Display Device Boss Insertion Element for Size Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration of liquid crystal display devices for large-sized electronic devices is bulky due to the use of a bracket and differences in thermal expansion between materials, leading to noise and increased size.
Innovation Solution
A display device design incorporating a boss fixing member with an elastic boss insertion element that allows flexible insertion of bosses into a combination hole, eliminating the need for a bracket and reducing overall size while accommodating thermal expansion differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bracket is used to combine front and rear cases, then the structural strength is improved, but the overall size of the display device increases
Solution Approach 1:
The patent merges the bracket function directly into the display module by forming a recess in the module housing that receives the boss. This integration eliminates the need for a separate bracket component, thereby maintaining structural strength while reducing the overall device volume.
Solution Approach 2:
The patent extracts the bracket function from a separate component and incorporates it directly into the display module structure. The recess formed in the module housing contains the boss, effectively removing the need for an external bracket and reducing overall device size.
2Ease of manufacture
If bosses are formed from different materials than the bracket, then the ease of manufacture is improved, but thermal expansion differences cause noise
Solution Approach 1:
The patent introduces a boss insertion element as an intermediary component between the boss and the recess. This insertion element acts as a buffer that accommodates thermal expansion differences between materials, preventing noise while allowing the use of different materials for ease of manufacture.
Solution Approach 2:
The patent changes the physical state or properties of the boss insertion element (using elastic material) to allow it to deform and accommodate thermal expansion differences. This parameter change enables the system to tolerate material differences without generating noise.
3Adaptability or versatility
If bosses are formed from different materials than the bracket, then the manufacturing flexibility is improved, but thermal expansion differences cause contact and noise
Solution Approach 1:
The boss insertion element serves as a mediator that allows different materials to be used for the boss and bracket while preventing thermal expansion issues. The elastic material of the insertion element absorbs the dimensional changes caused by differential thermal expansion.
Solution Approach 2:
The elastic properties of the boss insertion element allow it to dynamically adjust to thermal expansion differences. By changing its physical state (elastic deformation), it maintains contact pressure without generating noise from rigid thermal expansion conflicts.
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 reduces the overall size of the display device and prevents noise caused by thermal expansion differences, enhancing the device's compactness and reliability.
Implementation Method 1
The boss insertion element includes an elastic material. For example, the boss insertion element includes rubber.
Implementation Method 2
when the first and second bosses are formed from different materials than those of the bracket, thermal expansions of the bosses are different from a thermal expansion of the bracket

AI summary
A display device includes a display module, a first case and a boss insertion element having a combination hole. The first case covers a first surface of the display module and has a first boss which 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.
