Lift Stand Stroke Locking for Compact Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lift stands lack stroke fixing capability, leading to increased packaging size and potential instability during assembly due to weight, and existing stroke fixing devices have complex structures that increase costs and assembly time.
Innovation Solution
A positionable lift stand design featuring a support structure, sliding member, elastic member, and fixing member, where the sliding member is actuated by the elastic member's restoring force, allowing height adjustment and fixation using fewer parts and simpler manufacturing processes, reducing packaging size and assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the lift stand is left at its maximum reach, then the height adjustment function is available, but the packaging size increases
Solution Approach 1:
The lift stand is designed with a stroke fixing capability that allows the sliding member to be preliminarily positioned at a retracted state before packaging. The fixing member can be inserted to lock the sliding member at a predetermined position, enabling compact packaging while maintaining the ability to adjust height during use
2Volume of stationary object
If conventional stroke fixing devices are used, then the packaging size is minimized, but the device complexity increases
Solution Approach 1:
The invention extracts the essential function of stroke fixing from complex conventional devices and implements it through a simplified mechanism. The fixing member is designed as a simple insertable component that engages with a positioning hole in the sliding member, eliminating the need for complex multi-component fixing devices while achieving the same stroke fixation function
3Ease of operation
If the lift stand is pre-oriented at maximum reach, then height adjustment is ready, but the lift stand yields under display weight during assembly
Solution Approach 1:
The lift stand allows preliminary assembly in a retracted state where the sliding member is fixed at a low position using the fixing member. This preliminary positioning provides stability during the assembly process and prevents yielding under display weight, while still allowing height adjustment to be performed later by removing the fixing member and sliding the member to the desired position
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
The design enables compact packaging, cost savings, and reduced assembly time while maintaining stability and ease of use by utilizing fewer components and less complex assembly processes.
Implementation Method 1
The elastic member is connected between the support structure and the sliding member, in providing a restoring force that enables the sliding member to move slidably against the support structure

AI summary
A positionable lift stand includes a support structure defining a first positioning hole, a sliding member slidably engaged with the support structure and defines a second positioning hole, an elastic member, and a fixing member. The elastic member is connected between the support structure and the sliding member, while provides a restoring force enabling the sliding member to move against the support structure. The fixing member passes through the first positioning hole of the support structure and the second positioning hole of the sliding member. By utilizing the fixing member and various positioning holes associated with the lift stand, the lift stand can be fixedly held to occupy the least amount of space for packaging or storing purpose. Such attribute is achieved by using fewer parts and processing steps, which means fewer parts need to be manufactured, more cost savings, and less assembling time.
