Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional operation table boards and gangplanks have fixed lengths, limiting their versatility and application scope, as they cannot be easily adjusted to meet different requirements in various situations, such as domestic mini scaffolds or vehicle washing tasks, and occupy excessive space when not in use.
Innovation Solution
A telescopic table board with a resilient pin mechanism, allowing the left and right table boards to slide nestedly, featuring a rack and seat bore with a positioning fastener and spring, enabling adjustable length through a resilient-pin type telescopic positioning mechanism for convenient extension and locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the table board is designed with a fixed length, then the structure is simple and easy to manufacture, but the versatility and adaptability are poor
Solution Approach 1:
The table board is divided into multiple segments (first table board and second table board) that can slide relative to each other. The first table board includes a rack, while the second table board includes a pin with a positioning fastener and spring mechanism, allowing the board to be segmented into telescopic sections for adjustable length.
Solution Approach 2:
The table board transitions from a static fixed-length structure to a dynamic telescopic structure. The pin can move between locked and unlocked positions, enabling the table board to dynamically adjust its length based on application requirements, improving adaptability while maintaining operational simplicity.
2Volume of moving object
If the table board is designed with a fixed length, then the manufacturing cost is low, but it occupies excessive space when not in use
Solution Approach 1:
The second table board is nested within the first table board in a telescopic configuration. When collapsed, the boards nest together to minimize storage volume. The pin and positioning fastener mechanisms are integrated within the board structure, allowing compact storage while maintaining ease of manufacture through modular components.
3Adaptability or versatility
If the table board is designed with a fixed length, then the structure is stable, but it cannot be flexibly adjusted for different application occasions
Solution Approach 1:
The spring-loaded positioning fastener automatically engages with the rack teeth to lock the table board at the desired length without requiring additional tools or complex locking mechanisms. The spring provides continuous pressure to maintain the locked position, ensuring structural stability while allowing easy adjustment when the release button is pressed.
Solution Approach 2:
The positioning fastener uses a simple spring mechanism with rack teeth that can be manufactured at low cost. The spring and fastener components are designed as simple, robust parts that provide reliable locking without complex mechanisms, maintaining structural stability while enabling frequent adjustment for different applications.
4Volume of moving object
If the gangplank is designed with a fixed length, then the structure is simple, but it cannot be folded and occupies too much area
Solution Approach 1:
The gangplank transforms from a static fixed-length structure to a dynamic telescopic structure. The pin with positioning fastener and spring mechanism allows the gangplank to extend or collapse, reducing storage area when not in use while maintaining structural integrity during use.
Solution Approach 2:
The telescopic sections of the gangplank nest within each other when collapsed, minimizing the storage footprint. The first and second table boards slide into each other, with the pin and fastener mechanisms integrated within the board structure, allowing compact storage without adding significant complexity.
