Solution Overview

Problem

Existing submersible stern platforms on vessels lack a recreation device that is concealable in a sliding manner, with backrest elements and a removable cover for positioning the feet, requiring complex assembly and movement systems.

Innovation Solution

A submersible stern platform with a recess that houses a recreation device, which slides between closed and open positions, featuring movable backrest elements and a removable cover for foot positioning, using manual or motorized traction systems for movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a recreation device is added to the submersible stern platform, then the functionality and leisure capabilities are improved, but the device complexity and assembly effort increase

Engineering Contradiction:
Improverecreation functionalityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The recreation device is nested within a recess of the platform, allowing it to be concealed when not in use and integrated into the platform structure, thereby adding functionality without permanently increasing device complexity or requiring separate assembly processes

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If the recreation device is made concealable in a sliding manner, then the ease of operation and concealment are improved, but the device complexity increases

Engineering Contradiction:
Improveconcealment easeVSAvoidmovement system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The recreation device is designed to slide between concealed and visible positions along rails, allowing dynamic adaptation to different usage scenarios. This sliding mechanism provides ease of operation while maintaining relatively simple construction through the use of straightforward rail-guided movement

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If backrest elements and foot positioning cover are added, then the comfort and usability are improved, but the device complexity and number of parts increase

Engineering Contradiction:
ImproveusabilityVSAvoidnumber of parts
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The backrest elements and foot positioning cover are integrated as part of the recreation device structure. The cover that positions the feet also serves as a structural element, and the backrest elements are incorporated into the same sliding assembly, thereby improving comfort without proportionally increasing the number of separate parts

Inventive Principle:
Principle #5Merging (Combining)
