Leaf Spring Stand Leg for Thin Profile Computing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer device stands increase the thickness of computing devices when used to support displays or touchscreens in inclined orientations, compromising the device's thin profile and requiring complex hinges that consume space.
Innovation Solution
Incorporating a recessed leaf spring mechanism within the device's back cover that pivotally supports a stand leg, allowing the device to be oriented inclinedly without increasing thickness, and automatically retracts when not in use to maintain a thin profile and prevent damage during storage or transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional hinge mechanism is used to support the display in an inclined orientation, then the display can be positioned at various angles, but the thickness of the device increases and the profile becomes bulky
Solution Approach 1:
The patent extracts the hinge mechanism from the main device body and relocates it to a separate, removable stand component. This allows the display to achieve inclined positioning capability while the main device body remains thin and compact. The hinge function is taken out and embodied in the stand that can be attached only when needed.
Solution Approach 2:
The stand mechanism nests within the device ecosystem - the stand contains the hinge mechanism and can be stored or removed when not in use. The hinge foot pivots within a confined space, and the entire stand assembly can be detached, allowing the device to maintain its thin profile while gaining inclined display capability when required.
2Adaptability or versatility
If a complex hinge mechanism is incorporated into the device, then inclined display support is achieved, but the device structure becomes more complicated and space-consuming
Solution Approach 1:
The complex hinge mechanism is extracted from the main device and placed in a separate stand. This simplifies the main device structure while preserving the inclined display capability in the removable stand component.
Solution Approach 2:
The hinge mechanism includes a self-latching feature that automatically locks the stand at the desired angle without requiring complex control systems. The spring-loaded hinge foot self-adjusts and maintains position, reducing the need for additional motors, sensors, or control circuitry.
3Ease of operation
If the stand is extended for use, then inclined display positioning is enabled, but the device is vulnerable to damage during storage or transport
Solution Approach 1:
The stand is designed as a dynamic, movable component that can be extended when needed and retracted or removed when not in use. The hinge mechanism allows smooth transition between extended and retracted positions, enabling the device to adapt its configuration based on usage requirements while protecting vulnerable parts during storage.
Solution Approach 2:
The stand includes a latching mechanism that automatically secures the hinge foot in position when extended, and can be easily locked in a retracted or folded position for storage. This preliminary positioning action protects the extended stand from accidental damage during transport by ensuring it is properly secured in its storage configuration.
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 solution enables computing devices to be supported in various inclined orientations without adding thickness, reducing the need for complex hinges and protecting the device during storage by automatically retracting the stand, thus maintaining a slim profile and enhancing usability.
Implementation Method 1
a support mechanism pivotally supporting a support stand leg relative to the back cover, the support mechanism resiliently urging the support stand leg from an extended position towards a retracted position

AI summary
A support stand leg is pivotally supported by a leaf spring relative to a back cover of a computer device or a computer device case. The support stand leg is pivotal between a retracted position against the back cover and an extended position. The leaf spring urges the support stand leg towards the retracted position.
