Elastic Bumper Frame for Tablet Drop Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tablet computers with fragile glass or plastic protection plates are prone to damage from accidental drops due to shock, as the protection plates are directly exposed and lack effective shock absorption.
Innovation Solution
Incorporating a strong metal or high-stiffness resin frame with a bumper portion that protrudes outside the housing, which absorbs shock upon impact by elastically supporting the display module and protection plate, preventing direct contact with the floor and distributing force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protection plate is entirely exposed at the surface for touch panel operation, then ease of operation is improved, but the protection plate becomes vulnerable to shock damage from drops
Solution Approach 1:
A bumper portion made of flexible or elastic material is introduced as an intermediary element between the external environment and the protection plate. This bumper protrudes from the housing to form a protective barrier that absorbs shock during drops, allowing the protection plate to remain exposed for touch operation while being protected from impact damage.
Solution Approach 2:
The bumper portion is pre-installed on the housing to provide cushioning protection before any drop occurs. This proactive protective measure ensures that when a drop happens, the shock is already absorbed by the bumper material, preventing direct impact on the fragile protection plate and display module.
2Measurement precision
If the protection plate is made of fragile glass or plastic for display quality, then display precision is improved, but shock resistance deteriorates
Solution Approach 1:
The bumper serves as a mediator that absorbs external shock forces before they reach the fragile protection plate. This allows the use of high-quality glass or plastic materials for optimal display clarity without compromising overall device durability, as the bumper intercepts impact forces.
Solution Approach 2:
The bumper converts harmful shock forces from drops into beneficial elastic deformation energy. By designing the bumper with energy-absorbing materials, the harmful impact is transformed into temporary elastic strain, protecting the fragile display components while maintaining their high-quality characteristics.
3Reliability
If a bumper portion is added to protect against shock, then reliability is improved, but device complexity increases
Solution Approach 1:
The bumper portion is merged with the housing structure, forming an integrated protective element. This combination approach adds protection functionality without requiring completely separate components, thereby limiting the increase in device complexity while still achieving improved shock resistance.
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 significantly reduces the likelihood of damage to the protection plate and display module by absorbing shock through the bumper portion, enhancing the tablet computer's shock resistance and protecting the internal components.
Implementation Method 1
the frame is provided with a bumper portion configured to protrude to the outside of the housing... which absorbs shock upon impact by elastically supporting the display module and protection plate
