Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a structure is inserted into the gap between the electronic device and one side of the secondary battery to separate the secondary battery, then the secondary battery can be separated from the electronic device, but the force is concentrated on one side or the other side of the secondary battery, causing damage such as bending or warping
Solution Approach 1:
The insert unit is divided into a manipulation portion and a deformation portion, where the deformation portion is further divided into a bonded portion and a non-bonded portion. This segmentation allows the force application to be distributed across multiple regions of the secondary battery, preventing concentration of force on a single side that would cause bending or warping.
Solution Approach 2:
The insert unit has different properties in different regions: the manipulation portion has stronger rigidity for force application, while the deformation portion includes an elastically deformable material that can flex. The non-bonded portion is specifically designed to be deformable to push the battery out, while the bonded portion maintains attachment. This local differentiation of properties enables effective force distribution.
2Object-generated harmful factors
If the insert unit uses a rigid structure to apply separation force, then the separation can be achieved with less manipulation effort, but the rigid structure may cause bending or warping damage to the secondary battery
Solution Approach 1:
The insert unit utilizes changes in rigidity parameter along its structure. The manipulation portion maintains strong rigidity for effective force application, while the deformation portion transitions to an elastically deformable material that can flex and distribute forces. This gradient in rigidity parameter allows the system to apply sufficient separation force while avoiding damage through elastic deformation that absorbs and distributes mechanical stress.
3Reliability
If the deformation portion is made of elastically deformable material, then the force can be distributed to prevent bending or warping, but the manipulation portion needs stronger rigidity to apply effective separation force
Solution Approach 1:
The insert unit employs local quality by assigning different mechanical properties to different regions: the manipulation portion has stronger rigidity for force application, while the deformation portion includes an elastically deformable material. This localized differentiation of material properties allows each region to perform its specific function optimally without requiring the entire structure to be complex.
Solution Approach 2:
The insert unit is segmented into distinct functional regions: a manipulation portion for force application and a deformation portion with bonded and non-bonded sub-portions for flexible force distribution. This segmentation into functionally distinct segments allows the structure to achieve both rigidity where needed and flexibility where needed, reducing overall structural complexity while maintaining effectiveness.
