Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tablet computers and their docking stations face instability due to the position of the center of gravity, and existing solutions either increase weight, limit tilt angle adjustment, or cause discomfort when placed on a user's thigh.
Innovation Solution
A hinge module with a linking assembly and axle set that allows for the free adjustment of tilt angles, using a push and pull mechanism with a planetary gear transmission assembly to synchronize the motion of components, enabling independent tilt angle adjustment between the docking station and the electronic device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the weight of the docking station is increased to solve the instability problem caused by center of gravity position, then the stability is improved, but the lightweight advantage of the tablet PC and docking station is lost
Solution Approach 1:
The patent applies the counterweight principle by designing a foot stand that extends from the docking station to provide opposing weight compensation. The foot stand acts as a counterbalancing element that offsets the instability caused by the tablet's center of gravity position, allowing the docking station to maintain stability without increasing its overall weight.
Solution Approach 2:
The patent implements dynamics by making the foot stand adjustable through a hinge mechanism with multiple motion components. The foot stand can rotate and adjust its angle dynamically, allowing users to optimize the counterbalancing effect for different tablet positions and usage scenarios, thereby maintaining stability without fixed weight addition.
2Stability of the object's composition
If a supporting structure is designed to solve the instability problem, then the stability is improved, but the tilt angle adjustment freedom is lost
Solution Approach 1:
The patent employs dynamics by designing the foot stand with a hinge mechanism comprising multiple motion components that can rotate relative to each other. This dynamic structure allows the foot stand to adjust its angle freely, enabling the supporting structure to adapt to various tilt angles while maintaining stability, thus resolving the contradiction between stability and adjustability.
3Device complexity
If a foot stand is designed with limited support area at the back of the tablet PC, then the structure is simplified, but discomfort is caused when placed on the user's thigh
Solution Approach 1:
The patent applies dynamics by designing the foot stand as an adjustable structure rather than a fixed one. The foot stand can rotate and change its angle through the hinge mechanism, allowing users to optimize both the contact area with the thigh and the support characteristics, thereby reducing discomfort while maintaining relatively simple structure.
4Device complexity
If the foot stand location is fixed at the back of the tablet PC, then the design is simplified, but the tilt angle is limited
Solution Approach 1:
The patent implements dynamics by creating a movable foot stand connected through a hinge mechanism with multiple motion components. The foot stand can rotate and adjust its position dynamically, enabling a wide range of tilt angles while the overall design remains relatively simple due to the modular hinge structure.
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 hinge module provides stable and adjustable tilt angles for the electronic device, preventing discomfort when placed on the user's thigh and maintaining the lightweight advantage of the tablet PC.
Implementation Method 1
The transmission assembly is connected between the first axle and the second axle. When the second motion component rotates relative to the first motion component with a first angular velocity from a first operation state toward a second operation state, the second motion component props against the linking component by the push portion, such that the linking component drives the third motion component to synchronously rotate relative to the first motion component with a second angular velocity by the axle set.
