Detachable Container Lateral Cover for Secure Two-Handed Gripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Detachable containers with heavy weights are prone to accidental dropping during attachment or detachment due to incorrect operation, as existing designs lack effective mechanisms to prevent gripping only the outer operation units.
Innovation Solution
The detachable container features elastically deformable outer gripping units with engagement and inner gripping units, along with a cover that projects laterally to cover the gap between the side walls and the outer gripping unit, making it difficult to grip only the outer unit, thereby preventing accidental detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only outer gripping units are provided on the container body, then the ease of operation is improved, but the reliability deteriorates due to accidental dropping from wrong operation
Solution Approach 1:
The patent introduces an inner gripping unit as an intermediary element between the outer gripping unit and the container body. This inner gripping unit acts as a mediator that guides the user's fingers during gripping operation, preventing direct gripping of only the outer gripping unit which could cause accidental dropping. The inner gripping unit mediates the interaction between user and container to ensure proper two-handed gripping.
2Stability of the object's composition
If the container body is made heavy to ensure stability, then the stability is improved, but the ease of operation deteriorates due to difficulty in handling
Solution Approach 1:
The patent segments the gripping function into two separate units: an outer gripping unit attached to the container body and an inner gripping unit attached to the operation unit. This segmentation allows the heavy container body to remain stable while the operation units are designed for easy gripping. The weight stability is maintained in the container body, while the segmented gripping units facilitate easy handling.
3Ease of operation
If the outer gripping unit is made elastically deformable to improve ease of operation, then the ease of operation is improved, but the device complexity increases due to additional structural requirements
Solution Approach 1:
The patent employs a flexible outer gripping unit that is elastically deformable, allowing it to be compressed by finger pressure during gripping operations. This flexible structure provides ease of operation while maintaining relatively simple construction. The elastic deformability is achieved through material selection and geometric design rather than complex mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures secure gripping of both operation units, preventing accidental drops and facilitating safe attachment and detachment of the container, even when heavy, by making it difficult to grip only the outer unit.
Implementation Method 1
the outer gripping unit being elastically deformable via a gap between the outer gripping unit and the container body

AI summary
A detachable container includes: a container body; and operation units on both sides of the container body attaching and detaching the container body. Each operation unit includes an outer gripping unit at an outer side of a respective one of both side walls of the container body, an inner gripping unit at an inner side of the respective one of both side walls of the container body in the width direction in an attachment and detachment operation side surface of the container body, and a cover projecting in an eave shape laterally from a respective one of both sides of the attachment and detachment operation side surface of the container body in the width direction, the cover covering the gap between the respective one of both side walls of the container body and a projecting end of the outer gripping unit when viewed from the attachment and detachment operation side.
