Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desks lack adjustable height mechanisms, making it inconvenient and unsafe for users of different heights to operate, as existing lifting-lowering solutions are cumbersome and limited in height adjustment.
Innovation Solution
A manual lifting-lowering computer table design featuring sliding seats, hinged supporting feet with telescopic devices, and a handle mechanism that allows for adjustable height, enabling users to adapt the table height for sitting or standing positions while maintaining a stable center of gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lifting-lowering mechanism is added to the computer table, then the height adjustability is improved, but the device complexity increases
Solution Approach 1:
The patent applies dynamics by making the table board height adjustable through a lifting-lowering mechanism. The table board can transition between fixed and movable states, allowing it to adapt to different user heights and working positions (sitting or standing), thus resolving the contradiction between height adjustability and structural complexity.
Solution Approach 2:
The lifting-lowering mechanism is segmented into independent components: sliding seats on the table board, supporting feet with telescopic devices, and hinge connections. This segmentation allows the complexity to be distributed and managed through modular components rather than a monolithic complex structure.
2Device complexity
If the table board lifting-lowering height is limited, then the device complexity is reduced, but the ease of operation deteriorates due to the need for additional display height adjustment
Solution Approach 1:
The patent merges the table board lifting-lowering function with the display height adjustment by providing sufficient lifting range. The table board can be raised high enough to accommodate standing work positions, which simultaneously provides adequate display height without requiring separate adjustment mechanisms, thus combining multiple functions into one system.
Solution Approach 2:
The lifting-lowering mechanism serves multiple functions: it adjusts the table board height for different user preferences (sitting or standing), and simultaneously provides sufficient display height. This multi-functionality eliminates the need for separate display adjustment mechanisms, improving ease of operation while maintaining relatively simple structure.
3Ease of operation
If the table board is made foldable for storage, then the ease of operation is improved, but the stability of the object's composition deteriorates during use
Solution Approach 1:
The table board is designed with dynamic characteristics, being foldable for storage and transport but providing structural stability during use through the lifting-lowering mechanism and supporting feet. The structure transitions between folded and unfolded states, achieving both storage convenience and operational stability.
Solution Approach 2:
The supporting feet with telescopic devices are pre-positioned to provide stability when the table board is in use. The hinge connections and sliding seats are pre-configured to ensure proper alignment and structural integrity during the folded and unfolded transitions, maintaining stability throughout the operational cycle.

Function Achieved in This Case
Enables convenient and safe height adjustment to reduce the risk of musculoskeletal disorders and facilitates easy storage and transportation by allowing the table to be folded.
Implementation Method 1
The first supporting foot is provided with a supporting telescopic device. An upper end of the supporting telescopic device is hinged on the connecting seat, and the connecting seat is arranged at one end of the sliding seat adjacent to the keyboard board; and a lower end of the supporting telescopic device is arranged on an upper part of the first supporting foot.
Implementation Method 2
The middle part of the first supporting foot and the middle part of the second supporting foot are hinged through a connecting shaft
