Work Vehicle Headrest Cushion Structure With Hollow Bulge Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headrest configurations for work vehicles often require a large number of components, leading to increased manufacturing costs without optimal cushioning properties.
Innovation Solution
A headrest design featuring a cushion section with a bulging portion towards the user's head and recessed portions on the opposing surface, supported by a metal plate-like member, reduces component count and enhances cushioning efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional headrest configuration with multiple components (urethane foam wrapped in PVC film with board member support) is used, then head protection function is achieved, but manufacturing cost increases and component count increases
Solution Approach 1:
The invention merges the cushioning function and support function into a single integrated cushion section. The cushion section simultaneously provides impact absorption through its hollow portion and structural support through its bulging portion, eliminating the need for separate PVC wrapping and board member components while maintaining head protection reliability
Solution Approach 2:
The cushion section is designed as a multi-functional component that performs multiple roles: the hollow portion provides cushioning and shock absorption, while the bulging portion provides structural support and contact surface. This single component replaces what would traditionally require multiple separate parts, reducing device complexity without sacrificing protective function
2Reliability
If a traditional headrest configuration with multiple components is used, then head protection function is achieved, but manufacturing cost increases
Solution Approach 1:
By combining multiple functions into a single cushion section component, the invention reduces the total number of parts that need to be manufactured, assembled, and inventoried. This integration simplifies the manufacturing process and reduces costs associated with multiple component production while maintaining the required head protection reliability
Solution Approach 2:
The cushion section is designed to be self-sufficient, providing both cushioning and support functions without requiring additional components. The hollow portion and bulging portion work together within the single component to achieve protective function, eliminating the need for separate support structures and reducing manufacturing complexity
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
The design provides effective head protection while minimizing manufacturing costs by reducing component complexity and improving cushioning performance.
Implementation Method 1
the air in the hollow portion allows the cushion section to easily exhibit appropriate cushioning properties

AI summary
A headrest includes a cushion section configured to contact the back of a user's head, wherein the cushion section includes a hollow portion formed therein, and the cushion section includes a bulging portion bulging toward the back of the user's head at a central portion of an opposing surface of the cushion section, the opposing surface facing the back of the user's head.
