Battery Holder Weight Distribution for Handheld Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld devices, such as computer mice, often have weight distribution issues due to varying hand sizes and wrist strengths among users, as well as different usage requirements, leading to a need for customizable weight distribution solutions.
Innovation Solution
A battery-operated computer mouse with a customizable weight distribution system, featuring a battery holder with multiple slots for different battery sizes, allowing users to adjust the weight distribution by selecting appropriate batteries, thereby accommodating various hand sizes, wrist strengths, and usage scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a handheld device is designed with fixed weight distribution, then the device structure is simple, but it cannot accommodate different user hand sizes and wrist strengths
Solution Approach 1:
The battery holder is divided into multiple slots (first battery slot and second battery slot) that can accommodate different battery sizes. This segmentation allows users to configure weight distribution by selecting which slots to fill, providing adaptability without requiring complex adjustable mechanisms.
Solution Approach 2:
The battery holder serves multiple functions: it provides power supply and simultaneously enables weight distribution adjustment. By designing slots that accept different battery sizes, the same structural component achieves both electrical and mechanical customization goals.
2Adaptability or versatility
If multiple batteries are added to adjust weight distribution, then weight customization is achieved, but the device complexity increases
Solution Approach 1:
The battery holder is designed to simultaneously provide power supply and enable weight distribution adjustment. By designing slots that accept different battery sizes, the same structural component achieves both electrical and mechanical customization goals without adding separate adjustment mechanisms.
Solution Approach 2:
Users can independently adjust weight distribution by selecting which battery slots to fill based on their needs. The system provides self-service functionality where the user's battery insertion choices directly determine the weight configuration without requiring complex control systems.
3Adaptability or versatility
If different battery sizes are accommodated, then weight distribution flexibility is improved, but manufacturing precision requirements increase
Solution Approach 1:
Different battery slots are designed with specific local qualities tailored to their intended battery sizes. The first slot is optimized for one battery type while the second slot is optimized for another, allowing each slot to have precise dimensions suited to its specific function rather than requiring all slots to meet the same precision standard.

AI summary
A battery-operated handheld device including a housing to enclose electrical components and a battery holder. The battery holder including a first battery slot and a second battery slot. The first and second battery slots being sized to hold batteries of different battery sizes. The second battery slot being alongside the first battery slot. The electrical components of the handheld device may be powered by either the first battery inserted into the first battery slot or the second battery inserted into the second battery slot. The battery holder may serve as an adjustable weight distribution mechanism to shift a centre of gravity of the handheld device between a first predetermined centre of gravity associated with the first battery inserted into the first battery slot and a second predetermined centre of gravity associated with the second battery inserted into the second battery slot.
