Solution Overview

Problem

Existing inflatable seating in spas does not allow users to adjust the seating to their desired height or comfort level, and there is a lack of adjustable built-in seating options.

Innovation Solution

A spa with built-in seating that includes an inflatable bench and backrest attached by adjustable attachment assemblies, allowing users to adjust the position and orientation of the backrest relative to the bench, and optionally featuring multiple attachment points for enhanced adjustability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If inflatable seating is integrally formed to the air chamber, then the structure is simplified and easier to manufacture, but users cannot adjust the seating to their desired height or comfort level

Engineering Contradiction:
Improveseating structure integrationVSAvoidseating adjustability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The seating assembly is divided into separate components: an inflatable bench portion and a separate backrest portion. This segmentation allows each component to be independently adjusted and positioned, enabling users to customize the seating configuration while maintaining manufacturing simplicity through modular construction

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The attachment assemblies connecting the backrest to the bench are designed to be adjustable in length, transforming the seating from a fixed configuration to a dynamic, user-adjustable system. This allows the backrest position and angle to be modified according to user comfort requirements

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If fixed attachment assemblies are used to connect the backrest to the bench, then the structure is more stable, but users cannot adjust the position of the backrest

Engineering Contradiction:
Improveseating structure stabilityVSAvoidbackrest position adjustment
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The attachment assemblies incorporate adjustable length mechanisms that allow the connection between the backrest and bench to be modified. This dynamic adjustment capability enables users to change the backrest position while the assembled structure maintains stability during use

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The length parameter of the attachment assemblies can be changed by the user to adjust the backrest position. This parameter adjustment allows customization of seating comfort while maintaining structural integrity through secure attachment mechanisms

Inventive Principle:
Principle #35Parameter changes
