Adjustable Lifting Support Device with Tooth-Engagement Height Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional support frames for portable electronic devices, such as notebook and tablet computers, are typically fixed in height, failing to accommodate the varying heights and preferred viewing angles of different users, leading to shoulder and neck strain due to inadequate ergonomic support.
Innovation Solution
An adjustable lifting support device featuring a base with a connecting part and a lifting rod with teeth, an adjusting device with a connecting holder and an engaging member linked by an elastic element, allowing precise height adjustment of the support plate to align with the user's view angle, incorporating an inclined support surface for stability and effortless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-type support frame is used, then the structure is simple and stable, but the height cannot be adjusted to accommodate different users' viewing angles
Solution Approach 1:
The support frame transitions from a fixed structure to a dynamic adjustable structure. The connecting holder can be moved along the lifting rod to different positions and locked at each position using the engaging member and teeth mechanism, allowing the height to be adjusted according to different users' needs while maintaining structural stability when locked.
Solution Approach 2:
The lifting rod is divided into multiple segments marked by teeth at different positions. The engaging member can engage with different teeth to lock the connecting holder at various heights, enabling discrete height adjustments. This segmentation allows for multiple fixed positions while maintaining a relatively simple overall structure.
2Ease of operation
If an adjustable mechanism is added to the support frame, then height adjustment is enabled, but the operation becomes more complex and time-consuming
Solution Approach 1:
The engaging member is designed to engage with only one tooth at a time rather than requiring complex multi-point locking. The user simply needs to release the engaging member, move the connecting holder to the desired position, and let the elastic element automatically engage with the nearest tooth, minimizing adjustment time and effort.
Solution Approach 2:
The elastic element automatically engages the engaging member with the teeth when the connecting holder is moved to a new position. This self-locking mechanism eliminates the need for manual locking operations, reducing both the complexity of operation and the time required for adjustment.
3Stability of the object's composition
If the rod is positioned vertically during assembly, then alignment is easier, but the connecting holder may fall directly and quickly without resistance
Solution Approach 1:
The inclined support surface is designed to provide preliminary resistance against the connecting holder's downward movement. When the rod is positioned vertically during assembly, the inclined surface creates a controlled deceleration effect, preventing the connecting holder from falling directly and quickly by opposing the gravitational force in advance.
Solution Approach 2:
The inclined support surface acts as a cushioning mechanism before the connecting holder reaches its final position. It provides a gradual deceleration rather than an abrupt stop, reducing the impact and preventing sudden falls during the assembly process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise height adjustment of the support plate to reduce shoulder and neck strain by accommodating individual user preferences, providing ergonomic comfort and ease of use through a simple and efficient operation mechanism.
Implementation Method 1
an elastic element disposed in the accommodating groove, and two ends of the elastic element are abutted between the accommodating groove and the connecting holder
Implementation Method 2
the rod of the inclined lifting rod can provided resistance to prevent the connecting holder of the adjusting device from falling directly and quickly
Implementation Method 3
after the rod of the lifting rod is fixed on the connecting part of the base, a support surface of a back side of the combination groove of the combination holder is inclined, and a back side of the rod can be abutted against the inclined support surface

AI summary
An adjustable lifting support device is disclosed. The adjustable lifting support device includes a base, a lifting rod and an adjusting device. The base includes a placing plate and a connecting part disposed on the placing plate. The lifting rod includes a rod disposed on the connecting part and including teeth arranged longitudinally. The adjusting device includes a connecting holder mounted on the rod, and the bottom of the connecting holder is pivotally connected to an engaging member which is jointed with a linking device. The placing plate can be placed on desktop and a support plate disposed on the connecting part can be adjusted in position. The linking device can be used to drive the engaging member to engage with or separate from the teeth of the lifting rod, so that the connecting holder can be slidably lifted and locked on the rod of the lifting rod.
