Variable-Density Mesh Structure for Device Center-of-Mass Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices, such as computing devices, styluses, and wearables, face challenges in achieving a neutral center of mass and mimicking the feel of traditional writing instruments due to uneven distribution of electronic components, leading to discomfort and instability.
Innovation Solution
The implementation of a mesh structure with a varying density profile, where the density transitions from higher at one end to lower at the other, effectively counteracts the weight of electronic components, simulating the balance and feel of a traditional wooden pencil by strategically distributing interconnected material and interstitial spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic components are concentrated in one region of the device, then device functionality is improved, but center of mass balance deteriorates
Solution Approach 1:
The mesh structure implements local quality by varying the density of interconnected material at different locations along the device. Regions with higher electronic component concentration have higher mesh density (more interconnected material), while regions with lower electronic component concentration have lower mesh density. This spatially varying structure compensates for the uneven weight distribution of electronic components, achieving neutral center of mass balance while maintaining full device functionality.
2Stability of the object's composition
If mesh structure density is increased to improve balance, then center of mass control is improved, but device weight increases
Solution Approach 1:
Rather than uniformly increasing mesh structure density throughout the device, the invention applies local quality by strategically varying density only in specific regions. The mesh structure has higher density (more interconnected material) in regions that require additional weight for balance, and lower density (fewer interconnected material) in regions where additional weight is not needed. This localized approach achieves precise center of mass control while minimizing overall device weight.
3Strength
If mesh structure is made more dense, then structural strength is improved, but ventilation capability deteriorates
Solution Approach 1:
The mesh structure implements local quality by varying density based on functional requirements of different device regions. Regions requiring high structural strength (such as areas supporting electronic components or subject to mechanical stress) have higher mesh density with more interconnected material. Regions requiring ventilation (such as areas near heat-generating components) have lower mesh density with more open interstitial spaces. This spatially varying structure simultaneously optimizes both structural strength and ventilation capability.
