Shade tarp using advertising balloon
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shade tarps and advertising balloons face issues such as poor ventilation, heat buildup, obstruction of views, difficulty in placing equipment, and susceptibility to wind collapse, leading to increased installation costs and potential damage from strong winds.
Innovation Solution
A shade tarp system utilizing an advertising balloon with a frame that is lifted into the air by gas injection, featuring a cover portion that is upward-movably connected to the frame, allowing ventilation between the frame and cover portion, and incorporating a double-layer frame structure to prevent gas leakage, while providing shade and reducing installation costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a shade tarp is installed with supports to prevent sagging, then structural stability is improved, but it becomes difficult to place equipment such as large chairs or tables in the event space
Solution Approach 1:
The patent uses helium gas injection to create buoyant force that counteracts the weight of the shade tarp, lifting it off the ground and eliminating the need for support pillars. This allows equipment to be freely placed underneath while the tarp remains stable in the air.
Solution Approach 2:
The patent employs gas (helium) injection into the frame structure to provide lifting force, replacing traditional mechanical support systems. The pneumatic buoyancy mechanism enables the shade tarp to maintain stability without ground-based supports that would obstruct equipment placement.
2Ease of operation
If a shade tarp is installed without supports to allow equipment placement, then ease of operation is improved, but the central portion sags due to gravity
Solution Approach 1:
Helium gas injection provides upward buoyant force that counteracts gravitational pull on the tarp, preventing sagging in the central portion while allowing the structure to remain support-free for equipment placement.
Solution Approach 2:
The gas-filled frame structure uses pneumatic pressure to maintain structural rigidity and prevent gravitational sagging, eliminating the need for mechanical supports while preserving structural integrity.
3Stability of the object's composition
If a shade tarp is installed low to the ground for stability, then structural stability is improved, but ventilation is poor and the space under the shade tarp becomes too hot
Solution Approach 1:
By lifting the shade tarp into the air using helium buoyancy, the patent creates ground clearance that enables air circulation and ventilation underneath, reducing heat buildup while maintaining structural stability through aerostatic support.
Solution Approach 2:
The gas-injected frame elevates the tarp structure, creating space for convective air flow underneath. This pneumatic lifting mechanism simultaneously achieves stability and thermal comfort by enabling natural ventilation.
4Area of stationary object
If an advertising balloon is made large for visibility, then advertising effectiveness is improved, but the rope may break or the balloon may be damaged due to strong wind
Solution Approach 1:
The patent divides the large advertising balloon into a modular frame structure with internal ribs and segments. This segmentation reinforces the overall structure against wind loads while maintaining large visibility area, preventing rope failure and balloon damage.
Solution Approach 2:
The advertising balloon uses a composite structure combining frame elements with fabric or film covering. This composite construction enhances wind resistance and structural integrity while preserving the large surface area needed for advertising visibility.
5Area of stationary object
If a shade tarp is installed wide, long, and high for coverage, then shading effectiveness is improved, but the shade tarp may collapse due to strong wind and installation cost may increase
Solution Approach 1:
The large shade tarp is constructed with a segmented frame structure containing internal ribs and divisions. This segmentation distributes wind loads across multiple smaller sections, preventing collapse while maintaining large overall coverage area, and reduces material costs through efficient structural design.
