Component Extractor for Residue-Free Portable Computer Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for removing components from portable computing devices using adhesive tapes are difficult and often result in residue and tape breakage, especially when the tape must be pulled at an angle, which can damage components and leave adhesive residue.
Innovation Solution
A component extractor system with a compressible securing portion and an extracting portion coupled at a non-zero angle, allowing for the application of an extracting force that reduces the thickness of the securing portion at a detaching region, enabling easy detachment of components without tools, using a low friction material or edge plate to prevent tape breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive tape is used to mount components in portable computing devices, then components can be securely attached to the housing, but removing the components becomes difficult and time-consuming and leaves adhesive residue
Solution Approach 1:
The adhesive tape system is segmented into two distinct functional layers: a permanent adhesive layer for secure attachment and a removable extensible backing layer for easy removal. This segmentation allows each layer to perform its specific function optimally - the adhesive provides strong bonding while the extensible backing enables clean removal without residue.
Solution Approach 2:
The extensible backing acts as an intermediary between the permanent adhesive and the external removal force. It mediates the removal process by providing a mechanical interface that can be grasped and pulled, translating external pulling force into adhesive bond disruption while preventing direct contact with the permanent adhesive.
2Ease of operation
If adhesive tape with highly extensible backing is used to allow easy removal, then component removal becomes easier, but the tape requires sufficient clearance to pull the adhesive backing parallel to the surface, which is not available in cavity-mounted components
Solution Approach 1:
The removal mechanism transitions from a two-dimensional parallel pull to a three-dimensional angled pull. The extensible backing is designed to be pulled at an angle approximately normal to the tape surface rather than parallel to it, utilizing the third dimension (vertical clearance) to achieve removal when horizontal clearance is insufficient.
Solution Approach 2:
The pulling angle parameter is changed from parallel (0 degrees to surface) to approximately normal (90 degrees to surface). This parameter change fundamentally alters the removal mechanics, allowing the extensible backing to detach through vertical displacement rather than horizontal stretching, thereby reducing the required clearance.
3Length of stationary object
If adhesive tape is pulled at an angle normal to the surface for removal, then clearance requirements are reduced, but the tape breaks instead of detaching cleanly
Solution Approach 1:
The extensible backing is pre-configured with high elasticity and tear resistance properties before the removal operation. This preliminary design ensures that when the angled pull is applied, the backing can withstand the stress without breaking, maintaining tape integrity throughout the removal process.
Solution Approach 2:
The extensible backing provides a cushioning effect by absorbing and distributing the stress of the angled pull through its elastic deformation. This beforehand cushioning prevents stress concentration that would cause tape breakage, allowing the full force of the pull to be transmitted to the adhesive bond for clean detachment.
4Volume of moving object
If portable computing device sizes are reduced to meet user demands, then device portability improves, but component mounting systems become more constrained and removal becomes more difficult
Solution Approach 1:
The mounting system is segmented into permanent adhesive and removable extensible backing, allowing the permanent adhesive to provide compact, reliable attachment in limited space while the extensible backing provides a dedicated removal interface that operates independently of the component's physical constraints.
Solution Approach 2:
The removal operation utilizes the vertical dimension (pulling at an angle normal to the surface) rather than being constrained to the horizontal plane. This dimensional change allows removal to proceed even when the component is tightly mounted in a cavity with insufficient horizontal clearance.

Function Achieved in This Case
Facilitates easy and residue-free removal of components from portable devices, reducing the risk of damage and adhesive residue, and allows for efficient servicing and repair without specialized tools.
Implementation Method 1
applying an extracting force to the extracting portion transfers the extracting force to the compressible securing portion by way of the junction, reducing the thickness of the compressible securing portion at a detaching region from a securing thickness to a reduced thickness
Implementation Method 2
The junction is aligned over the low friction material such that an extracting force applied to the extracting portion transfers to the compressible securing portion by way of the junction

AI summary
The described embodiments relate generally to components used in a portable computing device and more particularly to mounting a component with a component extractor that allows a component to be removably affixed to a portable computing device. The component extractor can include a compressible securing portion configured to secure the component to the portable computing device and an extracting portion arranged to apply an extracting force to the compressible securing portion to detach the component from the portable computing device. The compressible material can be made of a highly extensible material. In one embodiment, a low friction material can be provided along an edge of the component such that the component extractor slides along the edge during an extraction procedure.
