Solution Overview

Problem

Existing outdoor whirlpool claddings are prone to aging and require complex removal and reassembly for maintenance, lacking protection against mechanical and weather influences, and do not provide reversible access to the whirlpool technology.

Innovation Solution

A free-standing whirlpool cladding system with a frame and reversible cladding elements that can be attached and detached without fixing agents, providing protection and easy access to the whirlpool technology while maintaining structural stability and longevity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional outdoor whirlpool cladding is used, then protection against weather and mechanical damage is provided, but access to whirlpool technology for maintenance requires complex removal and reassembly

Engineering Contradiction:
ImproveAccess to whirlpool technologyVSAvoidCladding removal and reassembly complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cladding is divided into multiple individual cladding elements that are attached to the frame at discrete locations. Each cladding element can be independently removed by detaching it from the frame, eliminating the need to dismantle the entire cladding structure. This segmentation enables simple access to the whirlpool technology while maintaining the protective function of the complete cladding system.

Inventive Principle:
Principle #1Segmentation

2Reliability

If wood or plastic cladding is used for outdoor whirlpools, then visual appeal and protection are enhanced, but the materials are prone to aging and require periodic maintenance or replacement

Engineering Contradiction:
ImproveResistance to agingVSAvoidService life of cladding
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent changes the material parameters of the cladding elements by using metal materials (such as aluminum, stainless steel, or copper) instead of traditional wood or plastic. These metal materials have superior resistance to aging, weathering, and mechanical damage. The frame is also made of metal, creating a durable structural basis. This parameter change in material composition significantly extends the service life of the cladding system while reducing maintenance requirements.

Inventive Principle:
Principle #35Parameter changes

3Strength

If cladding is firmly attached to provide protection, then mechanical strength is improved, but access for maintenance becomes difficult and may create weak points at fixation points

Engineering Contradiction:
ImproveMechanical strength of claddingVSAvoidAccess for maintenance
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The attachment system is made dynamic by using detachable fastening mechanisms (such as clips, screws, or interlocking systems) that allow cladding elements to be easily attached and detached from the frame. This dynamic attachment provides sufficient mechanical strength when assembled while enabling simple removal for maintenance access. The fastening points are designed to maintain structural integrity during normal use but can be quickly released when maintenance is required, avoiding the creation of permanent weak points.

Inventive Principle:
Principle #15Dynamics

AI summary

An arrangement consisting of a whirlpool enclosure (1) and a freestanding outdoor whirlpool (2) with a whirlpool tub (2.1), whirlpool technology (2.2), and whirlpool outer shell (2.3), wherein the enclosure (1) comprises a frame (3) with a plurality of enclosure elements (5). The frame (3) is arranged around the whirlpool outer shell (2.3), and the enclosure elements (5) are attached to the frame (3) and comprise lateral vertical (5.1) and upper horizontal (5.2) enclosure elements (5). At least one lateral enclosure element (5.1) is reversibly attached to the frame (3) without the need for any fixings, so that it can be easily removed.
