Integrated Silicone Switch Packing for Waterproof Electronic Keys
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switch actuators lack waterproofing, necessitating additional components, increasing manufacturing costs and complexity when equipping multiple switches.
Innovation Solution
A switch packing with an integrated switch mechanism and sealing part, formed from silicone resin, providing both operational feedback and waterproofing by being elastically deformed to prevent liquid penetration, thus eliminating the need for separate waterproofing members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional actuator is used for each switch, then the switch can be operated, but waterproofing requires additional members increasing manufacturing cost
Solution Approach 1:
The actuator and sealing part are merged into a single integrated component made of elastic material. This combination eliminates the need for separate waterproofing members while maintaining both switching operation and waterproofing functions, thereby reducing manufacturing cost and simplifying assembly
Solution Approach 2:
The integrated actuator-sealing part performs multiple functions simultaneously: it provides the elastic deformation needed for switch operation and acts as a waterproof seal. This multi-functional design reduces the total number of components and manufacturing steps
2Ease of operation
If separate actuators are provided for multiple switches, then each switch can be independently operated, but the number of components and assembly complexity increases
Solution Approach 1:
Multiple actuators and sealing parts are merged into a single integrated component that accommodates multiple switches. Each switch maintains independent operation through its own switch element, while the shared integrated actuator-sealing part reduces overall component count and simplifies assembly

Function Achieved in This Case
The integrated switch packing reduces production costs and enhances operational feel while ensuring waterproofing, simplifying the assembly process and improving the electronic key's functionality.
Implementation Method 1
a switch mechanism part disposed between an operation button and a switch element, and configured to be elastically deformed by pushing the operation button so as to have the switch element change to a first state and provide an operational feeling via the operation button
Implementation Method 2
a sealing part to prevent penetration of a liquid, wherein the switch mechanism part and the sealing part are integrated with each other
