Detachable Laptop Touchpad Module With Hook-Lock Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laptop computers have fixed-structure designs that make maintenance and component replacement difficult, particularly for the touchpad module, requiring users to replace the entire device when the touchpad is damaged.
Innovation Solution
A detachable touchpad module design with a locking hook and locking hole configuration allows easy assembly and removal from the laptop's housing, using positioning pillars, abutting protrusions, and bidirectional locking hooks with pressing grippers for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the touchpad module is fixed inside the housing by screws or melting, then the structural stability is improved, but the ease of repair deteriorates
Solution Approach 1:
The patent divides the touchpad module into a separable component from the housing. The touchpad module includes a touchpad plate, touchpad component, and adhesive layer that can be detached as a unit, allowing repair without dismantling the entire housing structure.
Solution Approach 2:
The patent extracts the touchpad module as a removable component. The module is designed to be taken out from the housing through a specific opening, enabling easy replacement and repair while maintaining the integrity of the remaining device structure.
2Manufacturing precision
If the touchpad module is assembled to the internal surface of the housing from inside to outside, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-assembling the touchpad module with its adhesive layer and components before installing it to the housing. The module is prepared in advance as a complete unit, simplifying the final assembly process and reducing on-site complexity.
Solution Approach 2:
The patent designs the touchpad module as a universal component that can be installed and removed multiple times. The module serves both as a functional input device and as a replaceable repair component, reducing overall device complexity through standardization.
3Manufacturing precision
If other components are assembled into the housing in order before the touchpad module, then the manufacturing precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent inverts the traditional assembly sequence by allowing the touchpad module to be installed last rather than first. This reversal enables the module to be attached to the housing after other components are in place, simplifying replacement operations without compromising assembly precision.
Solution Approach 2:
The patent extracts the touchpad module installation step from the middle of the assembly process and positions it as a final, independent operation. The module can be taken out and installed separately, improving ease of operation while maintaining precise positioning through dedicated mounting features.

AI summary
A laptop computer with a detachable touchpad module includes a housing, a locking hook, and a touchpad module. The housing has a first surface and a second surface opposite to each other. The first surface is an external surface of the housing, and the second surface is an internal surface of the housing. The locking hook is freely pivoted to the housing and located at the second surface. The touchpad module has a locking hole. When the touchpad module is assembled to the first surface, the locking hole penetrates the housing and is protruded out of the second surface, and the locking hook is locked with the locking hole.
