as the platform is a simple structural addition that fulfills multiple user needs.

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

3Ease of operation

If the footwell is small, then the pontoon structure is simpler, but the user's foot may get caught inside the footwell

Engineering Contradiction:
Improveease of foot entry and exitVSAvoidfootwell structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The footwell is designed with specific local qualities: a wide opening at the top for easy foot access, a bulkhead at the rear to prevent foot entrapment, and appropriate depth to accommodate the foot without being too large. These localized structural features address the foot entrapment problem without requiring complex overall footwell structure, maintaining simplicity while ensuring ease of operation.

Inventive Principle:
Principle #3Local quality

4Ease of operation

If the pontoons lack stability, then the device is lighter and easier to inflate, but the user experiences difficulty and fatigue while walking on water

Engineering Contradiction:
Improvestability while walkingVSAvoidpontoon weight
Core Design Contradiction:
Ease of operationVSWeight of stationary object

Solution Approach 1:

The pontoon system uses composite construction: inflatable vinyl or plastic material for buoyancy combined with rigid components (footwells made from PVC pipe, aluminum extrusions, or other rigid materials). This composite approach provides enhanced stability and structural integrity without excessive weight, as the inflatable portions remain lightweight while the rigid elements provide necessary stability for comfortable water walking.

Inventive Principle:
Principle #40Composite materials

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 solution provides greater stability, ease of use, and extended periods of water-based activity, allowing users to walk, sit, and paddle without obstruction, while ensuring safe entry and exit from the water.

Implementation Method 1

The present invention employs a number of new approaches for solving the problems that exist in water walking devices. Rather than having the foot held into the footwells, or attached to the top of the pontoons

Methodology Applied
Scientific EffectBuoyancy: Archimedes' Principle (Buoyancy)

Implementation Method 2

It is also an advantage that a narrow support board at the bottom of the pontoon gives the pontoon its rigidity, and acts as a keel for the pontoon. This gives the user greater stability and easier handling of the apparatus when walking on the water.

AI summary

A water walking apparatus having two inflatable pontoons, each with respective holes in their top surfaces for a footwell. A platform support may expand and contract when in use so as to accommodate variable spacing between the pontoons. The platform support may include curved saddle, which straddles over the curved outer surface of a pontoon, securing the platform support to the pontoons. A platform upon which a user may sit may be connected to the platform support by a neck received into a hole in the bottom of the platform. The platform may include a backrest member, and a strap that may serve as a ladder step when the backrest member is rotated rearwardly and down, into the water to allow a user to step on the continuous strap and climb up onto the platform.
