Portable Energy Accumulator Housing With Side Opening and Dual Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional accommodation devices face reduced portability due to the placement of the opening at a corner, limiting the ability to provide handles at that location.
Innovation Solution
The accommodation device is designed with an opening on a side surface, allowing for handles on opposite sides to facilitate easier handling and portability, while maintaining a polyhedral shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the opening is disposed at a corner portion of the housing, then the accommodation unit can be compactly arranged, but the handle cannot be provided at this corner portion, resulting in reduced portability
Solution Approach 1:
The patent transitions from a single corner opening to multiple openings distributed across different surfaces of the polyhedral housing. By adding openings on multiple faces and corresponding handles at different locations, the design moves from a constrained single-point access to a multi-dimensional access system, enabling both compact arrangement and improved portability through multiple handling points
2Device complexity
If a single opening is provided at one location, then the housing structure can be simplified, but the user cannot easily hold and transport the device
Solution Approach 1:
The polyhedral housing with multiple openings and handles serves multiple functions simultaneously: it maintains structural simplicity through its geometric form while providing multiple access points for different operations (insertion, removal, carrying). Each opening-handle pair acts as a universal interface that can be used regardless of the device's orientation or the user's position

AI summary
An accommodation device includes a housing including six substantially quadrangular surfaces facing mutually different directions, the housing being provided in a substantially polyhedral shape, and an accommodation unit provided inside the housing, the accommodation unit accommodating a portable energy accumulator. An opening is provided in the accommodation unit to enable the portable energy accumulator to be inserted and removed, the opening is provided at a position corresponding to a first surface being one of the six surfaces. The first surface includes a first side and a second side, which are parallel to one another. A, first handle is provided at the first side on the housing and a second handle is provided at the second side on the housing.
