Removable Roof Frame for Expandable Canopy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional collapsible canopies have limited versatility in roof configurations, making it difficult to display advertising materials effectively and increasing the complexity, weight, and cost of the framework, as well as requiring multiple canopy frames for different uses.
Innovation Solution
A removably mountable roof frame system that includes a base frame with upright support members and cross members, and a roof frame with adjustable rafters and ridge members, allowing for different roof configurations such as gabled, domed, or peaked designs, which can be easily changed and transported separately from the base frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the roof configuration is integrated into the expandable mechanism, then the roof configuration is fixed and structurally stable, but the framework complexity increases, weight increases, and adaptability decreases
Solution Approach 1:
The canopy framework is divided into two separate removable components: a base frame and a roof frame. The roof frame can be detached and replaced with different configurations (peaked, gabled, domed) while using the same base frame, thereby providing adaptability without permanently integrating the roof into the expandable mechanism.
Solution Approach 2:
A single base frame is designed to be compatible with multiple types of roof frames through standardized connection points. This universal design allows one base frame to support various roof configurations (peaked, gabled, domed) by simply changing the roof frame attachment, eliminating the need for multiple complete canopy frames.
2Adaptability or versatility
If multiple complete canopy frames are purchased for different roof configurations, then adaptability is achieved, but cost and device complexity increase
Solution Approach 1:
A single base frame is designed to be compatible with multiple types of roof frames through standardized connection points. This universal design allows one base frame to support various roof configurations (peaked, gabled, domed) by simply changing the roof frame attachment, eliminating the need for multiple complete canopy frames.
Solution Approach 2:
The roof frame is extracted as a separate removable component from the complete canopy assembly. This allows the roof frame to be independently replaced or changed without affecting the base frame, reducing the need to maintain multiple complete canopy frames for different configurations.
3Stability of the object's composition
If the roof frame is permanently attached to the base frame, then structural stability is improved, but weight increases and ease of operation decreases
Solution Approach 1:
The canopy framework is divided into two separate removable components: a base frame and a roof frame. This segmentation allows each component to be optimized independently and transported separately, reducing the weight burden during transport while maintaining structural stability when assembled.
Solution Approach 2:
The connection between the roof frame and base frame is designed to be dynamically changeable - securely attached during use for stability, but easily detachable for reconfiguration or transport. The quick-attach mechanism allows the system to transition between stable operational state and lightweight transport state.
4Object-affected harmful factors
If the peaked configuration is used, then water shedding is effective, but advertising display area is reduced
Solution Approach 1:
The roof configuration is made dynamically changeable by allowing replacement of the roof frame. Users can select a peaked roof configuration when water shedding is the priority, and switch to a flat or low-profile configuration when maximum advertising display area is needed, optimizing for different operational requirements.
Solution Approach 2:
The same base frame supports multiple roof configurations including peaked (for water shedding) and flat/low-profile (for advertising display). This multi-functionality allows the canopy to adapt its roof shape based on whether the primary need is weather protection or advertising visibility.

AI summary
An erectable canopy framework comprising a base frame and a roof frame. The roof frame is operative to support a canopy above the base frame and is removably mountable to the base frame. The base frame includes a plurality of upright support members, a plurality of cross members, each interconnecting adjacent upright support members, and a plurality of mounts disposed on the upright support members. Each mount includes a mount opening and each cross member includes a scissor assembly to permit movement of the base frame between expanded and a collapsed states. The mounts are operative to fasten the cross members to the upright support members. The roof frame includes a plurality of rafters each connectable to a corresponding mount opening. The framework comprises a plurality of rafter fittings each adapted for insertion into a corresponding mount opening and connectable to a corresponding rafter.
