Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable computer devices designed to be worn on the finger face challenges with battery weight distribution, leading to a higher tendency to slip and suboptimal space utilization due to limited battery curvature.
Innovation Solution
The use of multiple smaller, non-curved battery modules distributed around the circumference of a ring-shaped computer device, allowing for improved weight distribution and increased packing density within the device.

Engineering Contradiction Analysis
1Use of energy by moving object
If a single curved battery is used to fit the ring-shaped device, then the device can be powered, but the battery weight causes the centre of gravity to shift outside the axis of symmetry, increasing the tendency to slip
Solution Approach 1:
The single battery is divided into multiple battery modules (at least two) that are distributed around the circumference of the ring-shaped device. This segmentation allows the weight to be distributed more evenly, keeping the centre of gravity on the axis of symmetry and reducing the tendency to slip, while still providing sufficient power through the combined capacity of multiple modules.
2Volume of stationary object
If the battery is curved to match the ring shape, then space utilization improves, but the battery radius of curvature must be small which limits battery performance and functionality
Solution Approach 1:
Instead of using one large curved battery, the device employs multiple smaller battery modules that can be distributed around the ring. Each module can have a larger radius of curvature (improving functionality) while the collective arrangement maintains optimal space utilization through distributed packing along the circumferential path.
Solution Approach 2:
The battery configuration transitions from a single curved structure to a distributed arrangement along the circumferential dimension. By spreading multiple modules around the circumference rather than concentrating them in a single curved pack, the system achieves both good space utilization and maintained battery performance.
3Ease of operation
If the battery dimensions are reduced to fit the curved device shape, then the device can be worn comfortably, but the total battery capacity and performance are limited
Solution Approach 1:
The battery system is segmented into multiple modules distributed around the ring circumference. This allows each module to be small enough to maintain wearing comfort and balanced mass distribution, while the combined capacity of all modules provides sufficient overall power performance.
Solution Approach 2:
Multiple battery modules are electrically connected to function as a single integrated power source. The combined capacity of the distributed modules achieves the necessary total energy storage and power output while each individual module remains small enough to maintain device balance and wearing comfort.
