Hidden type holder device, vehicle armrest including holder device, and transportation means including the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hidden type holders in transportation means are limited in space usage, stability, and accessibility, as they occupy too much space when tall, lack stability when short, and are only usable by passengers seated next to them due to design constraints.
Innovation Solution
A holder apparatus with a stationary assembly, a movable assembly, and return springs, allowing the holder to be rotated and adjusted for use by passengers in both front and rear seats, featuring a retractable design that minimizes space usage and enhances stability through a power transmission device and guide grooves for adjustable support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the holder has a large height to stably support cups or water bottles, then the stability is improved, but the space occupied in the vehicle or armrest increases
Solution Approach 1:
The holder is designed as a retractable structure that can dynamically change its state between extended (for stable cup support) and retracted (for space saving). The holder assembly includes a holder body that can move between protruding from and being retracted into the armrest, allowing the system to adapt its height based on usage requirements.
2Ease of operation
If the holder is positioned on the central console in the front row, then front seat passengers can use it, but rear seat passengers cannot use it
Solution Approach 1:
The holder is integrated into the armrest structure that serves multiple functions and can be accessed by both front and rear seat passengers. The armrest itself can be positioned to serve different passengers, and the holder within it can be retracted into or extended from the armrest to provide universal access to multiple users in different seating positions.
3Adaptability or versatility
If the holder is fixed to the rotatable device and rotated by 180 degrees, then the holder can face different directions, but the bottom and top portions are reversed making it impossible to accommodate cups
Solution Approach 1:
The holder assembly is designed to dynamically adjust its position relative to the armrest. When the armrest rotates, the holder can be retracted into or extended from the armrest to maintain proper orientation for cup accommodation. This dynamic adjustment ensures that regardless of armrest rotation, the holder can always be positioned correctly to hold cups.
4Volume of moving object
If the holder is retracted when not in use to save space, then space efficiency is improved, but the holder cannot provide stable support when needed
Solution Approach 1:
The holder employs a retractable mechanism that allows it to transition between a retracted state (saving space when not in use) and an extended state (providing stable support when needed). This dynamic capability enables the holder to optimize both space utilization and support stability based on real-time usage requirements.
