Seat-Back Cup Holder Mounting for Variable Theater Seat Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cup holders for stadium or theater seating often face difficulties in mounting due to variations in the gap size between adjacent seats, leading to inconsistent installation and usability issues.
Innovation Solution
A cup holder design that mounts directly to a single seat back, featuring a mounting arm with a receiving portion that hooks around the seat back frame and a fastening portion that secures via fasteners, allowing for adjustable positioning and secure attachment without relying on the gap between seats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cup holder is mounted to the back of two adjacent seats using the gap between seat backs, then the cup holder can be positioned between seats for use by persons sitting in front chairs, but variations in gap size between different seats cause difficulties in mounting and inconsistent installation
Solution Approach 1:
The mounting bracket is divided into two separate portions: a first portion that mounts to the rear of the first seat back, and a second portion that mounts to the rear of the second seat back. This segmentation allows each portion to be independently adjusted to accommodate variations in seat back dimensions and gap sizes, resolving the mounting difficulty caused by inconsistent gaps between adjacent seats.
Solution Approach 2:
The mounting bracket incorporates adjustable positioning mechanisms that allow it to adapt dynamically to different gap sizes between seat backs. The bracket can be adjusted along the seat back frames to accommodate varying distances, enabling consistent installation across different seat configurations without requiring precise pre-measurement or custom fabrication.
2Manufacturing precision
If a cup holder is mounted to a single seat back, then mounting consistency is improved by eliminating dependence on gap size between seats, but the cup holder must be positioned at the rear of one specific seat rather than between seats
Solution Approach 1:
The mounting bracket is designed with universal adaptability to mount to various seat back configurations. By incorporating adjustable features that work with standard seat back frames, the bracket achieves consistent mounting across different locations while maintaining the ability to serve multiple seating positions, effectively combining positioning flexibility with mounting consistency.
3Strength
If screws are used to fasten the cup holder bracket to seat backs, then secure attachment is achieved, but the varying dimensions of seat backs create installation difficulties
Solution Approach 1:
The bracket is segmented into multiple adjustable portions that can be independently positioned and secured to different seat backs. This segmentation allows installers to accommodate varying seat back dimensions by adjusting each portion's position before securing with screws, maintaining strong attachment while simplifying installation across different seat configurations.
Solution Approach 2:
The bracket design incorporates adjustable parameters such as position along the seat back frame and orientation angles. These parameters can be modified during installation to match the specific dimensions of different seat backs, enabling consistent screw fastening and secure attachment without installation difficulties caused by dimensional variations.

AI summary
A cup holder for a seat of an auditorium or theater includes a cup receiving body and a mounting arm. The cup receiving body is configured to receive and support a cup therein. The mounting arm extends from the cup receiving body and includes a receiving portion and an attachment portion. With the mounting arm extending across a side portion of a seat back frame of a single seat, and with the receiving portion receiving a front portion of the seat back frame and the mounting arm extending from the front portion of the seat back frame to a rear portion of the seat back frame, the attachment portion of the mounting arm abuts the rear portion of the seat back frame, and the attachment portion is attached at the seat back frame to secure the cup holder relative to the seat back frame.
