Imaging Device Housing Bulging Sections for Load Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing imaging apparatus designs face issues with durability due to warping of the top cover and wiring board when a load is applied, potentially causing contact between the top cover and the lens module, which can lead to damage of components like the CPU and memory.
Innovation Solution
The design incorporates bulging sections in the housing that receive loads from the top cover via light guide and light blocking bodies, redirecting the force away from the wiring board, thereby preventing warping and enhancing durability without increasing the apparatus' thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the top cover is supported only at the outer edges by the housing, then the top cover can be simple in structure, but the wiring board warps when load is applied to the center, causing component damage
Solution Approach 1:
The housing is segmented into multiple functional sections: edge support portions for supporting the top cover outer edges, and bulging sections for receiving loads from the top cover center. This segmentation allows each section to perform its specific function, preventing load transfer to the wiring board while maintaining structural simplicity
Solution Approach 2:
The light guide body and light blocking body serve as intermediary structures between the top cover and the housing. They transmit loads from the top cover center to the housing bulging sections without allowing direct contact between the top cover and lens module, thereby protecting the wiring board from warping
2Reliability
If the space between the top cover and lens module is widened to prevent contact, then component damage is prevented, but the apparatus thickness increases
Solution Approach 1:
Instead of increasing the vertical space between the top cover and lens module, the solution redirects loads horizontally to the housing bulging sections. The light guide body and light blocking body transmit loads in a direction that utilizes the housing structure rather than requiring additional vertical clearance
Solution Approach 2:
The housing bulging sections are designed in advance to receive and absorb loads from the top cover center before these loads can transfer to the wiring board. This pre-positioned load reception structure prevents wiring board warping without requiring increased apparatus thickness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for a simple and durable imaging apparatus by ensuring that loads are absorbed by the bulging sections, reducing the risk of warping and component damage, while maintaining a compact size.
Implementation Method 1
a ring-shaped light guide body that diffuses light emitted from an illumination light emitting element toward a subject
Implementation Method 2
a ring-shaped light blocking body that blocks light rays such as that emitted from the illumination light emitting element and leaked from the spaces between components within the imaging apparatus
