Display Stand Latch Hinge Structure to Prevent Over-Folding Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD stands are prone to damage due to excessive force when adjusting angles or folding, as the metal hinge structure can pivot excessively and cause the stand to collapse, leading to potential damage to the display device.
Innovation Solution
A stand design featuring a housing with a latch and hinge structure that includes a positioning groove and a spring mechanism, allowing for adjustable angles without excessive pivoting, with a cushion body to absorb force and prevent damage, and a strengthening board for added stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stand is pressed to a position parallel to the backboard for packaging or moving, then the stand can be folded for convenient packaging or moving, but the stand is easily pivoted excessively and damaged due to excessive force exerted by the user
Solution Approach 1:
The latch mechanism is pre-configured to engage with the positioning groove before the stand is fully folded. When the user presses the stand toward the parallel position, the latch automatically detects and engages the positioning groove, preventing excessive pivoting before the folding action is complete. This preliminary engagement action protects the stand from damage while still allowing convenient folding.
Solution Approach 2:
The latch acts as an intermediary mechanism between the user's folding action and the hinge structure. It mediates the force transmission by engaging the positioning groove, thereby controlling the pivoting motion and preventing excessive force from reaching the hinge structure and causing damage.
2Adaptability or versatility
If the stand allows free pivoting for angle adjustment, then users can adjust the included angle as desired, but the stand may be completely folded inadvertently when excessive force is used
Solution Approach 1:
The system dynamically transitions between two states: during normal angle adjustment, the latch remains disengaged allowing free pivoting for adaptability; during folding or when excessive force is applied, the latch engages the positioning groove to provide stability and prevent inadvertent complete folding. This dynamic behavior resolves the contradiction between adjustability and stability.
Solution Approach 2:
The latch mechanism provides preliminary anti-action by being positioned to engage the positioning groove before excessive pivoting can occur. When the stand approaches the parallel position or experiences excessive force, the latch preemptively engages to counteract the harmful motion, preventing the stand from being completely folded inadvertently.
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 stand prevents damage by controlling the pivoting motion and absorbing excessive force, ensuring the display device remains stable during angle adjustments and movement, thereby preventing collapse and maintaining structural integrity.
Implementation Method 1
The fastening portion is selectively engaged with the positioning groove by releasing a spring force of a spring connected to the latch
Implementation Method 2
the fastening portion is disengaged from the positioning groove by compressing the spring connected to the latch

AI summary
A stand for a display device is provided and includes a housing having an accommodating groove, a hinge structure including a first board and two second boards, and a latch including an operation portion. The first board is fixed on a backboard of the display device and has a positioning groove. The two second boards are rotatably connected respectively to two ends of the first board and each is fixed on the housing. The latch is flexibly placed on the housing and is aligned with the first board. The operation portion is exposed through the accommodating groove. The fastening portion is selectively engaged with the positioning groove by releasing a spring force of a spring connected to the latch. When the operation portion is moved in a direction away from the first board, the fastening portion is disengaged from the positioning groove by compressing the spring.
