Movable Carrying Handles for Stable Access to Electrical Cases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical devices with fixed handle positions relative to the case body are inconvenient for users, as they may hinder stable carrying or access to the housing space.
Innovation Solution
The handles are designed to be movable relative to the case body, allowing them to change positions between upper and lower positions, thereby adjusting the center of gravity and minimizing interference with the housing space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle position is fixed relative to the case body, then the device structure is simple, but the user convenience deteriorates because the handle may hinder access to the housing space
Solution Approach 1:
The handle is designed to be movable relative to the case body along the longitudinal direction, allowing it to switch between a first position (retracted) and a second position (extended). This dynamic configuration enables the handle to avoid obstructing access to the housing space when retracted, while providing ergonomic gripping when extended, thus resolving the contradiction between user convenience and structural simplicity.
2Stability of the object's composition
If the handle grip is positioned high relative to the case body, then the user can stably carry the device, but the grip stands in the way for removing/putting objects from/into the housing space
Solution Approach 1:
The handle's ability to move between retracted and extended positions along the longitudinal direction allows the grip to be positioned high (in the extended position) for stable carrying, while being movable to a retracted position when access to the housing space is needed, thus eliminating the obstruction problem.
3Ease of operation
If the handle is movable relative to the case body, then the user convenience is improved, but the device complexity increases
Solution Approach 1:
The handle is configured to be movable along the longitudinal direction of the case body, providing positioning flexibility for user convenience. The movement mechanism appears to be a simple sliding or telescoping structure that extends the handle between two positions without requiring complex mechanical systems, thus balancing functionality with structural simplicity.

AI summary
An electrical device may include a case body, a battery receptacle configured to have a battery pack attached thereto, an external terminal configured to be electrically connected to the battery pack via the battery receptacle, a left handle disposed on a left surface of the case body and comprising a left grip configured to be grasped by a user, and a right handle disposed on a right surface of the case body and comprising a right grip configured to be grasped by the user. The left handle may be configured to be movable relative to the case body between a left lower position and a left upper position. The right handle may be configured to be movable relative to the case body between a right lower position and a right upper position.
