Foldable Bracket with Segmented Rod Assemblies for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet music brackets cannot be completely folded and stored, leading to inconvenience during packaging, transportation, and carrying due to the large space occupied by the sheet music placing plate.
Innovation Solution
A foldable bracket design that includes a leg bracket assembly, a pulling-rod assembly, and a supporting assembly. The supporting assembly can move between an unfolded state and a retracted state, allowing it to form a rod-shaped structure for storage, thereby enabling easy carrying and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the sheet music placing plate is made rigid and flat for stability, then the supporting function is improved, but the storage volume and portability deteriorate due to large space occupation
Solution Approach 1:
The sheet music placing plate is divided into multiple rod assemblies (first connecting rod assembly, second connecting rod assembly, third connecting rod assembly) that can be folded relative to each other. Each rod assembly consists of multiple rods connected by rotating shafts, allowing the plate to be segmented into collapsible sections that reduce storage volume while maintaining structural integrity when deployed.
Solution Approach 2:
The rod assemblies are designed to nest within each other when folded. The first, second, and third connecting rod assemblies can be stored inside or alongside the main bracket body, with each assembly containing rods that fit within the structural envelope of the others, minimizing the overall storage volume to a compact rod-shaped structure.
2Ease of operation
If the bracket is designed to be fully foldable for portability, then the ease of carrying is improved, but the structural complexity increases
Solution Approach 1:
The bracket employs dynamic folding mechanisms with rotating shafts that allow the rod assemblies to transition between extended and retracted states. The rotating shafts enable smooth angular movement between rods, creating a dynamic structure that adapts between transport and use configurations without requiring complex locking or latching systems.
Solution Approach 2:
The rod assemblies serve multiple functions: they form the structural framework of the sheet music placing plate, provide adjustable support angles, and act as the folding mechanism itself. The same rods that provide structural integrity when extended also serve as the collapsing elements during folding, eliminating the need for separate folding components and reducing overall structural complexity.

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 foldable bracket allows for compact storage and easy unfolding, making it convenient for users to carry and use, while also simplifying packaging and transportation for manufacturers.
Implementation Method 1
the main bracket being rotatably coupled to the pulling-rod assembly second end via a rotating shaft
Implementation Method 2
The torsion spring is sleeved on the torsion shaft. Torsion spring first end abuts against the pressing block, and the torsion spring second end abuts against the upper housing

AI summary
The foldable bracket includes a leg bracket assembly, a pulling-rod assembly, and a supporting assembly. The pulling-rod assembly has a pulling-rod assembly first end and a pulling-rod assembly second end that are opposite to each other. The leg bracket assembly is coupled to the pulling-rod assembly first end. The supporting assembly is foldably coupled to the pulling-rod assembly second end. The supporting assembly has an unfolded state and a retracted state. The supporting assembly includes at least a main bracket, a first connecting rod assembly, and a second connecting rod assembly. In the unfolded state, the first connecting rod assembly and the second connecting rod assembly are unfolded and form a supporting surface. In the retracted state, the first connecting rod assembly and the second connecting rod assembly are affixed with the main bracket, respectively, and form a rod-shaped structure.
