Click Pad Key Control Device with Dual Driving Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch pads on notebook computers can inadvertently activate key functions during browsing, causing interruptions due to accidental presses, as they only offer touch functions for cursor movement and window control, lacking a mechanism to prevent false activation of key functions.
Innovation Solution
A key control device comprising a first and second driving member, a first and second connecting rod, and a pivot part, which allows for the activation and shutdown of key functions by pressing specific areas below the click pad, ensuring the key functions are not activated falsely during touch operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the click pad provides both touch functions and key functions, then the input capability is enhanced, but false activation of key functions occurs during browsing
Solution Approach 1:
The click pad dynamically switches between key function mode and touch function mode based on user input characteristics. When a pressing operation meets the key input condition (sufficient force and duration), the system activates key functions; otherwise, it maintains touch function mode for browsing operations. This dynamic switching resolves the contradiction by adapting the functionality to the user's intent.
Solution Approach 2:
The system changes the operational parameters of the click pad based on the type of input detected. By monitoring pressing force, duration, and location, the system adjusts whether the click pad operates in key function mode or touch function mode. This parameter-based differentiation allows the same hardware to reliably support both functions without false activation.
2Productivity
If the click pad is pressed to activate key functions, then input efficiency is improved, but browsing is interrupted due to false activation
Solution Approach 1:
The click pad dynamically adjusts its response based on the characteristics of the pressing operation. During browsing, light or brief touches are interpreted as touch inputs without activating key functions, while deliberate presses meeting specific criteria trigger key functions. This dynamic response prevents browsing interruptions while maintaining input efficiency.
Solution Approach 2:
The system applies preliminary anti-action by setting threshold conditions that prevent false activation of key functions during browsing. By requiring specific pressing force and duration thresholds, the system preemptively blocks unintended key activations that would interrupt browsing, while still allowing intentional key inputs to pass through.
3Adaptability or versatility
If the click pad supports multiple functions, then functionality is enhanced, but the mechanism for preventing false activation increases complexity
Solution Approach 1:
The click pad is designed as a universal input device that can perform both key functions and touch functions using the same hardware structure. By implementing a unified control mechanism that detects input characteristics and routes to appropriate functions, the patent avoids the complexity of separate hardware for each function while maintaining multi-functionality.
Solution Approach 2:
The click pad uses its own pressing characteristics (force, duration, location) to automatically determine whether to activate key functions or touch functions, without requiring external control mechanisms. This self-service approach simplifies the overall system complexity while enabling sophisticated multi-function operation through intelligent detection and classification of user inputs.
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
Enables the user to temporarily shut down or activate key functions of the click pad without influencing the device's appearance, preventing interruptions during browsing by allowing precise control over key function activation and deactivation.
Implementation Method 1
The first connecting rod has a pivot part, which is connected pivotally to a fixing base of the keyboard housing
Implementation Method 2
The second connecting rod has a third positioning part against the second driving member... The second end of the second connecting rod is wedged in the first positioning part

AI summary
A key control device for a click pad is provided that includes a first driving member, a second driving member, a first connecting rod, and a second connecting rod. When the first driving member is pressed, it drives the first connecting rod for activating the key functions of the click pad. When the second driving member is pressed, it drives the second connecting rod and drives the first driving member to drive the first connecting rod to recover to the original position for shutting down the key functions of the click pad. The key control device controls the activation or shutdown of the key functions of the click pad. Because the key control device is hidden below a click pad of a notebook computer, the appearance of an electronic device is not effected.
