Pet Hair Removal Comb with Sliding Button and Connecting Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pet combs often get stuck in knotted hair, leading to delayed force transmission and user fatigue due to increased push force required, resulting in a poor grooming experience.
Innovation Solution
A pet hair removal comb design featuring a knife holder assembly, handle assembly, and a hair removal push plate with a connecting rod and force applying arm that allows for immediate and effort-saving operation by sliding the button assembly, which reduces the effort needed to push the push plate through the connecting rod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional pet comb is used to comb knotted hair, then the comb teeth can reach the knotted areas, but the comb gets stuck and requires increased push force
Solution Approach 1:
The patent extracts the blade edge function from the traditional comb structure, creating a separate hair cutting device that removes knotted hair before combing. This extraction eliminates the sticking problem by preventing knots from interfering with comb teeth movement, thereby reducing the push force required during combing operations.
Solution Approach 2:
The blade edge performs preliminary action by cutting and removing knotted hair before the comb teeth attempt to comb the hair. This preliminary removal of knots ensures that subsequent combing operations proceed smoothly without resistance, directly addressing the force requirement issue.
2Ease of operation
If a hair removal push plate is pushed directly without mechanical advantage, then the structure is simple, but the user experiences finger fatigue after long-term use
Solution Approach 1:
The patent introduces a dynamic button assembly that can slide along the handle assembly, transforming the static push plate structure into a dynamic system. This allows the user to apply force more efficiently by sliding the button, which then actuates the connecting rod and push plate mechanism, reducing direct finger fatigue while maintaining operational control.
Solution Approach 2:
The button assembly serves as an intermediary between the user's finger and the hair removal push plate. Instead of directly pushing the push plate, the user slides the button, which then transmits and amplifies the force through the connecting rod mechanism, reducing the effort required from the user's finger.
3Ease of operation
If there is a gap between the rotating member and button in the push mechanism, then the structure allows movement, but the force transmission is delayed
Solution Approach 1:
The connecting rod is pre-positioned and movably connected to both the button assembly and push plate, eliminating gaps before force transmission is needed. This preliminary positioning ensures that when the user slides the button, force is transmitted immediately to the push plate without any delay caused by gap closure, achieving responsive and timely force transmission.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures timely response and reduces user effort, enhancing the overall grooming experience by providing a sensitive and effort-saving mechanism for removing pet hair, especially when dealing with knotted hair.
Implementation Method 1
a connecting rod is provided between the button assembly and a back surface of the push plate; two ends of the connecting rod are respectively movably connected with the button assembly and the push plate; the button assembly is configured to slide to push, through the connecting rod, the push plate to move
Implementation Method 2
the connecting rod is arranged with a force applying arm; a back surface of the hair removal push plate is provided with an arc force-bearing surface; a front end of the force applying arm is pressed tightly on the arc force-bearing surface; when the button assembly slides forward and backward, the front end of the force applying arm is slidable in close contact on the arc force-bearing surface
