Hinge Temporary Fixation for Laptop Assembly Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook personal computers require accurate alignment and positioning of screws to fix the hinge to the housing, which increases assembly time and reduces efficiency.
Innovation Solution
The electronic apparatus employs a temporary fixation mechanism using housing engaging portions and hinge engaging portions to securely hold the first fixing member in place, allowing for easy alignment and stable positioning before screwing, thereby simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix the first fixing member to the housing, then the display panel can rotatably move stably with respect to the housing, but it increases the time required to position the housing and first fixing member, thus reducing assembly efficiency
Solution Approach 1:
The patent applies preliminary action by providing positioning protrusions on the housing and corresponding positioning grooves on the first fixing member before screw fixation. These positioning features are pre-formed on the components, allowing them to automatically align and engage during assembly. This preliminary positioning action eliminates the need for manual alignment and positioning adjustments that would otherwise be required before screwing, thereby reducing assembly time while maintaining the stability needed for reliable screw fixation and subsequent rotatable movement of the display panel.
2Manufacturing precision
If accurate association of housing position with first fixing member position is required, then the hinge can be securely fixed, but the efficiency of assembly is reduced
Solution Approach 1:
The patent applies self-service through self-aligning positioning protrusions and grooves that automatically guide the first fixing member into the correct position on the housing during assembly. The complementary geometries of these features cause them to mate precisely without requiring external alignment tools or manual positioning adjustments. This self-aligning mechanism ensures accurate association of positions while eliminating time-consuming positioning operations, thereby maintaining manufacturing precision while improving assembly efficiency.

AI summary
According to one embodiment, an electronic apparatus includes a main body, a display panel, and a hinge. The main body includes a housing having a main wall and a first engaging portion placed inside the housing. A space portion is created between the first engaging portion and a plane defined by an inner surface of the main wall. The hinge includes a first fixing member fixed to the housing, a second fixing member fixed to the display panel, and a connection member which rotatably connects the second fixing member to the first fixing member. The first fixing member has a base located opposite the main wall with respect to the first engaging portion and a second engaging portion which is to be inserted into the space portion to engage with the first engaging portion.
