Rotating Holder Structure for Damage-Free Extension Unit Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with detachable extension units, such as hard disk drive packs, risk damage during detachment due to excessive force application, leading to potential damage to both the extension unit and the main device body.
Innovation Solution
An electronic device design featuring a rotatable holding member with a restricting part within the extension slot, which supports one lateral surface of the extension unit and restricts rotation at a predetermined angle, preventing excessive force application during detachment.

Engineering Contradiction Analysis
1Ease of operation
If the extension unit is detached by applying force directly without rotation restriction, then the detachment operation is simple and quick, but the extension unit or device main body may be damaged due to excessive force
Solution Approach 1:
The restricting part is designed to preemptively prevent excessive rotation of the holding member before damage can occur. By limiting the rotation angle to a predetermined safe range, the system applies counter-action to the user's detachment force, blocking any rotational movement that would exceed the safe threshold and potentially cause damage to the extension unit or device main body.
Solution Approach 2:
The holding member acts as an intermediary mechanism between the user's detachment action and the extension unit. It provides a controlled rotation interface that mediates the force application, allowing the extension unit to be removed safely through restricted angular movement rather than direct linear pulling, thereby preventing harmful forces from being transmitted to vulnerable components.
2Ease of operation
If the holding member can rotate freely without restriction, then the extension unit can be easily maneuvered during detachment, but the lateral surface of the extension unit may be exposed at an angle that allows excessive force application
Solution Approach 1:
The restricting part preemptively counteracts the tendency of the holding member to rotate beyond the safe angle. By providing mechanical blocking at the predetermined rotation limit, it prevents the holding member from reaching positions where excessive force could be applied to the extension unit, thereby maintaining structural integrity while still allowing controlled maneuverability within the safe angular range.

AI summary
An electronic device in which a holding member for holding an external instrument is arranged rotatably on a housing section, and a restricting part for restricting, at a predetermined angle, rotation angle of the holding member is formed on an inner wall of the housing section. The holding member makes contact with a front side surface engaged with a connector of the external instrument. The restricting part restricts rotation of the holding member whose back surface facing the front side surface is exposed from the housing section. When holding member includes a guiding part that guides the external instrument in a direction that detaches it from the housing section when the holding member is further rotated beyond the restriction by the restricting part, the external instrument can be detached from the housing section when the rotation is equal to or larger than a restriction angle defined by the restricting part.
