Spring-Locked Diagnostic Computer Stand for Adjustable Viewing Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diagnostic computers lack a suitable stand for supporting and positioning the device, necessitating manual handling or placement on surfaces during vehicle maintenance, which is inconvenient.
Innovation Solution
An adjustable stand with first and second clutches allows for rotation and fixation, utilizing springs to maintain a locking or unlocking position based on external force application, enabling adjustable angles between the stand and electronic device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no stand is provided for the diagnostic computer, then the device structure remains simple, but the device cannot be properly supported and positioned during vehicle maintenance
Solution Approach 1:
The stand is designed with dynamic adjustment capability through the clutch mechanism, allowing it to transition between locked and unlocked states. This enables the stand to be fixed during use for stability but adjustable when needed, resolving the contradiction between providing support functionality and maintaining structural simplicity.
Solution Approach 2:
The spring-loaded clutch mechanism automatically engages and disengages based on the stand's position and applied force. When the stand is tilted beyond a certain angle, the spring releases the clutch to lock the position; when force is applied within the normal range, the clutch remains engaged. This self-regulating mechanism provides support functionality without requiring complex external control systems.
2Ease of operation
If the stand is made fixed relative to the electronic device, then the structure is simple, but the viewing angle cannot be adjusted for optimal positioning
Solution Approach 1:
The clutch mechanism enables dynamic adjustment of the stand angle by transitioning between locked and unlocked states. Users can tilt the stand to adjust the angle, which automatically engages the clutch to lock at the desired position. This provides angle adjustability without requiring complex motors or controlled mechanisms.
Solution Approach 2:
The adjustment mechanism is segmented into discrete locking positions through the toothed clutch engagement. The stand can be positioned at multiple fixed angles corresponding to different clutch tooth engagements, providing adjustable positioning while maintaining mechanical simplicity through discrete rather than continuous adjustment.
3Stability of the object's composition
If the stand allows continuous pivoting, then the angle is highly adjustable, but the stand cannot maintain a stable locked position
Solution Approach 1:
The clutch mechanism creates a dynamic system where the stand transitions from a locked stable state to an unlocked movable state and back to a locked stable state. This allows the stand to maintain stability at selected angles while still providing the capability for adjustment, resolving the contradiction between locking stability and angle adaptability.
Solution Approach 2:
The spring mechanism provides beforehand cushioning by storing energy during the adjustment process and releasing it to ensure positive engagement of the clutch teeth. This pre-loaded spring ensures that when the clutch engages, the stand is firmly locked into position, providing stable locking while maintaining the ability to adjust to different angles.

Function Achieved in This Case
Enables convenient and adjustable positioning of the diagnostic computer, allowing users to set desired angles for optimal viewing and support, enhancing user experience during maintenance.
Implementation Method 1
A pair of springs are respectively located between the electronic device and the stand. When no external force applied, each pivot end is pulled by the spring and toward the first clutch to engage the second clutch with the first clutch
Implementation Method 2
The first clutches and the second clutches are annular and tooth-shaped, each encircling an outer periphery of the first pivot portion and the second pivot portion, respectively

AI summary
An assembly of an electronic device and a stand includes an electronic device, a stand and two springs. The electronic device includes two first clutches located on both sides of the electronic device. The stand includes two pivot ends which are symmetrically pivoted to the both sides of the electronic device. Each pivot end includes a second clutch formed to an inside thereof and engaged with the first clutch of the electronic device to form a locking position and an unlocking position. The springs are respectively located between the electronic device and the stand. When no external force applied, each pivot end engaged with the first clutch corresponding thereto to form a locking position. When each pivot end is pulled in a direction away from the first clutch, the second clutch is disengaged from the first clutch to form an unlocking position, and the stand is pivotable relative to the electronic device.
