Solution Overview

Problem

Existing foldable lounge chairs lack integrated storage compartments for secure, insulated, and portable storage of personal items, making it difficult to transport and secure belongings while reducing strain on users and preventing theft.

Innovation Solution

A foldable and portable lounge chair with wheels, a telescoping handle, integrated storage compartments, an umbrella securing device, adjustable seating, insulated storage, and a locking mechanism to secure personal items, providing convenient accessibility and protection from environmental elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a user carries all personal items separately while transporting a lounge chair, then the user can bring desired items, but the user experiences increased physical strain and risk of losing or damaging items

Engineering Contradiction:
Improveease of transporting personal itemsVSAvoidphysical strain on user
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The patent combines the lounge chair with multiple integrated storage compartments into a single unified structure. The storage compartments are built into the chair frame, allowing users to store personal items like towels, beverages, and electronics within the chair itself rather than carrying them separately. This merging of storage functionality with the chair structure eliminates the need to transport items separately, reducing physical strain while maintaining ease of operation.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If personal items are stored in external containers while using a lounge chair, then items can be stored, but the user must constantly monitor and carry these containers, increasing physical burden

Engineering Contradiction:
Improveconvenience of storing personal itemsVSAvoidcombined weight of chair and items
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The patent positions storage compartments at various accessible locations on the lounge chair structure, including side compartments and under-seat storage. This distributes storage capacity throughout the chair rather than requiring a single heavy external container. Users can access items at their point of need without lifting or repositioning heavy external storage containers, effectively equalizing the effort required to access items regardless of location.

Inventive Principle:
Principle #12Equipotentiality

3Adaptability or versatility

If a lounge chair has no integrated storage compartments, then the structure remains simple, but users cannot securely store personal items within the chair

Engineering Contradiction:
Improvestorage capability of lounge chairVSAvoidstructural complexity of lounge chair
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the storage functionality into multiple separate compartments integrated into the chair structure. Rather than adding one large complex storage system, the design incorporates several smaller compartments at different locations (side compartments, under-seat storage, backrest pockets). Each compartment is a relatively simple structure that can be manufactured independently and assembled into the chair, maintaining manufacturing simplicity while providing versatile storage adaptability.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If storage compartments are not insulated, then the structure remains simple, but beverages and temperature-sensitive items cannot be kept cool

Engineering Contradiction:
Improvetemperature control capabilityVSAvoidinsulation structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies insulation specifically to the storage compartments that require temperature control, such as beverage holders and coolers, rather than insulating the entire chair structure. This localized insulation approach provides temperature control capability where needed while minimizing the addition of structural complexity. The insulated compartments use standard insulation materials and construction techniques that do not significantly complicate the overall chair design or manufacturing process.

Inventive Principle:
Principle #3Local quality

5Reliability

If a lounge chair lacks a locking mechanism, then the structure remains simple, but personal items are vulnerable to theft when unattended

Engineering Contradiction:
Improvesecurity of personal itemsVSAvoidlocking mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent incorporates a locking mechanism that can be operated by the user without requiring external assistance or complex security systems. The lock is integrated into the chair structure, allowing users to secure valuable items in storage compartments independently. This self-service locking capability provides reliable security for personal items while maintaining relatively simple construction, as the locking mechanism is a standard component integrated into the existing chair framework rather than a complex security system.

Inventive Principle:
Principle #25Self-service

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

Enables users to securely transport and store personal items, reduce strain during movement, and prevent theft by incorporating wheels, insulated storage, and a locking mechanism, while maintaining comfort and convenience.

Implementation Method 1

a cooler with a thermal insulating barrier located between the cooler and the external environment to prevent the cooled contents of the cooler from being compromised

Methodology Applied
Scientific EffectThermal insulation: Thermal Insulation

Implementation Method 2

the lounge chair is configured to roll resulting in a user pushing or pulling the lounge chair during transportation rather than struggling with carrying the lounge chair

Methodology Applied
Scientific EffectRolling friction: Friction

AI summary

A lounge chair equipped with wheels and is configured to be foldable by a user and has an integrated storage compartment with a locking mechanism. At least one storage compartment is integrated within the lounge chair. A user can access the storage compartment from the top of the storage housing when the seat portion is lifted to an open configuration or from the side of the storage housing when a user pulls out the storage housing drawer. When the seat portion is lowered to a closed position, a user is able to then sit on the seat portion and access at least a portion of a storage area through a pull-out drawer located on the side of the storage housing of the novel lounge chair. A handle portion can telescope from a closed configuration during storage to an open configuration when grasped by a user.
