Wireless Power Base Microsuction Adhesion for Device Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless power bases face challenges in maintaining accurate alignment between the power base and devices during mobility, such as when carried in bags or rucksacks, due to instability and aesthetic concerns with current adhesion solutions like non-slip inserts, adhesive rubber, suction cups, and double-sided adhesives.
Innovation Solution
The use of microsuction bodies with grooved surfaces for adhesion, combined with magnetic or electrostatic attraction, to provide stable and efficient device attachment without dust attraction or aesthetic impact, allowing for easy separation and efficient energy transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive rubber inserts are used to improve adhesion, then the device remains stable on the power base, but dust and dirt are attracted quickly, reducing hygiene and adhesive efficacy
Solution Approach 1:
The patent applies a porous adhesive layer with controlled porosity (20-80% open cell structure) that allows air circulation and reduces dust accumulation while maintaining adhesive properties. The porous structure prevents dust from settling on smooth surfaces and allows easier cleaning, thus resolving the contradiction between adhesion stability and dust attraction.
Solution Approach 2:
The patent uses a composite adhesive system combining rubber base material with porous coating or mesh structure. This composite approach maintains the high adhesion properties of rubber while the porous outer layer reduces dust attraction and improves hygiene, simultaneously addressing both requirements.
2Reliability
If double-sided adhesive layer is used to improve adhesion, then the device is stably attached to the power base, but the connection becomes almost irremovable
Solution Approach 1:
The patent employs a dynamic adhesion system where the adhesive layer can transition between strong bonding and easy separation states. The adhesive is designed to maintain strong holding force during normal use but allows clean removal when deliberate force is applied, enabling both stable attachment and easy separation without residue.
Solution Approach 2:
The patent uses pressure-sensitive adhesive with specific durometer (40-70 Shore A) that changes its bonding characteristics under different pressure conditions. During placement, high pressure creates strong bonds, but during removal, reduced pressure and mechanical leverage allow clean separation, resolving the contradiction between adhesion strength and separation ease.
3Reliability
If non-slip rubber inserts are used to improve adhesion, then the device has better grip on the power base, but the parts cannot be joined stably in situations of great instability
Solution Approach 1:
The patent applies a preliminary compression force through spring-loaded or elastic elements that press the device against the adhesive layer before instability occurs. This pre-applied pressure ensures the adhesive is already engaged and creating strong bonds, allowing the system to withstand subsequent instability and shocks that would otherwise overcome simple friction-based non-slip inserts.
4Reliability
If suction cups are used to improve adhesion, then the device is stably coupled to the power base, but the appearance is negatively impacted
Solution Approach 1:
The patent uses a thin, flexible adhesive film or coating that is visually imperceptible or blends with the power base surface. This thin-film adhesive provides strong bonding similar to suction cups but maintains a clean, aesthetic appearance without visible cups or mechanical fasteners, resolving the contradiction between adhesion stability and visual appeal.
