Hands-Free Sign Holder With Shoulder Support for Crowd Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for conveying information through signs are limited by the need for manual holding, which is tiring and restricts mobility over long distances and durations.
Innovation Solution
A hands-free sign holder comprising shoulder-supported members, a rigid back structure, upright rods, and sign fasteners that allow easy and quick attachment of signs, enabling visibility above crowds and over long distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sign is held manually in the hand, then the sign can be displayed immediately, but the user experiences fatigue and limited mobility over long distances and durations
Solution Approach 1:
The sign holder is divided into separate functional components: a back structure for support, shoulder members for weight distribution, an upright rod for elevation, and a fastening mechanism for sign attachment. This segmentation allows each component to perform its specific function efficiently, enabling hands-free carrying for extended periods while maintaining sign visibility.
2Adaptability or versatility
If a sign is held manually, then no additional equipment is needed, but mobility is restricted and the user cannot perform other tasks
Solution Approach 1:
The sign holder is designed as a universal hands-free carrying system that can accommodate various sign sizes and types through its adjustable fastening mechanism. The device enables users to perform other tasks with their hands while displaying signs, making it versatile for protests, advertising, events, and guiding activities.
Solution Approach 2:
Instead of holding the sign with hands, the invention inverts the approach by supporting the sign on the user's back. This inversion transfers the weight burden from the hands to the shoulders and back structure, enabling hands-free operation and improved mobility.
3Ease of operation
If the sign holder structure is made more complex to enable hands-free carrying, then mobility is improved, but the device becomes more complicated
Solution Approach 1:
The upright rod acts as an intermediary element connecting the back structure to the sign fastening mechanism. This intermediate component allows the sign to be positioned at an elevated, visible height while maintaining a simple structural connection to the back support system, balancing functionality with structural simplicity.
