Conforming Wrapper for Internal Component Adhesive Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable computing devices face challenges in securely mounting internal components due to limited space and the difficulty of removing double-sided adhesive tape without damaging surfaces or components during repairs.
Innovation Solution
A conforming wrapper made of flexible materials like polycarbonate or polyethylene is used to enclose and secure internal components within the device, utilizing adhesives to attach the wrapper to both the component and the device's surface, allowing for easy removal without surface damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If double-sided adhesive tape is used to secure internal components, then the components are firmly mounted and withstand jarring and jolting, but the adhesive tape becomes difficult to remove and can damage surfaces and components during repair
Solution Approach 1:
The adhesive system is segmented into two distinct parts: a permanent adhesive layer for mounting the component and a removable adhesive layer for securing the wrapper. This segmentation allows each adhesive to have different removal characteristics, with the removable adhesive designed to be easily peeled away during repair while the permanent adhesive remains firmly bonded.
Solution Approach 2:
The wrapper acts as an intermediary element between the component and the permanent adhesive. The wrapper is secured with removable adhesive, creating a intermediate layer that can be easily removed during repair, thereby protecting the permanent adhesive and component surfaces from damage while maintaining secure mounting during normal use.
2Length of moving object
If the portable computing device size is reduced, then the device becomes smaller and lighter, but there is less space for internal components and harder to secure them adequately
Solution Approach 1:
The wrapper is constructed from flexible materials such as polycarbonate or polyethylene that can conform to the contours of internal components. This flexibility allows the wrapper to adapt to irregular shapes and fit into tight spaces within the reduced device form factor, providing adequate securing without requiring additional space.
Solution Approach 2:
The adhesive system uses composite material structure with different adhesive layers having distinct properties. The permanent adhesive provides strong bonding for secure mounting, while the removable adhesive allows easy removal during repair. This composite approach resolves the contradiction between strong securing and ease of repair in compact devices.
3Strength
If strong adhesive is used to secure components, then the components remain firmly in place during jarring and jolting, but the force required to remove the adhesive can damage surfaces and components
Solution Approach 1:
The adhesive system is divided into permanent and removable adhesive layers with different bonding strengths and removal characteristics. The permanent adhesive provides strong bonding to withstand jarring and jolting, while the removable adhesive is designed to be easily peeled away without damaging surfaces or components during repair.
Solution Approach 2:
The wrapper serves as an intermediary that is secured with removable adhesive between the component and the permanent adhesive. This intermediate layer protects the permanent adhesive and component surfaces from direct contact and potential damage during removal, allowing the permanent adhesive to maintain strong bonding without causing surface damage.

Function Achieved in This Case
The solution provides secure mounting and easy access for repairs by conforming to component shapes, absorbing shocks, and allowing for vibration isolation, while minimizing strain on components and surfaces during use and removal.
Implementation Method 1
shrinking the heat shrinkable wrapper around at least the portion of the internal component by applying heat to the heat shrinkable wrapper
Implementation Method 2
securing a first end of the flexible film to an outer housing of the internal component with a first adhesive and securing a second end of the flexible film to the outer housing of the internal component with a second adhesive

AI summary
Methods and systems for adhering internal components in a portable computing device are described. In some embodiments, an internal component adhesive removal system can include a conforming wrapper. In one embodiment, the conforming wrapper can wrap around a portion of an outer surface of the internal component. The conforming wrapper can secure and at least partially enclose the internal component such that the internal component is sufficiently constrained to protect the internal component from damage during movement of the portable computing device during normal use. In some embodiments, the wrapper comprises one or more shock absorbing features. In some embodiments, the wrapper comprises a feature configured to tear to facilitate removal of the internal component from the portable computing device.
