Waterproof Structure for Electronic Device Side Entries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproof structures in electronic devices, particularly those with a closed-curve shape between the front and rear cases, fail to completely prevent moisture penetration through side keys, power keys, or holes, leading to inefficiencies in manufacturing and repair.
Innovation Solution
A waterproof structure is implemented where a first waterproof member is disposed on the front case and a second waterproof member is disposed on the rear case, with overlapping portions to enhance sealing, thereby reducing waste and simplifying repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an integrated waterproof member of closed-curve shape is arranged between front case and rear case, then waterproofing coverage is improved, but manufacturing waste increases and repair difficulty increases
Solution Approach 1:
The waterproof structure is divided into multiple separate waterproof members: a first waterproof member arranged on the front case and a second waterproof member arranged on the rear case. This segmentation allows each member to be manufactured independently with minimal waste, while collectively providing comprehensive waterproofing coverage when assembled together.
2Reliability
If an integrated waterproof member of closed-curve shape is arranged between front case and rear case, then waterproofing coverage is improved, but repair difficulty increases
Solution Approach 1:
The waterproof structure is divided into multiple separate waterproof members that can be independently accessed and replaced. When waterproofing is needed, only the affected waterproof member (first or second) needs to be removed and replaced, rather than replacing an entire integrated closed-curve waterproof member, significantly easing repair difficulty.
3Reliability
If waterproof structure is arranged in compressed state between front case and rear case, then sealing effect is improved, but moisture penetration through side entries cannot be completely prevented
Solution Approach 1:
The waterproof members extend not only between the front and rear cases (one dimension) but also along the side faces of the housing (another dimension). This multi-dimensional arrangement ensures that waterproofing coverage includes side entries, preventing moisture penetration through side keys, power keys, or holes while maintaining the compressed sealing effect between cases.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively prevents or reduces moisture penetration through side entries, is economical by minimizing waste during manufacturing, and facilitates easier repair due to the divided and overlapping design of the waterproof members.
Implementation Method 1
The waterproof structure is formed of an elastic material and has a structure capable of previously preventing or reducing the penetration of moisture introduced into a side face of the housing

AI summary
An electronic device includes a front plate and a back plate. The electronic device includes a front case including a first face facing the front plate, a second face facing the back plate, and a first side face oriented in a lateral direction, where the front case is arranged between the front plate and the back plate. The electronic device includes a rear case including a third face facing the front plate, a fourth face facing the back plate, and a second side face oriented in the lateral direction, where the rear case is arranged between the front case and the back plate and is coupled to the front case. The electronic device includes a waterproof structure including a first waterproof member disposed on the front case and a second waterproof member disposed on the rear case.
