Solution Overview
Problem
Hair building solids, typically powders and fibers used to address hair loss, face challenges in maintaining electrostatic charge for effective adherence due to factors like sieve design and material composition, leading to inconsistent performance and reduced life expectancy.
Innovation Solution
A dispenser with integrated electrostatic charge control means, including conductive materials and vibration mechanisms, to alter and maintain the electrostatic charge on hair building solids, ensuring consistent adherence and extended usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-piece sieve is used for dispensing solids, then the device structure is simple, but the electrostatic charge control capability is insufficient
Solution Approach 1:
The single-piece sieve is divided into multiple separate sieves arranged in sequence. This segmentation allows each sieve to perform specific functions: the first sieve dispenses solids while the second sieve (made of conductive material) neutralizes or controls electrostatic charge. The segmentation resolves the contradiction by adding charge control capability without requiring a completely complex new structure.
Solution Approach 2:
A conductive intermediary material (second sieve) is introduced between the solids and the external environment. This intermediary acts as a charge control mechanism that can neutralize or regulate electrostatic charge on the solids during dispensing, thereby improving reliability without significantly complicating the overall device.
2Reliability
If electrostatic charge is built up on solids surface, then adherence to hair/scalp is improved, but charge discharge to neutral surface reduces effectiveness
Solution Approach 1:
The conductive sieve is positioned to continuously interact with solids as they pass through the dispenser. This continuous interaction ensures that electrostatic charge is maintained or restored during the entire dispensing process, preventing premature discharge and extending the duration of effective adherence performance.
Solution Approach 2:
The system uses the dispensing process itself to maintain electrostatic charge. As solids contact the conductive sieve during normal operation, the charge is automatically controlled or restored without requiring external intervention, thereby maintaining adherence effectiveness throughout the product's usage life.
3Reliability
If conductive material is used for charge control, then electrostatic charge can be controlled, but insulation from other objects becomes necessary
Solution Approach 1:
Conductive material is used locally and specifically where charge control is needed (the second sieve), rather than throughout the entire device. This localized use of conductive material minimizes the need for extensive insulation, as only the areas surrounding the conductive sieve require insulating properties to prevent unwanted charge discharge.

Function Achieved in This Case
The dispenser effectively manages electrostatic charge, enhancing the adherence and longevity of hair building solids by controlling charge buildup and distribution, improving user experience and product performance.
Implementation Method 1
the electrically conductive means is a metal strip provided at least partially along an outside of the dispenser, the dispenser including a communicating hole between the inside and outside of said dispenser, the hole being at least partially covered by said metal strip such that at least some of the solids within said dispenser are contactable with said metal strip whereby any charge on the suface of at least some of the solids stored in the dispenser is neutralised when a user holds the dispenser in use and contacts with the metal strip
Implementation Method 2

AI summary
Hair building solids are preferably retained in place on hair by static charge. To improve the control of static charge on the solids the invention provides a hair building solids dispenser (10) for storing and dispensing hair building solids (50) comprising first electrostatic charge control means for altering and/or maintaining an electrostatic charge on a surface of at least some of said solids contained within, and/or as dispensed from, said dispenser, wherein at least a substantial portion of the exterior surface of the dispenser comprises substantially electrically non-conductive material, the first electrostatic charge control means being an electrically conductive means (80) for providing an electrical connection between the inside and outside of the dispenser.
