Pivoting Leg Supports for Portable Voting Booth Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable voting booths often lack stability due to inadequately supported legs, which can wobble during use, and are difficult to disassemble for storage.
Innovation Solution
A portable voting booth design featuring removable legs stabilized by leg supports that can be moved between open and closed positions, using frictional grips and hinged connections to secure the legs during use and compactly store them when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If removable legs are used in portable voting booths, then ease of disassembly for storage is improved, but stability during use deteriorates because legs can wobble and are not securely held in place
Solution Approach 1:
The leg support structure is designed to be dynamic rather than static. The support arms can pivot between a retracted position (for compact storage) and an extended position (for stabilizing the legs during use). This dynamic mechanism allows the same structure to serve two opposing functions: enabling easy disassembly while maintaining stability during operation.
Solution Approach 2:
The support arms act as intermediary elements between the base and the legs. These arms provide the necessary stabilization force to prevent leg wobble, while being independently controllable. The intermediary support arms allow the legs to remain removable and easy to detach while still providing the stability that direct attachment would provide.
2Stability of the object's composition
If legs are securely attached to prevent wobble, then stability is improved, but ease of disassembly for storage deteriorates
Solution Approach 1:
The attachment mechanism is designed to be dynamically adjustable. The support arms can be quickly pivoted into position to stabilize legs during use, and just as quickly retracted to allow easy disassembly. This dynamic control allows the system to transition between stable and easily disassembled states without permanent attachment.
Solution Approach 2:
The support structure is segmented into independent support arms that can be individually controlled. Each support arm can be independently positioned to stabilize a leg, or retracted to allow leg removal. This segmentation allows partial stabilization without requiring complete permanent attachment of all components.
3Stability of the object's composition
If leg supports are always extended to stabilize legs, then stability is improved, but device complexity and storage difficulty increase
Solution Approach 1:
The support arms are designed to be dynamically positionable rather than permanently fixed in an extended position. They can be pivoted into the extended position when stability is needed, and retracted when storage or transport is required. This dynamic positioning reduces the effective complexity during storage while maintaining stability during use.
Solution Approach 2:
The support arms can be nested or folded into the base structure when not in use. The arms pivot to align with the base, creating a compact nested configuration that minimizes storage space and reduces apparent device complexity, while still providing full stabilization capability when deployed.

Function Achieved in This Case
The design provides a stable voting booth during use and allows for easy disassembly and storage, preventing leg movement and ensuring a secure voting experience.
Implementation Method 1
the inner surface of the mouth includes an overmolded piece formed from rubber, plastic, thermoplastic elastomer (TPE) or similar materials so as to frictionally grip the portion of the leg received within the mouth
Implementation Method 2
The leg support also includes a hinged connection to the table in the form of a pin and knuckle

AI summary
A portable voting booth that includes a table having a top surface and a bottom surface, a plurality of legs configured to support the table, and a plurality of leg supports attached to the table and configured to stabilize the legs during use of the voting booth. In some embodiments, the leg supports are movable from an open position to a closed position in which the leg supports are immovably secured to the table for storage. Preferably, the leg supports are disengaged from the legs and generally flush with the bottom surface of the table when the leg supports are in the closed storage position.
