Solution Overview
Problem
Existing electronic devices face challenges in optimizing space utilization due to the use of square or cylindrical batteries, which require separate compartments, leading to inefficient space utilization and hindering the goal of thinning and lightening the device.
Innovation Solution
The design incorporates a battery with a main body portion, a protruding portion, and an avoidance portion that adapt to the functional components, allowing the battery to occupy remaining space efficiently and avoid interference, thereby enhancing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a separate battery compartment is set up for the battery, then the battery can be conveniently manufactured with square or cylindrical shapes, but space utilization is low
Solution Approach 1:
The battery is divided into multiple portions (first portion, second portion, third portion) with different shapes and functions. The first portion is square-shaped for compact fitting, the second portion is cylindrical for optimal electrochemical performance, and the third portion is an avoidance portion that segments the battery structure to accommodate functional components. This segmentation allows the battery to conform to the irregular available space while maintaining manufacturing feasibility.
Solution Approach 2:
The battery portions are nested within the housing space in a hierarchical manner. The first square portion is positioned in the lower region, the second cylindrical portion is arranged above it, and the third avoidance portion is integrated into the upper region. This nested arrangement allows smaller battery portions to fit within the contours defined by larger portions and the housing, maximizing space utilization.
2Volume of moving object
If the battery is designed to occupy all available space, then space utilization improves, but interference with functional components increases
Solution Approach 1:
Different portions of the battery are designed with different local qualities and shapes to suit specific spatial requirements. The first portion has a square cross-section optimized for the lower space, the second portion has a cylindrical shape optimized for the middle region, and the third portion has an avoidance shape specifically designed to accommodate functional components in the upper region. This local optimization allows the battery to fill space efficiently without causing interference.
Solution Approach 2:
Instead of designing the battery as a single solid mass and then cutting out spaces for functional components, the invention inverts the approach by proactively designing avoidance portions that protrude toward functional components. The third portion of the battery is specifically shaped with avoidance features that anticipate and accommodate the positions of functional components, thereby preventing interference rather than creating it.
3Weight of moving object
If the electronic device is made thinner and lighter, then portability improves, but space for battery and components becomes limited
Solution Approach 1:
The battery design transitions from traditional two-dimensional planar arrangements to a three-dimensional multi-port ion structure that utilizes vertical and diagonal spaces. The first, second, and third portions are arranged in different spatial dimensions and orientations, filling gaps and voids that would otherwise be wasted. This dimensional approach allows maximum battery capacity within a reduced overall device volume.
Solution Approach 2:
The invention changes the geometric parameters of the battery from conventional uniform shapes to a multi-port ion structure with varying dimensions. The first portion has different height and width parameters, the second portion has cylindrical parameters, and the third portion has avoidance parameters specifically tailored to the device's functional component layout. These parameter changes enable the battery to adapt to the constrained three-dimensional space of thin and light devices.
