Universal Hair Clipper Battery With Drop-Preventing Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair clippers with different designs require rechargeable batteries of varying designs, leading to increased manufacturing costs and consumer expenses, and existing detachable batteries often drop when removed, causing accidents.
Innovation Solution
A rechargeable battery with a body featuring multiple indentations for different fastener members and a retaining assembly with a resilient member that maintains the battery connected to the hair clipper, preventing accidental drops during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single rechargeable battery design is used across multiple hair clipper designs, then manufacturing costs and consumer expenses are reduced, but the battery must accommodate different fastener member configurations which increases design complexity
Solution Approach 1:
The battery body is designed with multiple indentations that can accommodate different fastener member configurations, allowing a single battery design to be universally compatible with multiple hair clipper designs. This eliminates the need for different battery designs for different clippers, reducing manufacturing costs and consumer expenses.
Solution Approach 2:
The battery body is segmented with multiple distinct indentations, each capable of receiving different fastener member configurations. This segmentation allows the single battery design to adapt to various clipper designs without increasing overall complexity, as each indentation is independently configured for specific fastener types.
2Ease of operation
If the rechargeable battery is made detachable from the hair clipper, then ease of charging and replacement is improved, but the battery may be accidentally dropped during removal causing harm
Solution Approach 1:
The retaining assembly is configured to automatically engage with the battery before complete removal occurs. When the release button is actuated, the resilient member gradually disengages from the battery's groove, providing a controlled release that prevents accidental dropping while still allowing easy removal when intentionally initiated.
Solution Approach 2:
The retaining assembly acts as an intermediary mechanism between the battery and the housing. It provides a controlled interface that allows easy battery removal through button actuation while simultaneously preventing accidental drops through the resilient member's engagement with the battery groove during the removal process.
3Reliability
If a retaining assembly with resilient member is added to prevent battery drops, then safety is improved, but the device complexity increases
Solution Approach 1:
The resilient member is configured to automatically engage with and disengage from the battery's groove through spring-loaded action. When the release button is pressed, the resilient member self-adjusts its position to control the battery release, eliminating the need for complex mechanical retention mechanisms while improving safety.
Solution Approach 2:
The retaining assembly with resilient member serves as a simple intermediary component that provides reliable battery retention. The resilient member's engagement with the battery groove creates a straightforward mechanical interface that prevents accidental drops without significantly increasing overall device complexity.
