Height-adjustable table structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height-adjustable tables are inconvenient and unsafe due to hidden adjustment handles, requiring users to search by memory or bend down to adjust the height, leading to potential injuries.
Innovation Solution
A height-adjustable table structure with an adjustment member visible on the top surface and a linkage mechanism that includes a transmission rod and locking members, allowing intuitive adjustment and ensuring user safety by clearly visible operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adjustment handles are positioned under the tabletop for compact structure, then the device complexity is reduced, but the ease of operation deteriorates and safety hazards increase due to poor visibility
Solution Approach 1:
The adjustment member is extended from the traditional under-tabletop position to penetrate through the top surface of the tabletop, changing its spatial dimension from hidden below to visible above. This dimensional change allows users to clearly see and operate the adjustment member without bending down, improving visibility and ease of operation while maintaining structural compactness through the linkage mechanism
2Reliability
If the adjustment handles are hidden under the tabletop, then the manufacturing precision requirements are reduced, but the reliability deteriorates due to safety hazards from poor visibility
Solution Approach 1:
The adjustment mechanism is segmented into distinct functional components: the adjustment member penetrating the tabletop for visibility and operation, the linkage group with transmission rod and locking members for mechanical function, and the positioning members with multiple positioning grooves for precise height positioning. This segmentation allows each component to be optimized independently, improving safety through visibility while maintaining manufacturing feasibility
3Ease of operation
If the transmission rod rotates to drive the locking member between locking and releasing positions, then the ease of operation is improved, but the device complexity increases due to the linkage mechanism
Solution Approach 1:
The linkage group merges multiple functions into a single integrated mechanism: the transmission rod's rotation simultaneously drives the locking member to move between locking and releasing positions, controls the positioning member engagement with positioning grooves, and adjusts the tabletop height. This merging reduces the need for separate mechanisms for each function, improving ease of operation while keeping the overall device complexity manageable

AI summary
A height-adjustable table structure includes: a tabletop, a first support frame, a second support frame, a first spring, an adjustment unit, a linkage group, and a positioning member. The adjustment member is disposed to the top surface of the tabletop for the user to observe. When the adjustment member is driven to move, the locking member of the linkage group is moved from the locking position to the releasing position, so that the first and support frames are free to rotate. When the adjustment member is released, the locking member will be moved from the releasing position to the locking position, so as to maintain the adjusted height of the table structure. By such arrangements, during the height adjustment of the table structure, the user can clearly see the position of the adjustment member, leading to more intuitive use, achieving easy operation and improved safety.
