Solution Overview
Problem
Existing beach carts are not compact enough for transportation, lack sufficient storage compartments, and are difficult to maneuver, especially on sand and stairs, due to their size and weight, and do not provide power generation features for charging batteries or personal devices.
Innovation Solution
A foldable motorized beach cart with a collapsible frame and storage compartments, equipped with a tubular motor drive system, solar panels for power generation, and a drive track for efficient movement on various surfaces, including sand and stairs, and features for easy storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cart is made compact for transportation, then it can be easily packed in the car, but it may be difficult to provide sufficient storage compartments and stable structure
Solution Approach 1:
The cart body is divided into multiple storage compartments including a first storage compartment, second storage compartment, and third storage compartment. Each compartment serves specific storage needs, allowing the cart to provide adequate storage capacity while maintaining a compact overall structure that can be folded for transportation.
Solution Approach 2:
The cart employs a nested structure where the rear portion is foldable within the sidewalls of the middle portion, and the front portion is foldable over the middle portion. This nesting approach allows the cart to collapse into a compact configuration for storage and transportation while expanding to provide sufficient storage space when in use.
2Ease of operation
If the cart is made motorized to reduce physical burden, then it can easily traverse sand and stairs, but it increases weight and complexity
Solution Approach 1:
The motorized cart integrates multiple functions into a single system: the motor drive system provides propulsion for traversing various surfaces, the battery pack supplies power, and solar panels offer auxiliary charging. This multi-functional integration reduces the need for separate systems, thereby managing complexity while enhancing ease of operation.
Solution Approach 2:
The cart incorporates solar panels that can charge the battery pack during use, allowing the system to partially self-recharge and reduce dependence on external power sources. This self-service capability reduces the overall system complexity by eliminating the need for frequent manual battery replacements or external charging equipment.
3Productivity
If the cart provides multiple storage compartments, then it can carry different beach items efficiently, but it increases the overall size and weight
Solution Approach 1:
The storage system is segmented into multiple specialized compartments: a first storage compartment for general items, a second storage compartment for cooler items with insulation, and a third storage compartment for personal belongings. This segmentation allows efficient organization and transport of different beach items without requiring excessive overall cart size or weight.
Solution Approach 2:
The cart utilizes composite materials including an insulated panel in the second storage compartment that combines insulating material with structural support. This composite approach provides the necessary thermal insulation for keeping items cool while maintaining structural integrity and minimizing additional weight.
4Volume of moving object
If the cart is designed to be folded for compact storage, then it can be easily transported in the car, but it may compromise structural stability and ruggedness
Solution Approach 1:
The cart employs a nested folding structure where the rear portion folds within the middle portion's sidewalls, and the front portion folds over the middle portion. This nesting design maintains structural stability during folding and unfolding operations while achieving a compact storage configuration that fits in a car.
Solution Approach 2:
The cart incorporates curved support structures and rounded corners in its frame design that provide structural reinforcement during folding operations. The curved geometry distributes stress more effectively than sharp angles, maintaining structural stability while allowing the cart to collapse into a compact form for transportation.
