Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large battery devices face issues with force transmission stability due to long engagement lengths, leading to wobbling and potential damage, especially when engaging with standard-sized working devices.
Innovation Solution
A battery device with a transmission mechanism using overlapping connecting rods with obtuse angles and reinforcing ribs, along with elastic members, to ensure stable and rigid force transmission, allowing for a larger size battery to engage with standard devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the engagement portion of the switch and the locking structure is made long to satisfy the needs for long-distance transmission of motion, then the transmission distance is improved, but the stability of force transmission deteriorates due to wobbling and potential bending
Solution Approach 1:
The transmission mechanism is divided into multiple connecting rods (first connecting rod, second connecting rod, etc.) that work together to transmit force. This segmentation allows the system to achieve long transmission distance while maintaining stability, as each rod segment is shorter and less prone to wobbling than a single long arm would be.
Solution Approach 2:
The connecting rods are arranged in an overlapping configuration rather than a simple linear extension. This spatial arrangement in multiple dimensions allows the mechanism to achieve the required transmission distance while keeping each individual rod component compact and stable, avoiding the wobbling issues associated with long single-dimensional arms.
2Power
If the battery device is made larger to provide sufficient power, then the power output is improved, but the compatibility with standard working devices deteriorates due to engagement difficulties
Solution Approach 1:
The locking structure is designed as a separate, movable component that can extend and retract independently of the battery device body size. This segmentation allows large battery devices to engage with standard working devices by having the locking component adapt its position rather than requiring the entire device to be small.
Solution Approach 2:
The locking structure is designed to be movable rather than fixed, allowing it to dynamically adjust its position during engagement. This dynamic design enables compatibility with standard working devices regardless of the battery device's overall size, as the locking component can reach the necessary engagement points.
