Spring-Biased Attachment Module for Tool-Less Accessory Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer products such as watches, cameras, and glasses often lack user-friendly attachment systems, requiring special tools for accessory removal or replacement, and may not provide adequate retention force, affecting their elegance and usability.
Innovation Solution
An attachment system featuring a removable module with a spring-biased locking mechanism that securely attaches and detaches accessories from consumer products without the need for special tools, allowing for easy interchangeability of accessories and products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional attachment mechanisms (pins, screws) are used to attach accessories to consumer products, then adequate retention force is provided, but special tools are required for attachment and removal, and the process requires technician assistance
Solution Approach 1:
The attachment system enables users to attach and detach accessories themselves without requiring technician assistance or special tools. The release mechanism is designed to be actuated by the user through simple pressure applied to the accessory, which automatically triggers the release of the retention member from the engagement feature.
Solution Approach 2:
The system extracts the attachment and detachment functions into a separate, dedicated mechanism rather than relying on permanent fastening methods. The retention member can be selectively engaged and disengaged from the engagement feature, providing removable attachment capability.
2Reliability
If robust attachment mechanisms are used to provide adequate retention force, then secure attachment is achieved, but the mechanism becomes large and adversely affects product elegance
Solution Approach 1:
The retention member is nested within the housing when not in use, with only the engagement feature extending outward. The release mechanism is integrated within the accessory itself, allowing the attachment system to maintain a sleek, minimal profile while providing secure attachment when engaged.
Solution Approach 2:
The attachment system is divided into separate functional components: the engagement feature on the housing, the retention member that can be engaged/disengaged, and the release mechanism on the accessory. This segmentation allows each component to be optimized for its specific function while maintaining overall elegance.
3Ease of operation
If simple attachment mechanisms are used to improve ease of operation, then tool-less attachment is achieved, but adequate retention force is not provided
Solution Approach 1:
The retention member acts as an intermediary between the engagement feature and the accessory, providing mechanical advantage through its interaction with the release mechanism. When the user applies pressure to the accessory, the release mechanism pivots the retention member to disengage from the engagement feature, translating small user forces into effective release action.
Solution Approach 2:
The retention member includes a curved surface that interacts with the engagement feature, allowing for smooth engagement and disengagement motion. The curved geometry enables the retention member to be pivoted easily by the release mechanism while maintaining secure engagement when locked in place.

AI summary
A removable module and a housing for an attachment system of a consumer product is described. The removable module includes a locking mechanism comprising a first portion having a substantially planar top surface and second portion that comprises a substantially non-planar bottom surface. The first portion and the second portion are coupled together. The locking mechanism also includes a first spring mechanism coupled between the first portion and the second portion. The first spring mechanism causes the first portion to be biased away from the second portion. The locking mechanism also includes a second spring mechanism. The second spring mechanism causes the substantially planar top surface of the first portion to be biased substantially flush with respect to the removable module and also causes the substantially non-planar bottom surface of the second portion to be biased proud with respect to the removable module.
