Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer brackets cannot automatically rotate or adjust their angle, making it inconvenient for individuals with mobility issues or disabilities to use them without external assistance.
Innovation Solution
A computer bracket with a first driving assembly, including a turbine self-locking motor, that allows the load-bearing part to rotate relative to the support part, and a second driving assembly that adjusts the connection assembly around a lower mounting end, enabling tilt and height adjustments through a parallelogram hinge structure and reduction motor system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a damping shaft with larger damping coefficient is used to support the computer mass, then the bracket can maintain stability, but the force required to operate the bracket increases
Solution Approach 1:
The patent replaces the traditional mechanical damping shaft system with an electric motor-driven rotating mechanism. The motor assembly includes a motor, transmission mechanism, and rotating connection between the support leg and base, eliminating the need for high-damping mechanical shafts. This substitution reduces the force required to adjust the bracket while maintaining stability through controlled motor operation.
Solution Approach 2:
The bracket incorporates a sensor assembly that automatically detects the presence and weight of a computer, then triggers the motor assembly to automatically adjust the support leg's rotation angle to an optimal position. This self-service mechanism eliminates the need for manual force application by the user, allowing individuals with mobility issues to operate the bracket independently.
2Device complexity
If the bracket structure is simplified without automatic rotation capability, then the device complexity is reduced, but the ease of operation for elderly or disabled persons deteriorates
Solution Approach 1:
The bracket incorporates a sensor assembly that automatically detects the presence and weight of a computer, then triggers the motor assembly to automatically adjust the support leg's rotation angle to an optimal position. This self-service mechanism eliminates the need for manual force application by the user, allowing individuals with mobility issues to operate the bracket independently.
Solution Approach 2:
The sensor assembly continuously monitors the bracket's state and the computer's placement, providing feedback to the control system. Based on this feedback, the motor assembly automatically adjusts the support leg angle to maintain optimal positioning. This closed-loop feedback system enables automatic adaptation without requiring complex manual intervention from the user.
3Reliability
If the load-bearing part is made heavier to support the computer, then the carrying capacity is improved, but the weight of the moving object increases
Solution Approach 1:
The patent transforms the static load-bearing structure into a dynamic system where the support leg can rotate relative to the base through a motor-driven mechanism. The load-bearing part includes a rotating connection that allows the support leg to adjust its angle automatically. This dynamic capability enables the bracket to adapt its configuration to support different computer weights and sizes without requiring a consistently heavy structure, as the motor provides the necessary force compensation.
