Housing Retaining System for Component Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Housings made from deformable materials in electronic devices face challenges such as component misalignment and damage due to deformation during drops, leading to disconnections and unacceptable performance.
Innovation Solution
A retaining system is implemented, comprising a retaining protrusion on a protective cover and a retaining member on the housing, which cooperate to inhibit deformation of the housing's sidewalls, maintaining component alignment and preventing disconnections by securing internal components relative to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pliable housing is used to provide design flexibility, then ease of manufacture and adaptability are improved, but the housing deforms under load causing component misalignment and disconnection
Solution Approach 1:
The housing is divided into multiple segments or sections, each with different rigidity characteristics. The pliable portions provide design flexibility while rigid portions maintain component alignment and prevent deformation under load.
Solution Approach 2:
Different regions of the housing have different mechanical properties - some areas are made pliable for design flexibility while other areas are reinforced or made rigid to maintain structural integrity and prevent component misalignment during drop events.
2Reliability
If the housing is made rigid to prevent deformation, then component alignment is maintained, but design flexibility and adaptability are reduced
Solution Approach 1:
The housing structure is segmented into rigid and pliable zones, allowing the rigid zones to maintain component alignment while pliable zones provide design flexibility and shock absorption.
Solution Approach 2:
The housing employs local quality variations where specific areas are reinforced for structural stability while other areas remain flexible, achieving both component alignment and design adaptability simultaneously.
3Reliability
If internal components are secured rigidly to prevent shifting, then reliability is improved, but the housing cannot deform to absorb impact energy
Solution Approach 1:
The internal component mounting structure is divided into rigid mounting points for component stability and flexible connecting regions for impact energy absorption.
Solution Approach 2:
Different portions of the component securing mechanism have different rigidity - local rigid zones maintain component position while flexible zones deform to absorb impact energy during drop events.
