Gradient Adhesive Retention Pad for Controlled Device Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retention systems for electronic devices, such as keyboards and trackpads, require inactive border portions to function effectively, which is a limitation for devices without these features, and often require high initial force for removal, leading to potential damage and loss of control during detachment.
Innovation Solution
A retention system featuring a tray with a retention pad having a gradient distribution of adhesive and non-adhesive portions, allowing for secure attachment without the need for inactive border portions and facilitating controlled, hinged removal by varying the stickiness across the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If overhanging lips are used to retain the electronic device, then the device can be securely held, but the device must have an inactive border portion which limits adaptability
Solution Approach 1:
The retention pad features a gradient adhesive density distribution where different regions have different adhesive properties. The periphery has lower adhesive density to accommodate devices without inactive borders, while the center maintains higher adhesive density for secure retention, allowing the system to adapt to various device types
2Ease of manufacture
If uniform adhesive distribution is used on the retention pad, then manufacturing is simplified, but removal requires high initial force that can cause damage
Solution Approach 1:
The adhesive is distributed in a gradient pattern rather than uniformly. Regions with lower adhesive density are positioned to reduce the peak force required during removal, preventing damage to the electronic device while still providing secure retention through regions with higher adhesive density
Solution Approach 2:
The adhesive density parameter is varied across the retention pad surface according to a gradient distribution. This parameter change allows the system to optimize both retention strength and removal characteristics, reducing the risk of damage during device installation and removal
3Reliability
If high adhesive density is used across the entire retention pad, then retention strength is improved, but removal becomes difficult and uncontrolled
Solution Approach 1:
Different regions of the retention pad have different adhesive densities optimized for their specific functions. The center region with higher adhesive density provides strong retention, while peripheral regions with lower adhesive density facilitate easier, more controlled removal
Solution Approach 2:
Instead of applying adhesive uniformly across the entire retention pad, the invention uses partial adhesive distribution with a gradient pattern. This partial action approach provides sufficient retention strength where needed while reducing excessive adhesion in other areas, enabling easier removal
