Walking Stick Seat Structure for Stable Two-Legged Stool Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-legged shooting sticks are unstable when used as stools, requiring users to maintain a specific foot arrangement to ensure stability.
Innovation Solution
A pair of walking sticks with releasably attachable seat members that form a two-legged stool, allowing users to sit with feet at the corners of a rectangle or triangle for stability, featuring telescopically adjustable and lockable stick members and pivotable seat components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-legged shooting stick is used as a stool, then the device can be used for sitting, but the stability is poor and requires specific foot arrangement
Solution Approach 1:
The invention divides the single-legged shooting stick into two separate stick members, each with its own seat member. These two members work together to form a stable two-legged stool structure, eliminating the instability inherent in single-legged designs while maintaining the versatility of being usable as walking sticks or stools.
Solution Approach 2:
The invention combines two walking sticks with pivotally mounted seat members to create a unified two-legged stool structure. The seat members are designed to work together when opened out, forming a stable seating surface that distributes weight across two legs rather than one, thereby improving stability.
2Adaptability or versatility
If the seat members are opened out to form a seat, then the shooting stick can be used as a stool, but the structure becomes less stable
Solution Approach 1:
The invention segments the stool structure into two separate stick members with individual seat members, allowing each to be independently positioned and locked. This segmentation enables the formation of a two-legged stool that is inherently more stable than a single-legged design while maintaining the ability to convert between walking stick and stool configurations.
Solution Approach 2:
The invention employs dynamically adjustable seat members that can pivot between closed (walking stick) and opened (stool) positions. The seat members are prevented from pivoting beyond their first position, providing automatic mechanical locking that maintains structural stability in the stool configuration without requiring additional locking mechanisms.
3Adaptability or versatility
If the stick members are made telescopically adjustable, then the equipment can suit different users and uses, but the device complexity increases
Solution Approach 1:
The invention divides each stick member into telescopic sections that can be independently adjusted in length. This segmentation allows for compact storage when the walking sticks are not in use and enables height adjustment to suit different users and applications, from walking sticks to stools, without significantly increasing overall complexity.

AI summary
A seat using a pair of walking sticks. A seat member is formed adjacent the top end of the walking sticks. The walking sticks are releasably attached to one another adjacent top ends of the walking sticks so that seat members together form a seat, and the walking sticks diverge from the seat to form a two-legged stool. Each seat member is pivotally mounted to the top end of the respective walking stick for movement between a deployed position in which the seat extends at an acute angle from the top end of the walking stick, and a stowed position in which the seat extends alongside the respective walking stick.
