Double-Hook Bezel Attachment for Secure Tablet Holder Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seating systems lack a secure and efficient mechanism to attach tablet devices, allowing for hands-free viewing during travel, without requiring additional fasteners or complex design features.
Innovation Solution
A double hook attachment mechanism between a housing and a bezel, where the bezel includes a projection and the housing has a lip and hook, allowing for secure alignment and retention without additional parts or user calibration, ensuring the bezel remains fixed to the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure attachment mechanism is implemented to prevent bezel separation, then reliability is improved, but device complexity increases due to additional fasteners or complex design features
Solution Approach 1:
The patent combines the hook and lip attachment features into a single integrated housing component, eliminating the need for separate fasteners. The hook extends from the housing and the lip is formed on the housing, creating a unified attachment mechanism that secures the bezel without additional parts.
Solution Approach 2:
The attachment mechanism is designed to be self-aligning and self-securing. The projection on the bezel automatically aligns with the hook and lip during installation, and the spring-loaded hook engages with the projection to maintain secure attachment without requiring user calibration or additional fastening actions.
2Strength
If additional fasteners are used to secure the bezel to the housing, then attachment strength is improved, but ease of manufacture deteriorates due to additional assembly steps
Solution Approach 1:
The housing is designed to integrate the attachment features directly into its structure. The hook and lip are formed as part of the housing body, eliminating the need for separate fastener components and reducing assembly steps to a simple snap-fit operation.
Solution Approach 2:
The attachment mechanism is segmented into functional elements (hook, lip, projection) that can be molded into the housing and bezel separately, then assembled through a simple insertion and rotation motion, simplifying the manufacturing process while maintaining strength.
3Reliability
If a complex attachment mechanism with multiple parts is used, then reliability is improved, but productivity deteriorates due to additional assembly time
Solution Approach 1:
By consolidating the attachment features into the housing structure itself, the number of parts to be assembled is reduced. The single-piece housing with integrated hook and lip eliminates the need to assemble multiple fasteners, significantly reducing assembly time while maintaining secure attachment.
Solution Approach 2:
The hook and lip are pre-formed during housing manufacturing, and the projection is pre-formed on the bezel. This preliminary preparation allows for rapid assembly where the bezel is simply inserted and rotated into place, eliminating the need for additional fastening operations during assembly.

AI summary
A tablet device holder assembly may include a housing defining an housing opening and including a housing lip arranged on a first side of the housing above the housing opening, and a removable bezel having a projection configured to extend through the housing opening and defining a projection opening that when the bezel is rotated to an installed state, the lip is received within the projection opening to maintain the bezel on the housing.
