Pivoting Table Frame Locking Structure for Stability and Wear Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tilting tables face a trade-off between stability and cost-effectiveness, often compromising on user convenience and durability due to the use of thin-walled materials in their frame and locking mechanisms, leading to instability and wear over time.
Innovation Solution
A table frame design featuring a separate, thicker, and more wear-resistant second fixing element that can be fixedly connected to the base frame and crossmember, allowing for multi-stage locking with angled clamping surfaces to enhance stability and durability, while maintaining cost-effectiveness and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If thin-walled tubes or section tubes are used for the support frame and crossmember to reduce weight and cost, then cost-effectiveness and weight are improved, but stability and rigidity deteriorate
Solution Approach 1:
The locking mechanism is segmented into separate components: a first fixing element integrated into the crossmember and a second fixing element that is separate and can be replaced. This segmentation allows the main frame to remain lightweight while the separate fixing element provides enhanced stability and wear resistance where needed.
Solution Approach 2:
Instead of making the entire frame thick-walled, the invention applies enhanced material properties locally at the fixing elements. The second fixing element is made as a separate component with appropriate thickness and material quality specifically at the locking interface, while the rest of the frame can remain thin-walled for cost-effectiveness.
2Ease of manufacture
If thin-walled materials are used in the locking mechanism, then cost-effectiveness is improved, but durability and wear resistance deteriorate
Solution Approach 1:
The second fixing element is designed as a replaceable component that can be worn or damaged without affecting the entire table frame. If this element wears out, only this single component needs to be replaced rather than the entire locking mechanism or frame, improving long-term durability while keeping individual component costs low.
Solution Approach 2:
The invention changes the material parameter (thickness, material quality) specifically for the fixing elements compared to the rest of the frame. This localized parameter change ensures durability at critical wear points while maintaining cost-effectiveness for the overall structure.
3Device complexity
If the crossmember serves both structural and locking functions, then device complexity is reduced, but manufacturing precision and stability deteriorate
Solution Approach 1:
The locking function is segmented from the structural function. The crossmember provides structural support while the separate first and second fixing elements provide the locking function. This segmentation allows each component to be optimized for its specific function without compromising the other.
4Device complexity
If the fixing element is integrated into the crossmember, then device complexity is reduced, but ease of repair and replacement deteriorate
Solution Approach 1:
The fixing elements are segmented as separate replaceable components rather than being permanently integrated into the crossmember. This allows the second fixing element to be easily replaced if worn or damaged, while the overall structure remains simple and the number of additional components is minimal.
