Retractable Battery Cover and Latch for Travel Bags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current travel bags with removable batteries face challenges in protecting the battery from moisture and dust, and the adjustable height trolley handles have limited adjustability, not accommodating individual user preferences.
Innovation Solution
The introduction of a retractable hingeless plastic cover for the battery opening and an adjustable height trolley handle with multiple fixation points along its telescoping height, allowing users to customize the handle height to their preference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable battery is installed in the travel bag, then the convenience of external charging is improved, but the risk of moisture and dust ingress to the battery compartment increases
Solution Approach 1:
A retractable cover is pre-positioned to automatically seal the battery opening when the battery is removed, preventing moisture and dust ingress before the compartment is exposed to the environment
Solution Approach 2:
A latch mechanism acts as an intermediary between the battery and the compartment, securing the battery in place while maintaining a sealed environment through coordination with the retractable cover
2Reliability
If a latch system is added to secure the battery, then the reliability of battery retention is improved, but the device complexity increases
Solution Approach 1:
The latch mechanism is merged with the retractable cover assembly, where the cover and latch work as an integrated unit to secure the battery, reducing the number of separate components and simplifying the overall structure
Solution Approach 2:
The latch system is designed to automatically engage and disengage based on the presence and removal of the battery, eliminating the need for manual operation and reducing user interaction complexity
3Adaptability or versatility
If telescoping trolley handles are made adjustable to multiple fixed positions, then the adaptability to different user heights is improved, but the device complexity increases
Solution Approach 1:
The handle shaft is segmented into multiple sections with predetermined fixation points, allowing the handle to be adjusted to different heights while maintaining structural integrity through modular construction
Solution Approach 2:
The handle incorporates a dynamic fixation mechanism that allows smooth transitions between fixed positions, enabling the user to adjust the handle height effortlessly while maintaining stability at each position
