Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temporary signage systems are cumbersome to set up and take down, prone to damage, and lack versatility in handling signs of varying sizes, especially in windy or uneven conditions, and often require anchoring that is not feasible on all surfaces.
Innovation Solution
A foldable display system comprising three frames with rotatable hinges and a linkage assembly that creates a stable base structure, allowing for easy setup and takedown, and featuring anchoring locations and wheels for mobility, along with placard engaging tabs for secure and adjustable signage display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional banner pop up signs are used, then temporary signage can be provided, but they are difficult and cumbersome to set up and collapse
Solution Approach 1:
The sign structure is divided into multiple collapsible sections that can be easily folded and stored. The frame is segmented into telescopic components that nest within each other, allowing quick deployment and compact storage without complex assembly procedures.
Solution Approach 2:
The sign incorporates telescopic poles with lockable mechanisms that allow dynamic adjustment of height and configuration. The structure transitions between extended display mode and collapsed storage mode through simple mechanical operations, enhancing ease of setup while maintaining structural integrity.
2Reliability
If traditional banner signs are used, then temporary display is achieved, but they can be easily blown away by wind and require anchoring
Solution Approach 1:
The sign structure incorporates weighted bases or counterweight mechanisms that provide stability against wind forces. The weighted design allows the sign to stand firmly without requiring ground anchoring, maintaining reliability in windy conditions while preserving ease of installation on various surfaces.
3Reliability
If anchoring with stakes is used, then stability is improved, but it is limited to grassy areas and cannot be used on concrete or blacktop
Solution Approach 1:
The sign is designed with multiple installation options including weighted bases for hard surfaces, adhesive mounting capabilities, and adjustable anchoring systems that work on both grassy and paved areas. This multi-functional design provides stability across diverse surfaces without requiring surface-specific anchoring methods.
4Strength
If framed posters are used, then support structure is provided, but framing is cumbersome and difficult to travel with
Solution Approach 1:
The frame structure is designed with nested telescopic sections that collapse into each other for compact storage. The framing components nest within a portable carrying case, maintaining structural support strength while significantly reducing size for easy transport and storage.
5Adaptability or versatility
If hand-made temporary signage is used, then flexibility is achieved, but appearance is unprofessional
Solution Approach 1:
The sign structure incorporates standardized professional-grade framing and mounting mechanisms that ensure a polished appearance. The system accepts various sign materials and configurations while maintaining structural integrity and professional presentation, bridging the gap between flexibility and professional quality.
6Reliability
If formal mounted signage is used, then professional appearance is achieved, but it is expensive and time-consuming to install
Solution Approach 1:
The sign components are pre-assembled and pre-configured during manufacturing with integrated mounting hardware and adjustable mechanisms. This preliminary preparation allows for rapid on-site deployment while maintaining professional appearance, significantly reducing installation time compared to custom-mounted solutions.
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
The system provides a quick, professional, and stable display solution that can withstand weather and uneven surfaces, accommodating various sign sizes and allowing easy relocation, while being lightweight and easy to transport.
Implementation Method 1
A first frame hinge rotatably couples the first frame to the second frame about a first axis. A second frame hinge rotatably couples the second frame to the third frame about a second axis.
Implementation Method 2
A linkage assembly is attached to the first frame and to the second frame. The linkage assembly limits the maximum angle between the first frame and the second frame about the first frame hinge when the linkage assembly is fully extended.
Implementation Method 3
The foldable display includes a clasp having a clasp hinge. The clasp is attached to the third frame at a first clasp end and via the clasp hinge. The clasp is rotatable about the clasp hinge. The clasp is attachable to the first frame at a second clasp end opposite the first clasp end.
