Sliding Display Door Structure for Compact Automatic Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with sliding doors made of hard materials like glass or sheet metal increase volume due to space occupation when opened and closed, and require manual operation, which is inconvenient for users.
Innovation Solution
A display device with a door made of a plastic sheet covered by a fabric sheet, using a sliding module with a motor, pulley, belt, and door fixing bars for automatic opening and closing, controlled by a hall sensor that detects user presence and distance to adjust door openness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a sliding door made of hard materials like glass or sheet metal is used, then the door provides good protection and structural integrity, but the volume increases due to the space occupied when the door is opened and closed
Solution Approach 1:
The patent applies a fabric sheet covering the plastic sheet to create a flexible door structure. This flexible material allows the door to be stored in a compact position behind the display when opened, significantly reducing the volume occupied compared to rigid glass or metal doors that require large opening spaces.
Solution Approach 2:
The door is designed to nest behind the display when opened, with the fabric and plastic sheets folding or retracting into a compact configuration. This nesting approach minimizes the space required for door movement while maintaining protection when closed.
2Volume of moving object
If the door is made of fabric material, then the volume occupied is minimized and design aesthetics are improved, but the door strength and durability may be reduced
Solution Approach 1:
The patent uses a composite structure consisting of a plastic sheet base layer providing structural strength and durability, covered by a fabric sheet that provides aesthetic appearance and flexibility. This combination maintains door strength while enabling compact storage and minimal volume occupation when opened.
Solution Approach 2:
The fabric sheet covering the plastic sheet creates a flexible yet protective door structure that can be compactly stored when opened, minimizing volume occupation while the underlying plastic sheet maintains necessary strength and durability.
3Device complexity
If the door is opened and closed manually, then the structure remains simple, but user convenience is reduced as users have to open the door themselves to watch videos
Solution Approach 1:
The patent implements automatic door opening and closing functionality through a sliding module with motor, pulley, and belt mechanisms. The system detects user presence and automatically opens the door when a user approaches and closes it when the user leaves, eliminating the need for manual operation and significantly improving user convenience.
Solution Approach 2:
The patent uses hall sensors to detect the presence and distance of users, providing feedback to the control system. Based on this feedback, the sliding module automatically adjusts door opening程度, enabling convenient hands-free operation while maintaining relatively simple overall structure.
4Ease of operation
If a sliding module with motor, pulley, and belt is used for automatic door operation, then user convenience is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical door operation systems with a more integrated sliding module design that combines motor, pulley, and belt mechanisms in a compact configuration. This substitution provides automatic operation improving user convenience while minimizing the space and complexity required compared to traditional mechanical systems.
