Walking Machine Upright Post Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current locking mechanisms for upright posts in walking machines are complex and pose safety concerns, leading to a poor user experience.
Innovation Solution
A locking mechanism comprising a first component fixed to the walking machine frame, a second component fixed to the upright post, and a third component with a connecting rod, wrench, and movable member with a spring, allowing for easy operation and safe stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a locking mechanism is added to fix the upright post in open or folded state, then the upright post can be stabilized, but the structure becomes more complex
Solution Approach 1:
The locking mechanism is divided into three independent components: a first component fixed to the frame, a second component fixed to the upright post, and a third component (movable member with spring) that moves between them. This segmentation allows each component to perform its specific function while keeping the overall structure manageable and not overly complex.
2Reliability
If a locking mechanism with multiple components is used, then the locking reliability is improved, but the operation becomes more complicated
Solution Approach 1:
The spring in the movable member provides automatic restoring force that pushes the movable member between the first and second components. This self-service mechanism eliminates the need for complex manual operations or additional actuators, making the locking and unlocking processes simple and intuitive while maintaining high reliability.
3Adaptability or versatility
If the upright post is designed to be foldable for transportation, then the portability is improved, but the safety during operation may be compromised
Solution Approach 1:
The locking mechanism transitions between two stable states: locked (upright post in open state) and unlocked (upright post in folded state). The movable member with spring dynamically adjusts its position based on the state of the upright post, ensuring that the post is securely locked during operation and can be easily folded for transportation when needed.
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 mechanism enables convenient and safe operation by limiting the relative motion between components, ensuring stability and ease of use when folding or erecting the upright post.
Implementation Method 1
a spring located at one end of the main body part far away from the protruding part; when the spring is not stressed, the second component can rotate relative to the first component

AI summary
The present disclosure provides a locking mechanism for an upright post of a walking machine, which comprises a first component fixed on a walking machine frame, a second component fixed on a upright post of the walking machine, and a third component movably arranged between the first component and the second component, wherein the first component is provided with a first accommodating groove, and the third component comprises a connecting rod, a wrench rotatably connected with the connecting rod, and a movable member partially accommodated in the first accommodating groove; the movable member comprises a protruding part protruding from the first accommodating groove, a main body part connected with the protruding part, and a spring located at one end of the main body away from the protruding part; when the spring is not stressed, the second component can rotate relative to the first component. The relative motion between the first component and the second component is limited by the position change of the movable component, which is easy to operate, safe and stable.
