Convertible Top Device with Pivotable Supports and Adjustable Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing convertible top devices for golf carts are cumbersome, expensive to install, lack versatility, and do not provide adequate protection from the elements, with many being permanently fixed and unstable, especially in varying weather conditions.
Innovation Solution
A lightweight, easy-to-install convertible top device with a frame assembly that includes a main frame support, forward and rearward supports, and a top cover that can be securely attached to the vehicle using adjustable straps, allowing for seamless conversion between open and stowed positions, and featuring a protective storage bag for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a convertible top device is designed to be selectively convertible between open and stowed positions, then ease of operation and adaptability are improved, but device complexity increases due to the need for pivotable supports and convertible mechanisms
Solution Approach 1:
The top device is divided into separate functional components: a frame assembly with pivotable supports, a convertible top cover, and a storage bag. This segmentation allows each component to be optimized independently and simplifies the overall conversion mechanism between open and stowed positions.
Solution Approach 2:
The frame assembly incorporates pivotable supports that enable dynamic conversion between open and stowed positions. The supports can rotate about pivot points, allowing the top to transition smoothly between operational and storage states without complex locking or fastening mechanisms.
2Ease of manufacture
If the top device is made lightweight and easy to install, then ease of manufacture and ease of operation are improved, but structural strength and stability may be compromised
Solution Approach 1:
The top cover is constructed from a flexible yet durable material that provides adequate protection while maintaining lightweight properties. This flexible shell approach eliminates the need for heavy rigid structures while still providing effective coverage against elements.
Solution Approach 2:
The frame assembly uses composite construction combining lightweight materials with strategic reinforcement at critical joints and pivot points. This allows the overall structure to remain lightweight and easy to install while maintaining sufficient strength and stability during operation.
3Stability of the object's composition
If permanently fixed top assemblies are used, then structural stability is improved, but adaptability and ease of operation deteriorate as users cannot selectively enjoy sun or favorable weather
Solution Approach 1:
The pivotable supports enable the top device to transition dynamically between fixed stable positions (open) and folded storage positions (stowed). The pivot joints provide inherent stability when opened while allowing easy conversion to storage mode, giving users selective control over protection levels.
Solution Approach 2:
The adjustable straps serve as intermediaries that secure the top device in the open position, providing stable fixation when needed while allowing easy release when users want to enjoy sun or favorable weather. This mediator mechanism bridges the stability requirement with adaptability needs.
4Strength
If fixed top assemblies are permanently affixed to the vehicle frame, then structural support is improved, but ease of installation and adaptability worsen
Solution Approach 1:
The top device is designed as a separate, self-contained unit with its own frame assembly, rather than being permanently integrated into the vehicle structure. This segmentation allows for easy installation and removal while maintaining adequate structural support through the dedicated frame design.
Solution Approach 2:
Adjustable straps and mounting mechanisms serve as intermediaries between the top device and the vehicle frame, providing sufficient structural support during operation while allowing easy installation and removal without permanent modification to the vehicle.

AI summary
A convertible top device for a vehicle includes a main frame support pivotally attached to a vehicle, a forward support pivotally attached to the main frame support, a rearward support pivotally attached to the main frame support and a top extended over the forward support, main support and the rearward support. At least one strap is interconnected between the forward support and a forward end of the vehicle and the rearward support and the rearward end of the golf cart. The top device is convertible between an open position and a stowed position at the rearward end of the vehicle.
