Wet Shaving Razor Attachment Grip Insert Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination shaving and trimming devices are bulky, difficult to use, and the wet shaving attachment can be too light, making it hard to grip and maneuver for comfortable shaving, especially when used independently of the trimmer.
Innovation Solution
A battery-operated trimmer with a wet shaving razor attachment connected via a releasable locking mechanism, featuring a connecting member with an overhanging shoulder and hooks for secure attachment, and a grip insert that attaches to the connecting member to enhance grip and control during independent use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the wet shaving attachment is designed to be lightweight for travel convenience, then portability is improved, but grip comfort and maneuverability deteriorate when used independently
Solution Approach 1:
The wet shaving attachment is divided into separate functional components: a lightweight connecting member for attachment to the trimmer and a separate grip insert that can be independently attached to the connecting member. This segmentation allows the attachment to remain lightweight for travel while providing grip enhancement when needed for independent use.
Solution Approach 2:
The grip insert is designed to be dynamically attachable and detachable from the connecting member, allowing the user to adapt the device configuration based on usage needs. When traveling, the grip insert can be removed to minimize weight; when shaving independently, the grip insert can be attached to improve ergonomics and control.
2Reliability
If the connecting member structure is made robust to prevent unintended disengagement during use, then reliability is improved, but ease of attachment and removal deteriorates
Solution Approach 1:
The connecting member incorporates curved or rounded geometric features that guide the attachment and detachment motions, making the connection process intuitive and easy while maintaining secure engagement during use. The curved geometry naturally directs the user's hands during attachment and provides mechanical advantage for easy release.
Solution Approach 2:
The connecting member serves as an intermediary component between the trimmer and the wet shaving cartridge, providing a standardized interface that simplifies attachment and removal. The connecting member's design includes features that mediate the connection process, making it easy to attach and detach while ensuring reliable connection during operation.
3Weight of moving object
If the wet shaving attachment is designed with minimal weight for travel, then portability is improved, but the attachment may be too light to provide comfortable shaving when used independently
Solution Approach 1:
The grip insert acts as a counterweight component that can be attached to the lightweight connecting member when independent shaving is required. This counterbalances the minimal weight of the connecting member, providing sufficient mass for comfortable handling and control during wet shaving operations without compromising the overall portability when the insert is removed.

AI summary
A combination shaving and trimming device includes a powered trimmer and a wet-shaving razor attachment adapted for mounting over the trimmer. The wet shaving razor attachment includes a connecting member for mounting over the trimmer for wet shaving using the trimmer as the handle. A grip insert is provided that removably attaches to the connecting member for wet shaving independent of the trimmer. The combination shaving and trimming device and the grip insert include alignment guides providing one way attachment of the connecting member to the trimmer as well as one way attachment of the grip insert to the connecting member.
