Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display apparatuses that can switch between head-mounted display (HMD) and hand-held display (HHD) forms require time and labor to change components, posing issues when multiple users need different forms frequently.
Innovation Solution
An image display apparatus with a support unit that includes a deformation portion capable of bending at predetermined parts, allowing seamless switching between HMD and HHD forms without adding or changing components, featuring adjustable stiffness and flexibility to ensure stable positioning in both forms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If component replacement is used to switch between HMD and HHD forms, then both forms can be prepared for multiple users, but it takes time and labor to switch between them
Solution Approach 1:
The support unit incorporates a deformation portion that can dynamically change its configuration between a head-mounted state (curved to fit the head) and a hand-held state (straight or bent to form a grip). This dynamic transformation eliminates the need for component replacement, allowing users to switch between HMD and HHD forms quickly by simply deforming the support unit's shape.
Solution Approach 2:
The support unit changes its physical parameters (shape, curvature, stiffness) through the deformation portion to adapt between different usage forms. By modifying the geometric parameters of the support unit, the apparatus can transition from a head-mounted configuration to a hand-held configuration without adding or removing components, thereby reducing switching time.
2Adaptability or versatility
If component replacement is used to switch between HMD and HHD forms, then both forms can be prepared for multiple users, but it requires labor to change components
Solution Approach 1:
The deformation portion enables dynamic reconfiguration of the support unit through simple mechanical movement rather than component assembly or disassembly. Users can transform the apparatus from HMD to HHD form by manually deforming the support unit, which requires minimal effort and no technical skill for component handling.
Solution Approach 2:
The support unit is designed to be self-transforming through its deformation portion, which automatically adjusts its configuration when subjected to user input. The deformation portion's inherent flexibility and structural design allow it to transition between forms without requiring additional tools, fasteners, or complex assembly procedures.
3Device complexity
If a fixed support unit is used, then the structure is simple, but it cannot switch between HMD and HHD forms
Solution Approach 1:
The support unit incorporates a deformation portion that introduces dynamic capability into an otherwise simple structure. This deformation portion can be integrated as a flexible segment, articulated joint, or shape-memory element within the support unit, allowing it to transform between configurations while maintaining overall structural simplicity and avoiding complex multi-component systems.
Solution Approach 2:
The deformation portion may utilize flexible materials or thin-walled structures that can bend, flex, or deform elastically to transform the support unit between HMD and HHD forms. This approach maintains structural simplicity while enabling form switching through material flexibility rather than mechanical complexity.
