Touchpad Module Fulcrum Mechanism for Full-Surface Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touchpad modules are unable to press down the entire surface of the touch member, resulting in localized pressing capabilities.
Innovation Solution
A touchpad module design featuring a base plate, touch member, switch, elastic element, first supporting element, and second supporting element, where the touch member can be swung toward the base plate using these elements as fulcra, allowing the entire surface to be pressed down by distributing force across multiple regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch member is connected with the supporting structure through iron elements or plastic structures, then the touch member can be swung upwardly or downwardly, but only the position of the touch member that is not aligned with the supporting structure can be pressed down
Solution Approach 1:
The supporting structure is divided into multiple independent supporting elements (first supporting element, second supporting element, etc.) that are distributed at different positions beneath the touch member. Each supporting element can independently support or release different regions of the touch member, enabling localized pressing operations across the entire surface while maintaining a modular and manageable structural complexity.
2Ease of operation
If the touch member is swung toward the base plate using supporting elements as fulcra, then the entire surface can be pressed down, but the structural design becomes more complex
Solution Approach 1:
Each supporting element serves multiple functions: it acts as a fulcrum for the touch member to swing, provides elastic support through its elastic element, and can be independently controlled to enable pressing at different locations. This multi-functionality reduces the need for separate components for each function, thereby achieving full surface pressing capability without proportionally increasing overall structural complexity.

Function Achieved in This Case
Enables the entire region of the touch member to be pressed down, overcoming the limitation of localized pressing, while simplifying the structural design to reduce manufacturing costs and weight.
Implementation Method 1
the touch member 13 is swung upwardly relative to the triggering part 12 in response to the elastic force of the supporting structure 11

AI summary
A touchpad module includes a base plate, a touch member, a switch, an elastic element, a first supporting element and a second supporting element. The base plate includes a triggering part. The touch member is located over the base plate. The switch is disposed on the touch member and aligned with the triggering part. The elastic element is located under the base plate. The elastic element includes a fixed part, a first swingable part and a second swingable part. The fixed part is fixed on the base plate. The first swingable part includes a first contact structure. The second swingable part includes a second contact structure. When an external force is exerted on the touch member, the touch member is swung toward the base plate relative to the first supporting element, and the second swingable part is swung away from the base plate.
