Boss Fixing Member Design for Display Apparatus Size Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display apparatus configurations, particularly for large-sized electronic devices, are bulky due to the use of brackets and bosses made from different materials, leading to increased size and noise issues from thermal expansion differences.
Innovation Solution
A display apparatus design incorporating a boss fixing member with a combination hole and elastic material, allowing flexible insertion of bosses formed in the front and rear cases, eliminating the need for a conventional bracket and reducing overall size while mitigating noise from thermal expansion discrepancies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bracket is employed to combine front and rear cases together, then the structural integrity is improved, but the overall size of the display apparatus increases
Solution Approach 1:
The patent removes the separate bracket component from the assembly and integrates the combining function directly into the boss structures. The bosses are formed with combination holes that receive fastening elements, allowing the front and rear cases to be combined without requiring an additional bracket piece, thereby reducing overall size while maintaining structural integrity.
Solution Approach 2:
The patent merges the functions of the bracket and the bosses into a single integrated structure. The bosses are formed as integral parts of the front and rear cases with built-in combination holes, eliminating the need for a separate bracket component and reducing the number of parts while maintaining the case-combining function.
2Ease of manufacture
If bosses are formed from different materials than the bracket, then the manufacturing flexibility is improved, but thermal expansion differences cause contact noise
Solution Approach 1:
The patent forms the bosses and the bracket from the same metal material, ensuring they have identical thermal expansion coefficients. This homogeneous material selection prevents differential thermal expansion between the bosses and bracket, eliminating the contact noise problem while maintaining manufacturing flexibility through integral formation with the plastic cases.
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 solution effectively decreases the overall size of the display apparatus and prevents noise caused by thermal expansion differences, enhancing the structural integrity and reducing manufacturing costs by eliminating the need for a metal bracket.
Implementation Method 1
The boss insertion element includes an elastic material. For example, the boss insertion element includes rubber.

AI summary
A display apparatus includes a display module and a front case. The display module displays images. The display module includes a boss fixing member having a combination hole. The front case covers a first surface of the display module and has a first boss that is inserted into the combination hole to combine the front case to the display module. The first boss is formed at inside edges of the display module. The boss fixing member is positioned within the edges of the display module which define the outdimension of the display module.
