Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool wagons face difficulties in assembly due to complex welding processes and loose connections, leading to instability and low loading capacity when overloaded.
Innovation Solution
A post with a hollow structure and slide mechanism, featuring engagement mechanisms with through openings and blocking portions, allows for easy assembly and enhanced stability by providing frictional resistance and secure attachment of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding process is used to connect frame with body, then connection strength is improved, but manufacturing complexity increases
Solution Approach 1:
The patent replaces the welding process with a mechanical connection system consisting of posts inserted into hollow structures with engagement mechanisms. This substitution eliminates the need for welding operations while maintaining connection strength through the blocking portion that prevents detachment, thereby reducing manufacturing complexity without sacrificing structural integrity.
2Stability of the object's composition
If screwing members are used to join frame joints, then connection stability is improved, but assembly time increases
Solution Approach 1:
The frame is segmented into modular components (posts and hollow structures) that can be assembled independently. Each post with its engagement mechanism functions as a self-contained unit that can be quickly inserted and locked into place, eliminating the need for time-consuming screwing operations at each joint while maintaining stability through the blocking portion design.
Solution Approach 2:
The engagement mechanisms (blocking portions) are pre-formed as integral parts of the hollow structures during manufacturing. This preliminary preparation allows for rapid assembly where posts are simply inserted and automatically locked, eliminating the need for on-site fastening operations and significantly reducing assembly time while ensuring stable connections.
3Ease of operation
If tight-fitting method is used to connect components to posts, then assembly ease is improved, but connection reliability deteriorates under overload
Solution Approach 1:
The blocking portions are pre-formed within the hollow structures during manufacturing, creating ready-to-lock engagement mechanisms. This preliminary action allows components to be easily inserted (maintaining assembly ease) while the blocking portions automatically engage to provide secure mechanical interlocking (ensuring reliability under overload conditions).
Solution Approach 2:
The blocking portion acts as an intermediary element between the post and the component being attached. It provides a mechanical interface that transforms the simple insertion motion (easy assembly) into a secure locked connection (reliable under overload) by preventing reverse movement and distributing loads effectively.
4Reliability
If engagement mechanism is added to slides, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The engagement mechanism (blocking portion) is merged with the slide structure as an integral feature rather than a separate component. The blocking portion is formed within the hollow structure of the slide, combining the sliding function with the engagement function in a single element, thereby improving connection reliability without significantly increasing overall device complexity.
Solution Approach 2:
The hollow structure with the blocking portion serves multiple functions: it provides the structural framework for the slide, enables the engagement mechanism for secure connection, and allows for the insertion and retention of various components. This multi-functionality improves reliability without requiring additional dedicated components, thus avoiding excessive complexity.
