Push Button Cable Routing via Guide Member to Block Dust Ingress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face challenges in ensuring reliable and durable connections between push buttons and press switches, particularly due to issues with water and dust ingress through the through holes, which can lead to poor contact and operational difficulties.
Innovation Solution
The electronic apparatus incorporates a watertight member and bonding member configuration to cover and secure the through holes, ensuring that the flexible printed wiring board is fixed within the housing, thereby preventing water and dust ingress and maintaining a stable connection between the push button and press switch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cable is routed directly between the push button and press switch through a through hole, then the connection is simple and short, but water and dust can ingress through the through hole causing poor contact and operational difficulties
Solution Approach 1:
A cable guide member is introduced as an intermediary component between the push button and press switch. This guide member provides a protected pathway for the cable, preventing direct exposure to water and dust while maintaining the electrical connection. The cable is routed through the guide member rather than directly through the through hole, creating a barrier against harmful factors.
2Adaptability or versatility
If the watertight member is deformed to accommodate cable routing, then the cable can be routed through the housing, but the deformation reduces the watertight sealing performance
Solution Approach 1:
The cable routing function and watertight sealing function are separated into distinct components. The cable guide member handles cable routing while the watertight member maintains sealing without deformation. This segmentation allows each component to optimize its specific function without compromising the other.
Solution Approach 2:
The cable guide member serves as a mediator that enables cable passage through the housing without requiring the watertight member to deform. The guide member provides the necessary opening or pathway for the cable while the watertight member remains intact and maintains its sealing performance.
3Reliability
If the cable is fixed to the housing at multiple points, then the cable position is stable and connection is reliable, but the device complexity increases
Solution Approach 1:
The cable fixing function is merged with the cable guide member. The guide member simultaneously provides structural support, cable routing, and positioning functions in a single integrated component. This eliminates the need for separate fixing structures at multiple points, reducing device complexity while maintaining cable stability.

AI summary
An electronic apparatus is disclosed. An electronic apparatus comprises a housing, a press switch, a push button, and a cable. The press switch is located in the housing. The push button is a button for pressing the press switch. The cable connects a first electronic part located in the push button to a second electronic part located closer to the inside than the first electronic part and located in the housing. The cable has a fixed portion that is part of the cable between the first electronic part and the second electronic part and that is fixed to the housing. The push button does not face the fixed portion in a direction in which the push button moves by being pushed.
