Locking device and stabilizer for a stabilizing table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tables and chairs tend to rock and tip over on uneven surfaces, existing stabilization systems are not effective for various shapes and sizes, and require additional support to prevent wobble and instability.
Innovation Solution
A stabilizing system comprising a primary shaft and a secondary shaft with a locking mechanism, where the secondary shaft is inserted into the primary shaft and secured with a pivot and lock, providing self-stabilizing support on uneven surfaces and preventing wobble through the use of shims and additional support braces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a secondary shaft is inserted into a primary shaft to provide stabilization, then the table stability on uneven surfaces is improved, but the device complexity increases due to the additional locking mechanism and multiple shafts
Solution Approach 1:
The secondary shaft is inserted within the primary shaft, creating a nested configuration where the stabilizing element is contained within the main structural element. This nesting approach provides stabilization functionality while minimizing the overall space required and reducing visual complexity of the system.
Solution Approach 2:
The stabilization system is divided into distinct functional segments: the primary shaft for structural support, the secondary shaft for stabilization, the pivot for controlled movement, and the lock for securing. This segmentation allows each component to perform its specific function efficiently while enabling independent adjustment and maintenance of individual elements.
2Reliability
If a locking mechanism with pivot and lock is used to secure the secondary shaft, then the reliability of stabilization is improved, but the ease of operation deteriorates due to the complex locking and unlocking process
Solution Approach 1:
The pivot enables the secondary shaft to transition between fixed and movable states, allowing dynamic adjustment of the stabilization level. The lock provides a secure fixed state when needed, while the pivot mechanism allows easy release and repositioning when adjustment is required, balancing reliability with operational flexibility.
Solution Approach 2:
The pivot acts as an intermediary element between the secondary shaft and the locking mechanism, facilitating controlled movement and secure positioning. This intermediary component simplifies the interaction between the user and the stabilization system by providing a natural pivot point that guides the locking and unlocking actions.
3Manufacturing precision
If shims and additional support braces are added to prevent wobble, then the manufacturing precision requirements are reduced, but the device complexity increases
Solution Approach 1:
Shims are pre-positioned between the shaft components to compensate for manufacturing tolerances and surface irregularities before the final assembly is locked into place. This preliminary adjustment action allows the system to achieve proper alignment and eliminate wobble without requiring extremely tight manufacturing precision on all components.
Solution Approach 2:
Additional support braces are strategically positioned at specific locations where wobble and instability are most likely to occur, such as at the corners or edges of the table. This localized reinforcement approach provides targeted stabilization without requiring comprehensive strengthening of the entire structure, thereby minimizing added complexity.
