Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-functional switch devices for vehicles face challenges in providing an intuitive and cost-effective solution for integrating multiple functions without increasing manufacturing costs or compromising design aesthetics.
Innovation Solution
A multi-functional switch device with an integral panel featuring button parts that operate in a seesaw manner, coupled with a case having hooks and hook holes, allowing for restricted operation of button parts to prevent mis-operation and maintain a seamless design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple switches are integrated into a multi-functional switch device, then the number of switches that may be added increases, but the device complexity increases
Solution Approach 1:
The switch device is segmented into multiple independent button parts (first button part, second button part, third button part, fourth button part) that are formed on an integral panel. Each button part can be operated independently while sharing common structural elements (case, stopper, hook hanger), thereby increasing the number of switches without proportionally increasing overall device complexity
Solution Approach 2:
The integral panel serves multiple functions: it provides the structural base for all button parts, contains the bracket grooves for mounting, and houses the hook hangers for operational control. This universal component performs multiple roles that would otherwise require separate elements, managing complexity while supporting multiple switches
2Ease of operation
If button parts are allowed to operate freely, then ease of operation improves, but mis-operation and malfunction increase
Solution Approach 1:
The stopper is preliminarily positioned to prevent unwanted operation of button parts. When one button part is pushed, the stopper restricts the movement of other button parts before mis-operation can occur, thereby preventing malfunction while maintaining ease of operation for the intended button
Solution Approach 2:
The stopper acts as an intermediary element between the button parts. It mediates their operational independence by allowing the pushed button to move while preventing other buttons from moving simultaneously, thus ensuring reliable operation without compromising ease of use
3Adaptability or versatility
If display-based function execution is used, then the number of switches that may be added increases, but ease of operation deteriorates
Solution Approach 1:
The button parts provide self-service mechanical operation that directly activates functions without requiring complex display interactions. Each button part is designed to be intuitively operable with clear tactile feedback, eliminating the need for complicated menu execution while maintaining the ability to provide multiple functions through the multi-button configuration

AI summary
A multi-functional switch device includes: an integral panel in which four button parts are formed on the upper surface thereof, and a hook hanger including a hook hole formed at and protruding from the bottom of each button part; and a case including a stopper disposed at an upper portion of the case, and a hook protruding upward at a position corresponding to each hook hanger, the case connected to the panel. The stopper is arranged so that each button part is operated in a seesaw manner. Each hook and the hook hole are coupled to form a set gap, so that when one button part is pushed, a stroke of the corresponding button part is possible and operation of the other button parts is restricted.
