Sliding Lever Mechanism for Notebook Click Pad Key Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch pads on notebook computers can inadvertently activate key functions during browsing, causing interruptions due to the lack of control over the activation of key functions while using touch functions.
Innovation Solution
A key control device comprising a frame and a sliding lever, where the frame supports the click pad and the sliding lever, with positioning parts and locking parts, allows users to control the activation or shutdown of the key functions by sliding the lever, preventing false activation of key functions during touch operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the click pad has both touch functions and key functions, then the functionality is enhanced, but the risk of false activation increases
Solution Approach 1:
The patent applies the dynamics principle by making the key function activation state changeable through a sliding lever mechanism. The lever can be positioned to enable or disable the key functions, allowing the system to dynamically adapt its behavior based on user needs. This resolves the contradiction by providing a control mechanism that prevents false activation while preserving the enhanced functionality when needed.
2Speed
If the key functions are always active, then the responsiveness is improved, but the interference with touch browsing increases
Solution Approach 1:
The patent applies the preliminary action principle by providing a control mechanism (sliding lever) that allows users to pre-configured the activation state of key functions before using the touch pad for browsing. Users can disable key functions in advance to prevent interference during browsing sessions, while maintaining the ability to enable them when needed for responsive input.
3Adaptability or versatility
If a control mechanism is added to manage key function activation, then the control flexibility is improved, but the device complexity increases
Solution Approach 1:
The patent applies the local quality principle by implementing a simple sliding lever mechanism with positioning parts and locking parts that are locally integrated into the click pad structure. Rather than adding a complex control system throughout the entire device, the control flexibility is achieved through a localized mechanism that only affects the key function activation state, thereby minimizing the increase in overall device complexity.

AI summary
The present disclosure relates to a key control device for click pad. The key control device is disposed below a click pad of a notebook computer, and comprises a frame and a sliding lever. The click pad is disposed at the frame. When a plurality of positioning parts of the sliding lever are interlocked with a plurality of locking parts of the frame, the frame and the click pad cannot have up-and-down movements and thus shutting down the key functions of the click pad. When the plurality of positioning parts of the sliding lever are not interlocked with the plurality of locking parts of the frame, the frame and the click pad can have up-and-down movements and thus activating the key functions of the click pad. Thereby, the key control device according to the present disclosure can control the activation or shutdown of the key functions of the click pad.
