Movable Locking Hole Housing for Selective Electronic Card Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fixed location of locking holes in notebook computer housings restricts the ability to accommodate electronic cards of different sizes, limiting flexibility in positioning.
Innovation Solution
A housing with a movable locking hole system, featuring a lever body that can pivot to align with either a first or second locking hole, allowing the same fastener to secure electronic cards of varying sizes by adjusting the position of the locking hole relative to the base plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed locking hole location is used in the housing, then the structure is simple and easy to manufacture, but the housing cannot position selectively electronic cards having different sizes
Solution Approach 1:
The locking hole is made movable instead of fixed. The movable element can be positioned at different locations along the base plate to align with locking holes of electronic cards of different sizes, enabling selective positioning while maintaining a relatively simple structure.
Solution Approach 2:
A single movable locking hole structure serves multiple positioning functions. By moving the locking hole to different locations, the same structure can accommodate electronic cards of various sizes, eliminating the need for multiple fixed locking holes for different card types.
2Adaptability or versatility
If multiple fixed locking holes are provided for different electronic card sizes, then positioning flexibility is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
Instead of providing multiple fixed locking holes during manufacturing, a single movable locking hole is implemented that can be dynamically repositioned. This reduces manufacturing complexity while maintaining the ability to accommodate different electronic card sizes through repositioning the movable element.
Solution Approach 2:
The locking hole function is separated from the base plate structure and implemented as a distinct movable element. This segmentation allows the locking hole to be independently positioned and adjusted, simplifying the overall housing structure while enabling accommodation of various card sizes.
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
Enhances flexibility in accommodating electronic cards of different sizes by allowing the locking hole to be positioned correctly for secure fastening, eliminating the need for preformed locking holes that restrict size variability.
Implementation Method 1
a first end portion connected pivotally to the base plate

AI summary
A housing is usable for positioning selectively a first electronic card having a first locking hole and a second electronic card having a second locking hole, and includes a base plate, a connector for mating with the selected one of the first and second electronic cards, and a movable element including a lever body that has an end portion connected pivotally to the base plate and a third locking hole opposite to the end portion. The lever body is operable to move the third locking hole between a first position, where the third locking hole is aligned with the first locking hole to cooperatively receive a fastener for fastening one of the first and second electronic cards, and a second position, where the third locking hole is aligned with the second locking hole to cooperatively receive the fastener for fastening the other one of the first and second electronic cards.
