Innovation Solution

The electronic device incorporates a waterproof structure that optimizes spatial efficiency by using a combination of housing parts and adhesive members to prevent water ingress while maintaining a sleek design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If waterproof members are added to prevent water ingress, then waterproof function is improved, but spatial efficiency deteriorates

Engineering Contradiction:
Improvewaterproof functionVSAvoidspatial efficiency
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The adhesive member is configured to extend along the boundary between first and second housing parts, combining the functions of bonding and waterproofing into a single integrated component, thereby preventing water ingress without requiring separate waterproof members that would reduce spatial efficiency

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adhesive member serves multiple functions simultaneously: it bonds the housing parts together and provides waterproof protection at the boundary, making the structure more space-efficient by eliminating the need for dedicated waterproof members

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Strength

If multiple adhesive members are used to bond housing parts, then bonding strength is improved, but device complexity increases

Engineering Contradiction:
Improvebonding strengthVSAvoidstructure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The adhesive member is configured to extend along the boundary between housing parts, combining bonding and waterproofing functions into a single integrated structure, thereby maintaining bonding strength without increasing structural complexity through multiple separate components

Inventive Principle:
Principle #5Merging (Combining)
