Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If high temperature heating is used to dismantle the display module, then the adhesive's adhesiveness is reduced, but the display module is easily deformed or damaged
Solution Approach 1:
The patent changes the parameter used to control adhesive strength from temperature to voltage. By applying voltage to the electrically conductive adhesive, the adhesive strength can be precisely controlled without subjecting the display module to high temperatures that cause deformation or damage. This resolves the contradiction by finding an alternative parameter (voltage) that achieves the same goal (reducing adhesive strength for dismantling) without the harmful side effects (thermal damage).
Solution Approach 2:
The patent replaces the thermal mechanism (heating) with an electrical mechanism (voltage application) to control adhesive strength. Instead of using heat to weaken the adhesive bond, the system uses electrical voltage applied to the conductive adhesive, substituting a mechanical/thermal system with an electrical field-based system that provides more precise control and avoids thermal damage to the display module.
2Productivity
If forced dismantling is used to remove the display module, then the dismantling process is simplified, but the display module is easily deformed or damaged
Solution Approach 1:
The patent applies preliminary action by weakening the adhesive bond through voltage application before the actual dismantling process. By first reducing the adhesive strength electrically, the display module can then be removed easily and quickly without requiring forced dismantling that would cause deformation or damage. This preliminary weakening action enables both high productivity and maintained integrity.
Solution Approach 2:
The patent replaces forced mechanical dismantling with an electrical field-based approach. Instead of applying mechanical force that risks deformation, the system uses voltage applied to the conductive adhesive to weaken the bond, allowing the module to be removed gently and quickly. This substitution of mechanical force with electrical field control resolves the contradiction between dismantling speed and module integrity.
3Strength
If traditional adhesive is used to secure the display module, then the bonding strength is sufficient, but the dismantling process becomes difficult and complex
Solution Approach 1:
The patent changes the fundamental parameter of the adhesive material by making it electrically conductive. This allows the adhesive strength to be dynamically controlled through voltage application - maintaining strong bonding during normal operation (zero voltage) and enabling easy dismantling when voltage is applied. This parameter change resolves the contradiction by making the adhesive properties可调 (adjustable) rather than fixed.
Solution Approach 2:
The patent introduces dynamics to the adhesive system by enabling real-time control of adhesive strength through voltage application. The adhesive transitions from a static, permanently strong bond to a dynamic bond that can be weakened on demand. This dynamic control allows the system to maintain strong bonding during use while enabling easy dismantling for repairs, resolving the contradiction between bonding strength and dismantling ease.
4Reliability
If the display module is securely fastened with strong adhesive, then the reliability of the display assembly is improved, but the repair process becomes more difficult
Solution Approach 1:
The patent changes the adhesive material property by making it electrically conductive, enabling dynamic control of bond strength through voltage. During normal operation with zero voltage, the adhesive maintains strong bonding for reliability. During repair, applying voltage weakens the adhesive, enabling easy detachment. This parameter change resolves the contradiction by making the bond strength可调 (adjustable) based on operational state.
Solution Approach 2:
The patent gives the adhesive dual functionality: it serves as both a strong bonding agent during normal operation and as a controllable release mechanism during repair. The electrically conductive adhesive performs two opposite functions (bonding and releasing) based on voltage application, making the system universally applicable for both reliable assembly and easy repair without needing different adhesives for different purposes.
