Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switch devices are prone to damage and have complex structures that increase manufacturing costs and reduce electro-conductive performance, leading to unreliable circuit opening and higher risk of failure.
Innovation Solution
A switch device structure featuring a main body with a base seat and an elastic unit mounted within a cavity, where the elastic unit includes a fixed section and a free section with angled components to push contacts into or away from each other to close or open the circuit, eliminating the need for compression springs and simplifying the leaf spring design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression springs are disposed between the case and connection seat to provide elastic force, then the circuit can be opened and closed, but the structure becomes complex and the springs may fail to push the connection seat reliably when damaged
Solution Approach 1:
The patent extracts the elastic force generation function from the compression spring and transfers it to the base seat structure itself. The base seat is designed with an elastic portion that directly provides the pushing force to the connection seat, eliminating the need for separate compression springs and reducing structural complexity while maintaining reliability.
Solution Approach 2:
The patent merges the base seat and the elastic force generation function into a single integrated structure. The elastic portion is formed as an integral part of the base seat, combining the support function and the elastic pushing function into one component, thereby simplifying the overall device structure.
2Reliability
If first and second leaf springs with bent sections and U-shaped structures are used to provide elastic action force, then the circuit can be closed and opened, but the manufacturing cost increases due to complicated structures and bending operations
Solution Approach 1:
The patent extracts the elastic action force provision function from the complex leaf spring assembly and transfers it to the base seat's elastic portion. This eliminates the need for separately manufactured leaf springs with bent sections and U-shaped structures, significantly reducing manufacturing complexity and cost.
Solution Approach 2:
The patent combines the base seat and elastic force generation into a single integrated component. The elastic portion is formed integrally with the base seat, eliminating the need for separate leaf spring components and their associated complex bending and punching operations.
3Ease of operation
If the first leaf spring is made thinner with hollow section structure to increase elastic action force and motional range, then the switching range is improved, but the electro-conductive performance is lowered
Solution Approach 1:
The patent extracts the elastic force generation function from the leaf spring and assigns it to the base seat's elastic portion. This allows the wire connection module's contact arm to be designed with optimal thickness for electro-conductive performance without being constrained by the need to provide elastic force.
Solution Approach 2:
The patent merges the elastic force generation function into the base seat structure, separating it from the wire connection module. This functional separation allows the contact arm to be optimized for electrical conductivity while the base seat's elastic portion is optimized for mechanical force generation.

AI summary
A switch device structure provides an ensuring system to improve the shortcoming of the conventional switch device. The switch device structure includes a main body and an operation button assembled with the main body. The main body defines a chamber in which a base seat is assembled. An operation body and a wire connection module are disposed on the base seat. The base seat is formed with a cavity in which an elastic unit is mounted. The elastic unit includes a fixed section and a free section. In response to the move of the operation body and with the fixed section serving as a fulcrum, the free section of the elastic unit can push a second contact of the wire connection module into contact with a first contact to close the circuit or away from the first contact to open the circuit.
