Height-Adjustable Equipment Stand With Parallel Folding Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height-adjustable device stands for notebooks and monitors are either complex, visually disturbing, unstable, or require significant effort to adjust, often resulting in devices tilting or slipping during use, and fail to maintain a horizontal or defined inclined position effectively.
Innovation Solution
A device stand with collapsible supports that guide the support surface parallel to the base, using non-parallel articulation of support edges and incorporating cutouts to minimize space and ensure stability, allowing for quick height adjustments and secure locking at various positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pivotable support arms with clamping devices are used to attach to existing desk tops, then height adjustment is enabled, but the desk space behind the monitor and keyboard is moved and the structure is visually disturbing even when lowered
Solution Approach 1:
The support structure is divided into multiple scissor arm segments that can be independently adjusted and locked at different heights. This segmentation allows the support to be compact when lowered while providing multiple stable positions when raised, enabling height adjustment without occupying excessive desk space in the lowered state.
Solution Approach 2:
The scissor arms are designed to nest within each other when lowered, with each arm segment fitting into the previous segment. This nesting mechanism minimizes the space occupied by the support structure in its lowered state, allowing it to be virtually invisible on the desk surface while maintaining full height adjustment capability when needed.
2Adaptability or versatility
If long stable supporting arms are used to enable height adjustment, then height variation is achieved, but the keyboard cannot be lowered to within a few millimeters of desk level and the usual arm and hand position cannot be maintained
Solution Approach 1:
The scissor arm mechanism provides dynamic height adjustment with multiple lockable positions, allowing the keyboard to be positioned at any height from nearly desk level to a comfortable standing position. The incremental adjustment capability enables precise positioning to maintain proper ergonomics while achieving full height variation range.
Solution Approach 2:
The support structure incorporates adjustable parameters including height, inclination angle, and lateral positioning. By changing these parameters in controlled increments, the system can lower the keyboard to within millimeters of desk level while maintaining the user's natural arm and hand position through multi-position locking mechanisms.
3Adaptability or versatility
If scissor arm constructions are used for height adjustment, then height variation is achieved, but the ends of their scissor arms often slide noisily in a guide rail and easily jam when tilted
Solution Approach 1:
The traditional guide rail system with sliding scissor arm ends is replaced with a pin-and-hole locking mechanism. This substitution eliminates the sliding contact that causes noise and jamming, replacing it with discrete positioning points that provide reliable, quiet operation while maintaining full height variation capability.
Solution Approach 2:
The continuous sliding motion of scissor arms in guide rails is replaced with discrete positional parameters defined by pin locations in holes. This parameter change from continuous to discrete positioning eliminates the jamming issue while maintaining smooth operation, as each pinned position represents a stable equilibrium point.
4Productivity
If the support surface is raised quickly with collapsible supports, then height adjustment speed is improved, but the support surface may not maintain horizontal or defined inclined position and devices may slip down
Solution Approach 1:
The scissor arms are pre-configured with multiple pinned positions that define stable equilibrium points. When the support surface is raised quickly, the scissor arms automatically snap into these pre-defined positions, ensuring the support surface maintains the correct horizontal or inclined angle without slipping, while still enabling fast height adjustment.
Solution Approach 2:
The pinned scissor arm mechanism provides mechanical feedback through distinct tactile and auditory signals when reaching stable positions. This feedback ensures the support surface has settled into a stable configuration before use, confirming that devices will not slip down while maintaining quick adjustment capability through the snap-action mechanism.

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 solution provides a compact, stable, and user-friendly height-adjustable device stand that maintains devices in a horizontal or inclined position without slipping, minimizing space usage and allowing for easy operation in the usual arm position, even during height adjustments.
Implementation Method 1
The lower support halves 3, 5 and 7 of each support are connected to the base 1 in an articulated manner. The upper support halves 4, 6 and 8 of each support are also connected in an articulated manner to the supporting surface 2 at the support edges 4a, 6a and 8a.
Implementation Method 2
at least one support contains cutouts in this way that at least one other support part protrudes there into at least one height, wherein the support surface can be locked against lowering at at least one height.

AI summary
The invention relates to a fast height-adjustable equipment stand, particularly for a notebook or for a monitor with keyboard, which can be placed on a table and the support surface (2) of which can be raised or lowered so low that a keyboard situated on the support surface (2) can be operated without difficulty while sitting. To this end, at any height the equipment present thereon is held in a horizontal or defined oblique position such that the support surface (2) is guided by at least two folding brackets (3/4, 7/8), which cause a parallel guidance of the support surface (2) relative to the base surface (1) in that the edges (4a, 8a) thereof are fastened non-parallel to each other to the support surface (2) in an articulating manner, and that the support surface (2) can be locked in one or more heights to prevent accidental lowering.
