Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Keyboards generate noise due to friction and collision between the balance rod and carrier during key cap actuation, causing user discomfort.
Innovation Solution
A key structure incorporating a buffer layer and circuit film positioned between the balance rod and carrier, reducing friction and collision by obstructing the balance rod's movement, thereby minimizing noise during actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the balance rod is connected with the carrier to improve stability during actuation, then the stability is improved, but friction and collision between the balance rod and carrier are caused, generating noise
Solution Approach 1:
The patent introduces a buffer layer as an intermediary component between the balance rod and the carrier. This buffer layer mediates the interaction between the balance rod and carrier, preventing direct friction and collision while maintaining the connection and stability. The buffer layer absorbs the harmful friction and collision effects, allowing the balance rod to move smoothly without generating noise.
2Stability of the object's composition
If the balance rod is connected with the carrier to improve stability during actuation, then the stability is improved, but friction between the balance rod and carrier is caused
Solution Approach 1:
The buffer layer serves as a mediating component that reduces friction between the balance rod and carrier. By placing the buffer layer in between, the direct contact and friction are eliminated, allowing the balance rod to move smoothly while maintaining stable connection to the carrier.
3Stability of the object's composition
If the balance rod is connected with the carrier to improve stability during actuation, then the stability is improved, but collision between the balance rod and carrier is caused
Solution Approach 1:
The buffer layer acts as a protective intermediary that prevents direct collision between the balance rod and carrier. During actuation, the buffer layer absorbs impact forces and prevents the balance rod from colliding directly with the carrier, thereby eliminating collision-related noise and damage while maintaining connection stability.

AI summary
The disclosure provides a key structure, including a carrier, a buffer layer, a circuit film, a balance rod and a key cap. The carrier includes a body and a positioning element protruding from the body. The positioning element has a positioning hole. The buffer layer is disposed around the positioning hole. The circuit film and the balance rod are disposed on the body. The balance rod has an opposite first end portion and a second end portion. The first end portion passes through the positioning hole and presses against the buffer layer. The key cap is connected with the second end portion, and the circuit film and the balance rod are positioned between the key cap and the body.
