Variable-Density Mesh Housing for Device Center-of-Mass Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices, such as digital styluses and wearables, often have unbalanced centers of mass due to the distribution of electronic components, leading to discomfort and instability, and lack a component that can effectively balance and ventilate while maintaining aesthetics.
Innovation Solution
The implementation of a mesh structure with a varying density profile, where the density transitions from higher to lower along the length, serving as a housing or component that balances the device by shifting the center of mass and also functions as a ventilation structure, potentially adding counterbalancing weight without additional bulk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electronic components are concentrated in one area of the device, then the device structure is simplified, but the center of mass becomes unbalanced causing discomfort and instability
Solution Approach 1:
The mesh structure implements local quality by varying the density of mesh elements in different regions. The first portion of the housing has a first mesh density while the second portion has a second mesh density, creating localized density variations that shift the center of mass to achieve balance without adding separate counterweight components.
Solution Approach 2:
The patent applies parameter changes by modifying the mesh density parameter across different portions of the housing. By changing the density parameter of the mesh structure from uniform to non-uniform distribution, the center of mass position is adjusted to achieve balance, resolving the contradiction between structural simplicity and balance stability.
2Temperature
If a mesh structure is used for ventilation, then airflow is improved, but the structural strength and center of mass control are compromised
Solution Approach 1:
The mesh structure applies local quality by assigning different mesh densities to different portions of the housing. The first portion has a higher mesh density for ventilation while the second portion has a lower mesh density for counterbalancing, allowing both ventilation and center of mass control to be achieved simultaneously within the same structural element.
Solution Approach 2:
The mesh housing structure serves multiple functions: it provides structural enclosure, enables ventilation through its open mesh design, and controls the center of mass through non-uniform mesh density distribution. This multi-functionality resolves the contradiction between ventilation performance and center of mass stability.
3Stability of the object's composition
If counterbalancing weight is added to balance the device, then center of mass is corrected, but the device bulk and weight increase
Solution Approach 1:
Instead of adding uniform counterbalancing weight, the patent uses local quality by concentrating higher mesh density in specific portions of the housing. This creates localized mass distribution that shifts the center of mass to the desired position without increasing the overall device weight, as the counterbalancing is achieved through redistribution rather than addition of mass.
Solution Approach 2:
The mesh housing acts as a composite structure where the varying mesh density creates different effective material densities in different regions. This composite approach allows the housing to serve both structural and counterbalancing functions without requiring separate counterweight materials, thereby avoiding additional weight.
