Pivotable Cover Bracket for Portable Device Ergonomic Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience fatigue when using portable electronic devices, such as smartphones or tablet computers, due to the need to hold them for extended periods or place them on a table, which can lead to discomfort during prolonged screen viewing.
Innovation Solution
A support unit comprising a cover, a positioning unit, and a bracket that pivots relative to the device's housing, allowing the device to be securely positioned on a table with adjustable viewing angles, maintaining a consistent appearance when retracted and expanding for support when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the portable electronic device is placed on a table or held for extended periods, then the device can be used for prolonged viewing, but user fatigue and discomfort occur
Solution Approach 1:
The support unit acts as an intermediary between the portable electronic device and the table surface. It provides an ergonomic interface that distributes the device weight and positions the screen at an optimal viewing angle, eliminating direct contact between the user's hand/arm and the device while preventing fatigue
2Ease of operation
If the support unit is expanded out of the housing, then ergonomic support is provided, but the device structure becomes more complex
Solution Approach 1:
The support unit is nested within the housing of the portable electronic device when not in use. The cover, bracket, and positioning unit are all contained within the device's form factor, allowing the device to maintain a compact appearance while providing ergonomic support when the support unit is deployed
Solution Approach 2:
The support unit transitions from a static, retracted state to a dynamic, deployed state. The cover can pivot outward, and the bracket can adjust to different angles, providing adaptive ergonomic support while maintaining a simple compact form when not in use
3Adaptability or versatility
If the cover is pivotably connected and expanded out, then adjustable viewing angles are achieved, but the mechanism complexity increases
Solution Approach 1:
The cover is pivotably connected to the housing, allowing it to rotate and adjust to different viewing angles. This dynamic mechanism provides versatility in positioning the device at ergonomic angles while maintaining a relatively simple hinge-based connection rather than complex mechanical systems
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 support unit provides ergonomic support for portable electronic devices, reducing user fatigue by allowing stable placement on a table with adjustable angles, enhancing user convenience and comfort during extended use.
Implementation Method 1
The cover is pivotably connected to a housing of the portable electronic device
Implementation Method 2
the first end of the bracket is engaged with one of the limiting recesses of the positioning unit to fix the expansion angle of the cover relative to the housing

AI summary
A support unit comprising a cover, a positioning unit and a bracket is provided. The cover is pivotably connected to a housing of the portable electronic device and can be received in the housing. The positioning unit is fixed to the housing and includes a plurality of limiting recesses. The bracket includes a first end and a second end that opposite. The first end is connected to the positioning unit, and the second end is pivotably connected to the cover. When the cover is expanded out of the housing, the first end of the bracket is driven by the cover to move relative to the positioning unit, and then the first end of the bracket is engaged with a limiting recess of the positioning unit to fix the expansion angle of the cover relative to the housing. A portable electronic device including the support unit is also provided.
