Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld tool storage devices lack efficient and compact designs for positioning operating elements relative to the axis of motion, leading to inconvenient access and energy supply challenges, especially in scenarios without a network power source.
Innovation Solution
A handheld tool storage device with a base body unit featuring a movably supported carrying case cover and base body, where the operating element and energy store interface are positioned at a minimum distance from the axis of motion, allowing for compact and accessible operation, and incorporating a rechargeable battery pack for network-independent energy supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operating element is positioned far from the axis of motion of the base body element, then the operating element has sufficient space for operation, but the device size increases and accessibility becomes inconvenient
Solution Approach 1:
The operating element is positioned in a direction perpendicular to the main extension of the base body element, utilizing the width dimension rather than extending the length. This allows the operating element to be accessible without increasing the main length of the device, effectively using dimensional space efficiently.
Solution Approach 2:
The base body element is designed to be movable relative to the housing, allowing the operating element to be positioned at an optimal location that accommodates both compact device size and ease of operation. The movability enables the operating element to access different spatial positions during device operation.
2Volume of moving object
If the device is designed for compact size, then portability is improved, but the positioning of operating elements and energy supply components becomes constrained
Solution Approach 1:
The operating element is positioned at a distance from the axis of motion measured perpendicular to the main extension direction, utilizing the width dimension of the device. This dimensional approach allows compact length while maintaining operational accessibility.
Solution Approach 2:
The device is segmented into a housing and a movable base body element, allowing independent optimization of each component. The operating element can be positioned on the movable element at an optimal location for accessibility, while the overall device maintains compact dimensions through this segmentation.
3Adaptability or versatility
If the device lacks network power source access, then portability and independence are improved, but energy supply capability is limited
Solution Approach 1:
The energy supply system is designed to perform multiple functions: it can operate independently using the rechargeable battery pack for portable applications, and it can also be connected to external power sources for recharging or extended operation. This multi-functionality resolves the contradiction between independence and energy supply capability.
Solution Approach 2:
The energy supply configuration is dynamic and adaptable - the device can switch between battery-powered independent operation and externally connected power supply mode. This dynamic capability allows the device to maintain both portability/independence and adequate energy supply capability depending on operational context.
